基于springboot实现整合shiro实现登录认证以及授权过程解析

这篇文章主要介绍了基于springboot实现整合shiro实现登录认证以及授权过程解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

1.添加shiro的依赖

<dependency>
  <groupId>org.apache.shiro</groupId>
      <artifactId>shiro-spring-boot-web-
     starter</artifactId>
  <version>1.4.0</version>
</dependency>

2.先创建一个Realm

public class MyShiroRealm extends AuthorizingRealm {
  @Autowired
  private RoleService roleService;//角色模模块
  @Autowired
  private UserService userService;//用户模块
  @Autowired
  private PermissionService permissionService;//权限模块
  /**
   * 用户身份识别(登录")
   * @param authenticationToken
   * @return
   * @throws AuthenticationException
   */
  @Override
  protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
    UsernamePasswordToken authToken = (UsernamePasswordToken) authenticationToken;
    // 获取用户输入的账号
    String userName = authToken.getUsername();
　　　　　//通过账号查找用户信息
    User user= userService.selectUserOne(userName);// 将账户名,密码,盐值,getName()实例化到SimpleAuthenticationInfo中交给Shiro来管理
    SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
                              user,
                              user.getPassWord(),
　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　//这里是设置的密码盐
                              ByteSource.Util.bytes(user.getSalt()),
                              getName());
    return authenticationInfo;
  }

  /**
   * 访问控制。比如某个用户是否具有某个操作的使用权限
   * @param principalCollection
   * @return
   */
  @Override
  protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
    SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
    String userName = (String) principalCollection.getPrimaryPrincipal();
    if (userName == null) {
      log.error("授权失败，用户信息为空！！！");
      return null;
    }
    try {
      //获取用户角色集
      Set<String> listRole= roleService.findRoleByUsername(userName);
      simpleAuthorizationInfo.addRoles(listRole);
      //通过角色获取权限集
      for (String role : listRole) {
        Set<String> permission= permissionService.findPermissionByRole(role);
        simpleAuthorizationInfo.addStringPermissions(permission);
      }
      return simpleAuthorizationInfo;
    } catch (Exception e) {
      log.error("授权失败，请检查系统内部错误!!!", e);
    }
    return simpleAuthorizationInfo;
  }
}

3.创建shiro的配置类

@Configuration
public class ShiroConfiguration {
　　 //配置自定义的Realm
  @Bean
  public MyShiroRealm myShiroRealm(HashedCredentialsMatcher matcher){
    MyShiroRealm myShiroRealm= new MyShiroRealm();
　　　　　//在这里配置密码加密
    myShiroRealm.setCredentialsMatcher(matcher);
    return myShiroRealm;
  }

　　 //将Realm注册到securityManager中
  @Bean
  public DefaultWebSecurityManager securityManager(HashedCredentialsMatcher matcher){
    DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
    securityManager.setRealm(myShiroRealm(matcher));
    return securityManager;
  }

  //如果没有此name,将会找不到shiroFilter的Bean
  @Bean(name = "shiroFilter")
  public ShiroFilterFactoryBean shiroFilter(org.apache.shiro.mgt.SecurityManager securityManager){
    ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
    shiroFilterFactoryBean.setSecurityManager(securityManager);
    shiroFilterFactoryBean.setLoginUrl("/login");     //表示指定登录页面
    shiroFilterFactoryBean.setSuccessUrl("/user/list");  // 登录成功后要跳转的链接
    shiroFilterFactoryBean.setUnauthorizedUrl("/403");  //未授权页面

    Map<String,String> filterChainDefinitionMap = new LinkedHashMap<>();//拦截器, 配置不会被拦截的链接 顺序判断
    filterChainDefinitionMap.put("/login","anon");           //所有匿名用户均可访问到Controller层的该方法下
    filterChainDefinitionMap.put("/userLogin","anon");
    filterChainDefinitionMap.put("/image/**","anon");
    filterChainDefinitionMap.put("/css/**", "anon");
    filterChainDefinitionMap.put("/fonts/**","anon");
    filterChainDefinitionMap.put("/js/**","anon");
    filterChainDefinitionMap.put("/logout","logout");
    filterChainDefinitionMap.put("/**", "authc"); //authc:所有url都必须认证通过才可以访问; anon:所有url都都可以匿名访问
    //filterChainDefinitionMap.put("/**", "user");    //user表示配置记住我或认证通过可以访问的地址
    shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
    return shiroFilterFactoryBean;
  }

