1 账户注销
1.1 在SecurityConfig中加入开启注销功能的代码
src/main/java/com/lv/config/SecurityConfig.java
package com.lv.config; import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder; //AOP : 拦截器! @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { //授权 @Override public void configure(HttpSecurity http) throws Exception { //首页所有人都可以访问,功能页只有对应的有权限的人才能访问 //请求授权的规则~(链式编程) http.authorizeRequests() .antMatchers("/").permitAll() .antMatchers("/level1/**").hasRole("vip1") .antMatchers("/level2/**").hasRole("vip2") .antMatchers("/level3/**").hasRole("vip3"); //没有权限默认会跳转到登录页,需要开启登录页面 http.formLogin(); //注销,开启了注销功能,跳到首页 http.logout().logoutSuccessUrl("/"); //防止跨站工具, get,post http.csrf().disable();//关闭csrf功能,注销失败可能的原因 } //认证,springboot 2.1.x 可以直接使用 //密码编码:PasswordEncoder //在Spring Security 5.0+ 新增了很多加密方法~ protected void configure(AuthenticationManagerBuilder auth) throws Exception { //这些数据正常应该从数据库中读 auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder()) .withUser("lv").password(new BCryptPasswordEncoder().encode("123456")).roles("vip2","vip3") .and() .withUser("root").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3") .withUser("guest").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1"); }
1.2 在index.html 添加注销的按钮
src/main/resources/templates/index.html
<!--登录注销--> <div class="right menu"> <div> <a class="item" th:href="@{/toLogin}"> <i class="address card icon"></i>登录 </a> </div> <div> <a class="item" th:href="@{/logout}"> <i class="sign-out icon"></i>注销 </a> </div> </div>
1.3 启动项目测试
访问登录页面,登录 guest 账户,该账户可以访问 level1的页面
登录成功后,点击 level1的链接,成功跳转到 level 页面,然后点击注销按钮
弹回到首页,再次点击点击 level1 页面
跳转到了登录页面
说明账户注销成功
2 权限控制
2.1 导入springsecurity和thymeleaf的整合依赖
pom.xml
<!-- springSecurity和thymeleaf整合包 --> <dependency> <groupId>org.thymeleaf.extras</groupId> <artifactId>thymeleaf-extras-springsecurity4</artifactId> <version>3.0.2.RELEASE</version> </dependency>
2.2 springboot版本降级
pom.xml
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.9.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent>
必须将springboot的版本降到2.0.9以下,否则 sec:authorize="isAuthenticated()" 不会生效.版本降低后,需要手动导入junit依赖,否则测试类会报错
<dependency> <groupId>org.junit.jupiter</groupId> <artifactId>junit-jupiter</artifactId> <version>RELEASE</version> <scope>test</scope> </dependency>
2.3 引入约束
在index.html的头文件中添加springsecurity和thymeleaf的整合约束
src/main/resources/templates/index.html
<html xmlns:th="http://www.thymeleaf.org" xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">
2.4 修改页面代码
主要修改两部分,一部分是登录状态下显示用户名,和注销按钮,未登录显示登录按钮 通过 sec:authorize="isAuthenticated()" 实现.另一部分是根据登录用户的权限显示不同的页面菜单,通过 sec:authorize="hasRole('vip1')" 实现.
src/main/resources/templates/index.html
<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org" xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"> <title>首页</title> <!--semantic-ui--> <link href="https://cdn.bootcss.com/semantic-ui/2.4.1/semantic.min.css" rel="stylesheet"> <link th:href="@{/qinjiang/css/qinstyle.css}" rel="stylesheet"> </head> <body> <!--主容器--> <div class="ui container"> <div class="ui segment" id="index-header-nav" th:fragment="nav-menu"> <div class="ui secondary menu"> <a class="item" th:href="@{/index}">首页</a> <!--登录注销--> <div class="right menu"> <!--如果未登录:显示登录按钮--> <div sec:authorize="!isAuthenticated()"> <a class="item" th:href="@{/toLogin}"> <i class="address card icon"></i>登录 </a> </div> <!--如果已登录:显示用户名和注销按钮--> <div sec:authorize="isAuthenticated()"> <a class="item"> 用户名:<span sec:authentication="name"></span> </a> </div> <div sec:authorize="isAuthenticated()"> <a class="item" th:href="@{/logout}"> <i class="sign-out icon"></i>注销 </a> </div> </div> </div> </div> <div class="ui segment" style="text-align: center"> <h3>Spring Security Study by 秦疆</h3> </div> <div> <br> <div class="ui three column stackable grid"> <!--菜单根据用户的角色动态实现--> <div class="column" sec:authorize="hasRole('vip1')"> <div class="ui raised segment"> <div class="ui"> <div class="content"> <h5 class="content">Level 1</h5> <hr> <div><a th:href="@{/level1/1}"><i class="bullhorn icon"></i> Level-1-1</a></div> <div><a th:href="@{/level1/2}"><i class="bullhorn icon"></i> Level-1-2</a></div> <div><a th:href="@{/level1/3}"><i class="bullhorn icon"></i> Level-1-3</a></div> </div> </div> </div> </div> <div class="column" sec:authorize="hasRole('vip2')"> <div class="ui raised segment"> <div class="ui"> <div class="content"> <h5 class="content">Level 2</h5> <hr> <div><a th:href="@{/level2/1}"><i class="bullhorn icon"></i> Level-2-1</a></div> <div><a th:href="@{/level2/2}"><i class="bullhorn icon"></i> Level-2-2</a></div> <div><a th:href="@{/level2/3}"><i class="bullhorn icon"></i> Level-2-3</a></div> </div> </div> </div> </div> <div class="column" sec:authorize="hasRole('vip3')"> <div class="ui raised segment"> <div class="ui"> <div class="content"> <h5 class="content">Level 3</h5> <hr> <div><a th:href="@{/level3/1}"><i class="bullhorn icon"></i> Level-3-1</a></div> <div><a th:href="@{/level3/2}"><i class="bullhorn icon"></i> Level-3-2</a></div> <div><a th:href="@{/level3/3}"><i class="bullhorn icon"></i> Level-3-3</a></div> </div> </div> </div> </div> </div> </div> </div> <script th:src="@{/qinjiang/js/jquery-3.1.1.min.js}"></script> <script th:src="@{/qinjiang/js/semantic.min.js}"></script> </body> </html>
2.5 重启程序测试
未登录页面
登录 lv 用户的页面
登录 geust 用户的页面
登录 root 用户的页面
页面显示都不同,权限控制成功实现
