    }

    // 认证   springboot  2.1.x   可以直接使用
    // 密码编码:passwordEncoder
    // 在springsecurity5.0+  新增了很多加密的方法
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    
    

        // 这些数据正常应该从数据库读取

                .and()
                .withUser("root")

ShiroConfig类

  1. Shiro 需要两个配置文件类
package com.starcpdk.config;

import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.LinkedHashMap;
import java.util.Map;

@Configuration
public class ShiroConfig {
    
    
    // ShiroFiliterFactoryBean
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
    
    
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        // 设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);

        // 添加Shiro 的内置过滤器
        /*
            anno:无需认证 , 所有人都可以访问
            authc:必须认证了才能访问
            user:必须拥有记住我功能才能访问
            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能访问
            // filterMap.put("/user/add" , "authc");
        // filterMap.put("/user/update" , "authc");

         */

        Map<String, String> filterMap = new LinkedHashMap<>();

        // 授权 , 正常情况下 , 未授权应跳转到未授权的页面
        filterMap.put("/user/add" , "perms[user:add]");
        filterMap.put("/user/update" , "perms[user:update]");

        // 拦截
        filterMap.put("/user/*" , "authc");
        bean.setFilterChainDefinitionMap(filterMap);

        // 设置登录的请求
        bean.setLoginUrl("/toLogin");

        // 设置未授权页面
        bean.setUnauthorizedUrl("/noauth");
        return bean;
    }

    // DefaultWebSecurityManager
    @Bean(name = "securityManager")
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
    
    
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();

        // 关联UserRealm
        securityManager.setRealm(userRealm);
        return securityManager;
    }

    // 创建reaml对象 , remal对象需要自定义类
    @Bean(name = "userRealm")
    public UserRealm userRealm(){
    
    
        return new UserRealm();
    }

    // 整合ShiroDialect: 用来整合shiro thymeleaf
    @Bean
    public ShiroDialect getShiroDialect(){
    
    
        return new ShiroDialect();
    }
}

UserRealm类

// 自定义的realm
public class UserRealm extends AuthorizingRealm {
    
    

    @Autowired
    UserService userService;

    // 授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
    
    
        System.out.println("执行了授权");

        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();

        // 拿到当前登录的对象
        Subject subject = SecurityUtils.getSubject();
        User currentUser = (User) subject.getPrincipal(); // 拿到user对象

        // 添加了这个的授权user:add , 在ShiroConfig 类 中添加了perms[user:add]这个授权验证
        // 设置当前用户的权限
        info.addStringPermission(currentUser.getPerms());

        return info;
    }

    // 认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
    
    
        System.out.println("执行了认证");

        UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;

        // 用户名 , 密码 , 数据库取
        // 连接真实数据库
        User user = userService.queryUserByName(token.getUsername());

        if (user == null){
    
    
            return null; // 抛出异常  UnknownAccountException
        }

        // 登录成功创建session保存用户信息
        Subject currentSubject = SecurityUtils.getSubject();
        Session session = currentSubject.getSession();
        session.setAttribute("loginUser",user);

        // 可以加密 , MD5:   MD5盐值加密
        // 密码认证 : Shiro做
        return new SimpleAuthenticationInfo(user, user.getPwd(), "");
    }
}
