                </excludes>
            </configuration>
        </plugin>
    </plugins>
</build>

2.3 创建前端页面

在webapp文件夹中创建index.jsp和login.jsp
index.jsp

<%@page contentType="text/html;UTF-8" pageEncoding="UTF-8" isErrorPage="false" %>
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>
<body>
<%--受限资源--%>
<h1>系统主页</h1>
<ul>
    <li><a href="#" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >用户管理</a></li>
    <li><a href="#" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >商品管理</a></li>
    <li><a href="#" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >订单管理</a></li>
    <li><a href="#" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >物流管理</a></li>
</ul>
</body>
</html>

<%@page contentType="text/html;UTF-8" pageEncoding="UTF-8" isErrorPage="false" %>
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>
<body>
<h1>登录界面</h1>
<form action="${pageContext.request.contextPath}/user/login" method="post">
    用户名:<input type="text" name="username" > <br/>
    密码  : <input type="text" name="password"> <br>
    <input type="submit" value="登录">
</form>
</html>

2.4 配置视图信息

application.properties

server.port=8080
server.servlet.context-path=/shiro
spring.application.name=shiro

spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp

2.5 解决IDEA冲突问题

JSP 与IDEA 与SpringBoot存在一定的不兼容，修改此配置即可解决

2.6 测试搭建的环境

3. 整合Shiro

3.1 引入依赖

pom.xml

<!--引入shrio-->
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring-boot-starter</artifactId>
    <version>1.5.3</version>
</dependency>

3.2 自定义Realm

在shiro文件夹下创建realm文件夹

package com.test.shiro.realm;

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

/**
 * 自定义Realm
 */
public class CustomerRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        return null;
    }
}

3.3 Shiro配置

在config文件夹中创建ShiroConfig.java

@Configuration
public class ShiroConfig {
    //ShiroFilter过滤所有请求
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //给ShiroFilter配置安全管理器
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //配置系统受限资源
        //配置系统公共资源
        Map<String, String> map = new HashMap<String, String>();
        map.put("/index.jsp","authc");//表示这个资源需要认证和授权
        // 设置认证界面路径
        shiroFilterFactoryBean.setLoginUrl("/login.jsp");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);

        return shiroFilterFactoryBean;
    }
    //创建安全管理器
    @Bean
    public DefaultWebSecurityManager getDefaultWebSecurityManager(Realm realm) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(realm);
        return securityManager;
    }
    //创建自定义Realm
    @Bean
    public Realm getRealm() {
        CustomerRealm realm = new CustomerRealm();
        return realm;
    }
}

3.4 启动测试

输入http://localhost:8080/shiro/index.jsp，发现需要跳转到login.jsp

4. 常见过滤器

注意: shiro提供和多个默认的过滤器，我们可以用这些过滤器来配置控制指定url的权限：

5. 认证和退出

5.1 在index.jsp添加a标签

index.jsp

<a href="${pageContext.request.contextPath}/user/logout" rel="external nofollow"  rel="external nofollow" >退出登录</a>

5.2 编写controller

UserController.java

@Controller
@RequestMapping("/user")
public class UserController {
    @RequestMapping("logout")
    public String logout() {
        Subject subject = SecurityUtils.getSubject();
        subject.logout();
        return "redirect:/login.jsp";
    }
    @RequestMapping("/login")
    public String login(String username, String password) {
        //获取主题对象
        Subject subject = SecurityUtils.getSubject();
        try {
            subject.login(new UsernamePasswordToken(username,password));
            System.out.println("登录成功！！！");
            return "redirect:/index.jsp";
        } catch (UnknownAccountException e) {
            e.printStackTrace();
            System.out.println("用户错误！！！");
        } catch (IncorrectCredentialsException e) {
            System.out.println("密码错误！！！");
        }
        return "redirect:/login.jsp";
    }
}

5.3 修改自定义Realm

CustomerRealm.java

/**
 * 自定义Realm
 */
public class CustomerRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        String principal = (String) authenticationToken.getPrincipal();
        if ("zhangsan".equals(principal)) {
            return new SimpleAuthenticationInfo(principal,"123456",this.getName());
        }
        return null;
    }
}

