Shiro+SpringBoot认证

该博客以Web为基础

一、引入依赖

　　　　shiro-all包含shiro所有的包、shiro-core是核心包、shiro-web是与web整合、shiro-spring是与spring整合、shiro-ehcache是与EHCache整合、shiro-quartz是与任务调度quartz整合等等。这里我们只需要引入shiro-spring即可。

2 <dependency> 3 <groupId>org.apache.shirogroupId> 4 <artifactId>shiro-springartifactId> 5 <version>1.5.3version> 6 dependency>

 二、Controller层

@RestController
@RequestMapping("/account")
public class AccountController {

/**
 * 登录
 * @param username
　* @param password
 * @return
 */
　　@PostMapping(path = "/login")
    public ResultMsg login(
            @RequestParam(value = "aaccount")String username,
 @RequestParam(value = "apassword")String pwd,
 @RequestParam("check") Integer check ) {
 ResultMsg resultMsg = new ResultMsg();
 // 获取当前用户
 Subject subject = SecurityUtils.getSubject();
 /**
 * 判断当前用户是否已经认证过
 */
// System.out.println("是否记住我==="+subject.isRemembered());
 if (!subject.isAuthenticated()) {
 // 封装用户的登录数据
 UsernamePasswordToken token = new UsernamePasswordToken(username,pwd);
 Boolean rememberMe = check == 1 ? true:false;
 System.out.println(rememberMe);
 token.setRememberMe(rememberMe); //记住我
 try {
 subject.login(token); //登录认证
 resultMsg.setState(200);
 resultMsg.setMsg("登录成功");
 return resultMsg;
 } catch (UnknownAccountException u) {
 System.err.println("用户不存在");
 resultMsg.setState(412);
 resultMsg.setMsg("用户不存在");
 return resultMsg;
 } catch (IncorrectCredentialsException i) {
 System.err.println("密码错误");
 resultMsg.setState(412);
 resultMsg.setMsg("密码错误");
 return resultMsg;
 } catch (LockedAccountException l) {
 System.err.println("账户锁定");
 resultMsg.setState(412);
 resultMsg.setMsg("账户锁定");
 return resultMsg;
 }
 } else {
 resultMsg.setState(403);
 resultMsg.setMsg("此账户已在其他地方登录,是否强制下线?");
 return resultMsg;
 }
 }
　　
　　/**
 * 退出登录
 * @param num
 * @return
 */
 @GetMapping(path = "/loginout")
 public ResultMsg loginOut(Integer num) {
 ResultMsg resultMsg = new ResultMsg();
// 获取当前用户
 Subject subject = SecurityUtils.getSubject();
 subject.logout();//退出当前登录
 resultMsg.setState(200);
 if (num == 1) {
 resultMsg.setMsg("已下线!");
 } else {
 resultMsg.setMsg("当前用户已退出!");
 }
 return resultMsg;

 }
　　
　　/**
 　　* 未认证返回登录页面
 　　* @return
 　　*/
　　@GetMapping(path = "/login")
　　public ModelAndView login() {
 　　ModelAndView mv = new ModelAndView("/user/login");
 　　return mv;
　　}


}

Shiro核心配置

Shiro配置类

ShiroConfig.java

主要创建三大Bean对象

• ShiroFilterFactoryBean（拦截一切请求）3
• DefaultSecurityManager（安全管理器）2
• 自定义Realm 继承 AuthorizingRealm（主要用于认证和授权）1

建议创建顺序逆行

package com.hk.aefz.shiro.config;

@Configuration
public class ShiroConfig {

    //    ShiroFliterFactoryBean 3
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(
            @Qualifier("securityManager") DefaultWebSecurityManager securityManager
    ) {
        ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();
//        设置安全管理器
        factoryBean.setSecurityManager(securityManager);
//        添加Shiro内置过滤器
　　　　/*
            anon：无需认证就可以访问
            authc：必须认证才可以访问
            user：必须拥有记住我功能才可以访问
            perms：拥有对某个资源的权限才能访问
            role：拥有某个角色权限才可以访问
         */

        Map filterMap = new LinkedHashMap<>();
//        匿名访问
        filterMap.put("/navigation/index","anon");
        filterMap.put("/navigation/blogdetails","anon");
        filterMap.put("/navigation/login","anon");
        filterMap.put("/navigation/register","anon");
//        需要角色
        filterMap.put("/navigation/personblog","authc,roles[blogger]");
        filterMap.put("/navigation/admin-blog","authc,roles[blogger]");
        filterMap.put("/navigation/**","user");
        factoryBean.setFilterChainDefinitionMap(filterMap);
//        拦截后返回登录页面
        factoryBean.setLoginUrl("/navigation/login");return factoryBean;
    }

    //  DefaultWebSecurityManager 2 安全管理器
    @Bean(name = "securityManager")
    public DefaultWebSecurityManager getDefaultWebSecurityManager(
            @Qualifier("userRealm") UserRealm userRealm,
    ) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
//        关联UserRealm
        securityManager.setRealm(userRealm);
        return securityManager;
    }
    //    创建UserRealm类 需要自定义 1
    @Bean
    public UserRealm  userRealm() {
        UserRealm userRealm = new UserRealm();
   
        return userRealm;
    }
    }
}

自定义Relam类

继承AuthorizingRealm类

/**
 * 自定义UserRealm
 */
public class UserRealm extends AuthorizingRealm {

//    注入AccountController
    @Autowired
    private AccountController accountController;

    @Autowired
    private UserInfoService userInfoService;

    @Autowired
    private AccountService accountService;

//    授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        System.err.println("执行了授权.........");return null;
    }

//    认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.err.println("执行了认证...........");
//        获取当前登录账户
        UsernamePasswordToken accountToken = (UsernamePasswordToken) token;
        String username = accountToken.getUsername(); // 获取当前账号
//        连接数据库进行登录验证
        Account account = accountController.selectByName(username);
        System.out.println(account);
        if (account == null) {
            return null; //抛出 UnknownAccountException 异常
        }
//         密码认证 shiro做 存在泄密
        SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(account, account.getApassword(), account.getAaccount());return info;
    }

}

测试

使用PostMan进行登录测试