  /**
   * SpringShiroFilter首先注册到spring容器
   * 然后被包装成FilterRegistrationBean
   * 最后通过FilterRegistrationBean注册到servlet容器
   * @return
   */
  @Bean
  public FilterRegistrationBean delegatingFilterProxy(){
    FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
    DelegatingFilterProxy proxy = new DelegatingFilterProxy();
    proxy.setTargetFilterLifecycle(true);
    proxy.setTargetBeanName("shiroFilter");
    filterRegistrationBean.setFilter(proxy);
    return filterRegistrationBean;
  }
  //设置cookie
  @Bean
  public SimpleCookie rememberMeCookie(){
    //这个参数是cookie的名称,对应前端的checkbox的name=rememberMe
    SimpleCookie simpleCookie = new SimpleCookie("rememberMe");
    //记住我cookie生效时间3个小时(单位秒)
    simpleCookie.setMaxAge(10800);
    return simpleCookie;
  }
  //cookie管理对象,记住我功能
  @Bean
  public CookieRememberMeManager rememberMeManager(){
    CookieRememberMeManager cookieRememberMeManager = new CookieRememberMeManager();
    cookieRememberMeManager.setCookie(rememberMeCookie());
    return cookieRememberMeManager;
  }
  /**
   * 密码匹配凭证管理器（密码加密需要此配置）
   * @return
   */
  @Bean(name = "hashedCredentialsMatcher")
  public HashedCredentialsMatcher hashedCredentialsMatcher() {
    HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher();
    hashedCredentialsMatcher.setHashAlgorithmName("MD5");
    hashedCredentialsMatcher.setHashIterations(1024);// 设置加密次数
    return hashedCredentialsMatcher;
  }
  //如果没有这两个配置，可能会授权失败，所以依赖中还需要配置aop的依赖
  @Bean
  public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(HashedCredentialsMatcher matcher) {
    AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
    authorizationAttributeSourceAdvisor.setSecurityManager(securityManager(matcher));
    return authorizationAttributeSourceAdvisor;
  }
  @Bean
  @ConditionalOnMissingBean
  public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator(){
    DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator=new DefaultAdvisorAutoProxyCreator();
    defaultAdvisorAutoProxyCreator.setProxyTargetClass(true);
    return defaultAdvisorAutoProxyCreator;
  }
}

4.新建controller并写个登录的方法

/**
   * 登录页面 这里对应shiro中配置的shiroFilter的登录方法
   * @return
   */
  @GetMapping("/login")
  public String login() {
    return "user/login";
  }

//登录方法
  @PostMapping("/userLogin")
  public String toLogin( String userName,String passWord,Model model){
    UsernamePasswordToken token =new UsernamePasswordToken(userName,passWord);
    Subject subject = SecurityUtils.getSubject();
    try {
      //这里直接使用shiro的登录方法
      subject.login(token);
      return "redirect:user/list";
     //登录失败时，会catch到你的异常，异常通过全局处理
    } catch (UnknownAccountException e) {
      model.addAttribute("msg","该账号不存在");
    } catch (IncorrectCredentialsException e) {
      model.addAttribute("msg","密码错误，请重试");
    } catch (LockedAccountException e) {
      model.addAttribute("msg","该账户已被锁定,请联系管理员");
    } catch (Exception e) {
      model.addAttribute("msg","登录失败");
    }
    return "user/login";
  }
//添加
@RequestMapping("/insertUser")
@ResponseBody
public int insertUser(User user){
  //将uuid设置为密码盐值
  String salt = UUID.randomUUID().toString().replaceAll("-","");
  SimpleHash simpleHash = new SimpleHash("MD5", user.getPassWord(), salt, 1024);
　　 //添加用户信息
  user.setPassWord(simpleHash.toHex()).setValid(1).setSalt(salt).setCreateTime(new Date()).setDel(0);
  return userMapper.insertSelective(user);
}

5.创建全局异常处理类

@RestControllerAdvice
public class GlobalExceptionHandle {
  @ExceptionHandler(ShiroException.class)
  public String doHandleShiroException(ShiroException se,Model model) {
    se.printStackTrace();
  if(se instanceof UnknownAccountException) return "账户不存在！";
  else if(se instanceof LockedAccountException) return "账户已锁定，请联系管理员";
  else if(se instanceof IncorrectCredentialsException) return "密码错误，请重试";
  else if(se instanceof AuthorizationException) return "没有相应权限，请联系管理员";
  else return "登录失败";
　　}
}

权限需要开启权限注解才生效

@GetMapping("/userPageList")
  @ResponseBody
  @RequiresPermissions("user:view") //这里是用户对应的权限
  public PageList listPage(HttpServletRequest request){
    PageList pageList = new PageList();
    List<User> list= userService.findAllPage(request);//查询出的条数
    int totalCount = userService.countAll();//总记录数
    pageList.setRows(list);
    pageList.setTotal(totalCount);
    return pageList;
  }

shiro用户角色和权限表