5.4 修改ShiroConfig配置

ShiroConfig.java
公共资源一定是在受限资源上面，不然会造成死循环。

@Configuration
public class ShiroConfig {
    //ShiroFilter过滤所有请求
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //给ShiroFilter配置安全管理器
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //配置系统受限资源
        //配置系统公共资源
        Map<String, String> map = new HashMap<String, String>();
        map.put("/user/login","anon");//表示这个为公共资源 一定是在受限资源上面
        map.put("/**","authc");//表示这个受限资源需要认证和授权
        // 设置认证界面路径
        shiroFilterFactoryBean.setLoginUrl("/login.jsp");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);

        return shiroFilterFactoryBean;
    }
    //创建安全管理器
    @Bean
    public DefaultWebSecurityManager getDefaultWebSecurityManager(Realm realm) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(realm);
        return securityManager;
    }
    //创建自定义Realm
    @Bean
    public Realm getRealm() {
        CustomerRealm realm = new CustomerRealm();
        return realm;
    }
}

5.5 测试

登录正常，登出正常，未登录和登出后不能访问index.jsp

6. MDSalt的认证实现

6.1 创建数据库

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
-- ----------------------------
-- Table structure for t_user
-- ----------------------------
DROP TABLE IF EXISTS `t_user`;
CREATE TABLE `t_user` (
  `id` INT(6) NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(40) DEFAULT NULL,
  `password` VARCHAR(40) DEFAULT NULL,
  `salt` VARCHAR(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

SET FOREIGN_KEY_CHECKS = 1;

6.2 引入依赖

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/springboot_shrio?characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=123456

mybatis.type-aliases-package=com.test.entity
mybatis.mapper-locations=classpath:com/test/mapper/*.xml

6.4 创建实体类entity

User.java

@Data
@Accessors(chain = true)

    private String  id;
    private String username;
    private String password;
    private String salt;
}

6.5 创建DAO接口

    void save(User user);

    User findByUsername(String username);
}

6.6 编写Mapper配置文件

UserDao.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.test.dao.UserDao">

    <insert id="save" parameterType="User" useGeneratedKeys="true" keyProperty="id">
        insert into t_user values(#{id},#{username},#{password},#{salt})
    </insert>
    <select id="findByUsername" parameterType="String" resultType="User">
        select id,username,password,salt
        from t_user
        where username = #{username}
    </select>
</mapper>

6.7 创建Service接口

UserService.java

public interface UserService {
    //注册用户方法
    void register(User user);
    //根据用户名查找用户
    User findByUsername(String username);
}

6.8 编写生成随机盐工具类

SaltUtil.java

public class SaltUtil {
    public static String getSalt(int n) {
        char[] chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890!@#$%^&*()".toCharArray();
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < n; i++) {
            char c = chars[new Random().nextInt(chars.length)];
            sb.append(c);
        }
        return sb.toString();
    }

    public static void main(String[] args) {
        System.out.println(getSalt(4));
    }
}

6.9 编写Service实现类

UserServiceImpl.java

@Service("userService")
@Transactional
public class UserServiceImpl implements UserService {
    @Autowired
    private UserDao userDao;

    @Override
    public void register(User user) {
        //1.获取随机盐
        String salt = SaltUtil.getSalt(8);
        //2.将随机盐保存到数据
        user.setSalt(salt);
        //3.明文密码进行md5 + salt + hash散列
       Md5Hash MD5 = new Md5Hash(user.getPassword(),salt,1024);
       user.setPassword(MD5.toHex());
       userDao.save(user);
    }

    @Override
    public User findByUsername(String username) {
        return userDao.findByUsername(username);
    }
}

6.10 编写Controller

UserController.java

@Controller
@RequestMapping("/user")
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("/register")
    public String register(User user) {
        try {
            userService.register(user);
            return "redirect:/login.jsp";
        } catch (Exception e) {
            e.printStackTrace();
            return "redirect:/register.jsp";
        }
    }
    @RequestMapping("logout")
    public String logout() {
        Subject subject = SecurityUtils.getSubject();
        subject.logout();
        return "redirect:/login.jsp";
    }
    @RequestMapping("/login")
    public String login(String username, String password) {
        //获取主题对象
        Subject subject = SecurityUtils.getSubject();
        try {
            subject.login(new UsernamePasswordToken(username,password));
            System.out.println("登录成功！！！");
            return "redirect:/index.jsp";
        } catch (UnknownAccountException e) {
            e.printStackTrace();
            System.out.println("用户错误！！！");
        } catch (IncorrectCredentialsException e) {
            System.out.println("密码错误！！！");
        }
        return "redirect:/login.jsp";
    }

        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        String principal = (String) authenticationToken.getPrincipal();
        //获取UserService对象
        UserService userService = (UserService) ApplicationContextUtil.getBean("userService");
        //System.out.println(userService);
        User user = userService.findByUsername(principal);
        if (!ObjectUtils.isEmpty(user)) {
            return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), ByteSource.Util.bytes(user.getSalt()), this.getName());
        }
        return null;
    }
}

6.12 编写获取对象工具类

ApplicationContextUtil.java

@Component
public class ApplicationContextUtil implements ApplicationContextAware {

    private static ApplicationContext context;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.context = applicationContext;
    }
    //根据bean名字获取工厂中指定bean 对象

7. 授权实现

7.1 模拟数据实现授权

7.1.1 模拟数据

CustomerRealm.java

@Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        String principal = (String) principalCollection.getPrimaryPrincipal();
        if ("zhangsan".equals(principal)) {
            SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
            info.addRole("admin");
            info.addRole("user");
            info.addStringPermission("user:find:*");
            info.addStringPermission("admin:*");
            return info;

            return info;
        }
        return null;
    }
    ......
}

7.3 数据库实现权限授权

7.3.1 创建Dao接口

UserDao.java

	@Mapper
@Repository
public interface UserDao {
    //根据角色id查询权限集合
    Role findPermByRoleId(String id);
    //根据角色id查询权限集合

}

7.3.6 数据库表数据设置

7.3.7 测试

8. shiro使用缓存

8.1 Cache

8.1.1 Cache 作用

Cache 缓存: 计算机内存中一段数据

作用: 用来减轻DB的访问压力,从而提高系统的查询效率

流程:

8.1.2 使用shiro中默认EhCache实现缓存

1.引入依赖

<!--引入shiro和ehcache-->
<dependency>
  <groupId>org.apache.shiro</groupId>
  <artifactId>shiro-ehcache</artifactId>
  <version>1.5.3</version>
</dependency>

2.开启缓存

//3.创建自定义realm
@Bean
public Realm getRealm() {
    CustomerRealm realm = new CustomerRealm();
    HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();
    //设置使用MD5加密算法
    credentialsMatcher.setHashAlgorithmName("md5");
    //散列次数
    credentialsMatcher.setHashIterations(1024);
    realm.setCredentialsMatcher(credentialsMatcher);

    //开启缓存管理器
    realm.setCacheManager(new EhCacheManager());
    realm.setCachingEnabled(true);//开启缓存
    realm.setAuthenticationCachingEnabled(true);//开启认证缓存
    realm.setAuthenticationCacheName("authentication");
    realm.setAuthorizationCachingEnabled(true);//开启授权缓存
    realm.setAuthorizationCacheName("authorization");

    return realm;
}

8.1.3 测试

注意:如果控制台没有任何sql展示说明缓存已经开启

8.2 Redis

8.2.1 shiro中使用Redis作为缓存实现

1.引入redis依赖

<!--redis整合springboot-->
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

2.配置redis连接

spring.redis.port=6379
spring.redis.host=localhost
spring.redis.database=0

3.启动redis服务

4. 开发RedisCacheManager

自定义shiro缓存管理器
RedisCacheManager.java

import org.apache.shiro.cache.Cache;
import org.apache.shiro.cache.CacheException;
import org.apache.shiro.cache.CacheManager;

//自定义shiro缓存管理器
public class RedisCacheManager implements CacheManager {
    //参数1:认证或者是授权缓存的统一名称
    @Override
    public <K, V> Cache<K, V> getCache(String cacheName) throws CacheException {
        System.out.println(cacheName);
        return new RedisCache<K,V>(cacheName);
    }
}

5.开RedisCache实现

//自定义redis缓存的实现
public class RedisCache<k,v> implements Cache<k,v> {

    private String cacheName;

    public RedisCache() {
    }

    public RedisCache(String cacheName) {
        this.cacheName = cacheName;
    }

    @Override
    public v get(k k) throws CacheException {
        return (v) getRedisTemplate().opsForHash().get(this.cacheName, k.toString());
    }

    @Override
    public v put(k k, v v) throws CacheException {
        System.out.println("put key: "+k);
        System.out.println("put value:"+v);
        getRedisTemplate().opsForHash().put(this.cacheName,k.toString(), v);
        return null;
    }

    @Override
    public v remove(k k) throws CacheException {
        System.out.println("=============remove=============");
        return (v) getRedisTemplate().opsForHash().delete(this.cacheName,k.toString());
    }

    @Override
    public void clear() throws CacheException {
        System.out.println("=============clear==============");
        getRedisTemplate().delete(this.cacheName);
    }

    @Override
    public int size() {
        return getRedisTemplate().opsForHash().size(this.cacheName).intValue();
    }

    @Override
    public Set<k> keys() {
        return getRedisTemplate().opsForHash().keys(this.cacheName);
    }

    @Override
    public Collection<v> values() {
        return getRedisTemplate().opsForHash().values(this.cacheName);
    }

    private RedisTemplate getRedisTemplate(){
        RedisTemplate redisTemplate = (RedisTemplate) ApplicationContextUtil.getBean("redisTemplate");
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        return redisTemplate;
    }
}

6. 启动项目测试发现报错错误解释: 由于shiro中提供的simpleByteSource实现没有实现序列化,所有在认证时出现错误信息

解决方案如下：
实现实体类序列化
自定义salt实现实现序列化接口

import org.apache.shiro.codec.Base64;
import org.apache.shiro.codec.CodecSupport;
import org.apache.shiro.codec.Hex;
import org.apache.shiro.util.ByteSource;

import java.io.File;
import java.io.InputStream;
import java.io.Serializable;
import java.util.Arrays;
//自定义salt实现 实现序列化接口
public class MyByteSource implements ByteSource, Serializable {
    private  byte[] bytes;
    private String cachedHex;
    private String cachedBase64;
    public MyByteSource(byte[] bytes) {
        this.bytes = bytes;
    }
    public MyByteSource(char[] chars) {
        this.bytes = CodecSupport.toBytes(chars);
    public MyByteSource(String string) {
        this.bytes = CodecSupport.toBytes(string);
    public MyByteSource(ByteSource source) {
        this.bytes = source.getBytes();
    public MyByteSource(File file) {
        this.bytes = (new MyByteSource.BytesHelper()).getBytes(file);
    public MyByteSource(InputStream stream) {
        this.bytes = (new MyByteSource.BytesHelper()).getBytes(stream);
    public static boolean isCompatible(Object o) {
        return o instanceof byte[] || o instanceof char[] || o instanceof String || o instanceof ByteSource || o instanceof File || o instanceof InputStream;
    public byte[] getBytes() {
        return this.bytes;
    public boolean isEmpty() {
        return this.bytes == null || this.bytes.length == 0;
    public String toHex() {
        if (this.cachedHex == null) {
            this.cachedHex = Hex.encodeToString(this.getBytes());
        }
        return this.cachedHex;
    public String toBase64() {
        if (this.cachedBase64 == null) {
            this.cachedBase64 = Base64.encodeToString(this.getBytes());
        return this.cachedBase64;
    public String toString() {
        return this.toBase64();
    public int hashCode() {
        return this.bytes != null && this.bytes.length != 0 ? Arrays.hashCode(this.bytes) : 0;
    public boolean equals(Object o) {
        if (o == this) {
            return true;
        } else if (o instanceof ByteSource) {
            ByteSource bs = (ByteSource)o;
            return Arrays.equals(this.getBytes(), bs.getBytes());
        } else {
            return false;
    private static final class BytesHelper extends CodecSupport {
        private BytesHelper() {
        public byte[] getBytes(File file) {
            return this.toBytes(file);
        public byte[] getBytes(InputStream stream) {
            return this.toBytes(stream);
}

修改自定义realm中使用的salt

@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
    String principal = (String) authenticationToken.getPrincipal();
    //获取UserService对象
    UserService userService = (UserService) ApplicationContextUtil.getBean("userService");
    //System.out.println(userService);
    User user = userService.findByUsername(principal);
    if (!ObjectUtils.isEmpty(user)) {
        return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), new MyByteSource(user.getSalt()), this.getName());
    }
    return null;
}

}

9.2 开发页面加入验证码

<form action="${pageContext.request.contextPath}/user/login" method="post">
    用户名:<input type="text" name="username"> 

    密码 : <input type="text" name="password"> 

    请输入验证码: <input type="text" name="code"><img src="${pageContext.request.contextPath}/user/getImage" alt="">

    <input type="submit" value="登录">
</form>

9.3 开发控制器

@RequestMapping("getImage")
public void getImage(HttpSession session, HttpServletResponse response) throws IOException {
  //生成验证码
  String code = VerifyCodeUtils.generateVerifyCode(4);
  //验证码放入session
  session.setAttribute("code",code);
  //验证码存入图片
  ServletOutputStream os = response.getOutputStream();
  response.setContentType("image/png");
  VerifyCodeUtils.outputImage(220,60,os,code);
}

9.4 放行验证码

ShiroConfig.java

map.put("/user/getImage","anon");//验证码

9.5 修改认证流程

@RequestMapping("login")
public String login(String username, String password,String code,HttpSession session) {
    //比较验证码
    String codes = (String) session.getAttribute("code");
    try {
        if (codes.equalsIgnoreCase(code)){
            //获取主体对象
            Subject subject = SecurityUtils.getSubject();
                subject.login(new UsernamePasswordToken(username, password));
                return "redirect:/index.jsp";
        }else{
            throw new RuntimeException("验证码错误!");
        }
    } catch (UnknownAccountException e) {
        e.printStackTrace();
        System.out.println("用户名错误!");
    } catch (IncorrectCredentialsException e) {
        e.printStackTrace();
        System.out.println("密码错误!");
    }catch (Exception e){
        e.printStackTrace();
        System.out.println(e.getMessage());
    }
    return "redirect:/login.jsp";
}

9.6 启动测试

10. shiro标签在jsp使用

需要在jsp页面中引入标签
<%@ taglib uri="http://shiro.apache.org/tags" prefix="shiro" %>
标签：
<shiro:authenticated> 登录之后
<shiro:notAuthenticated> 不在登录状态时
<shiro:guest> 用户在没有RememberMe时
<shiro:user> 用户在RememberMe时
<shiro:hasAnyRoles name="abc,123" > 在有abc或者123角色时
<shiro:hasRole name="abc"> 拥有角色abc
<shiro:lacksRole name="abc"> 没有角色abc
<shiro:hasPermission name="abc"> 拥有权限资源abc <shiro:lacksPermission name="abc"> 没有abc权限资源
<shiro:principal> 显示用户身份名称
<shiro:principal property="username"/> 显示用户身份中的属性值

11. Shiro整合springboot之thymeleaf权限控制

11.1 引入依赖

<dependency>
    <groupId>com.github.theborakompanioni</groupId>
    <artifactId>thymeleaf-extras-shiro</artifactId>
    <version>2.0.0</version>
</dependency>

11.2 页面中引入命名空间

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"
      xmlns:shiro="http://www.pollix.at/thymeleaf/shiro">

11.3 常见权限控制标签使用

<!-- 验证当前用户是否为“访客”，即未认证（包含未记住）的用户。 -->
<p shiro:guest="">Please <a href="login.html" rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >login</a></p>

<!-- 认证通过或已记住的用户。 -->
<p shiro:user="">
    Welcome back John! Not John? Click <a href="login.html" rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >here</a> to login.
</p>
<!-- 已认证通过的用户。不包含已记住的用户，这是与user标签的区别所在。 -->
<p shiro:authenticated="">
    Hello, <span shiro:principal=""></span>, how are you today?
<a shiro:authenticated="" href="updateAccount.html" rel="external nofollow" >Update your contact information</a>
<!-- 输出当前用户信息，通常为登录帐号信息。 -->
<p>Hello, <shiro:principal/>, how are you today?</p>
<!-- 未认证通过用户，与authenticated标签相对应。与guest标签的区别是，该标签包含已记住用户。 -->
<p shiro:notAuthenticated="">
    Please <a href="login.html" rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >login</a> in order to update your credit card information.
<!-- 验证当前用户是否属于该角色。 -->
<a shiro:hasRole="admin" href="admin.html" rel="external nofollow" >Administer the system</a><!-- 拥有该角色 -->
<!-- 与hasRole标签逻辑相反，当用户不属于该角色时验证通过。 -->
<p shiro:lacksRole="developer"><!-- 没有该角色 -->
    Sorry, you are not allowed to developer the system.
<!-- 验证当前用户是否属于以下所有角色。 -->
<p shiro:hasAllRoles="developer, 2"><!-- 角色与判断 -->
    You are a developer and a admin.
<!-- 验证当前用户是否属于以下任意一个角色。  -->
<p shiro:hasAnyRoles="admin, vip, developer,1"><!-- 角色或判断 -->
    You are a admin, vip, or developer.
<!--验证当前用户是否拥有指定权限。  -->
<a shiro:hasPermission="userInfo:add" href="createUser.html" rel="external nofollow"  rel="external nofollow" >添加用户</a><!-- 拥有权限 -->
<!-- 与hasPermission标签逻辑相反，当前用户没有制定权限时，验证通过。 -->
<p shiro:lacksPermission="userInfo:del"><!-- 没有权限 -->
    Sorry, you are not allowed to delete user accounts.
<!-- 验证当前用户是否拥有以下所有角色。 -->
<p shiro:hasAllPermissions="userInfo:view, userInfo:add"><!-- 权限与判断 -->
    You can see or add users.
<!-- 验证当前用户是否拥有以下任意一个权限。  -->
<p shiro:hasAnyPermissions="userInfo:view, userInfo:del"><!-- 权限或判断 -->
    You can see or delete users.
<a shiro:hasPermission="pp" href="createUser.html" rel="external nofollow"  rel="external nofollow" >Create a new User</a>

11.4 加入shiro的方言配置

页面标签不起作用一定要记住加入方言处理

@Bean(name = "shiroDialect")
public ShiroDialect shiroDialect(){
  return new ShiroDialect();
}
