使用 Shiro 设计基于用户、角色、权限的通用权限管理系统

一、前言

在大型的信息管理系统中，经常涉及到权限管理系统
下面来个 demo，很多复杂的系统的设计都来自它
代码已经放到github上了，地址：https://github.com/larger5/shiro_urp.git

2018.4.3 版本0.5 在 SpringBoot 中使用 Shiro+MySQL 做登录拦截
2018.4.6 版本1.0 使用 Shiro 设计基于用户、角色、权限的通用权限管理系统
以后继续更新，如用户、角色、权限 CRUD 等，真正做到所谓的权限管理系统

二、数据库表的设计

下面使用 SpringBoot + JPA 的，自动生成如下的表
用户角色多对多、角色权限多对多，设计一个通用的权限系统（无论初衷是一个用户多个角色还是一个角色）

三、效果

说明：

①UI：

  使用了 LayUI 简单优化一下界面

②角色所含权限：

   p：select
   ip：select、insert
   vip：select、insert、update、delete

③权限：

   select
   insert
   update
   delete

以使用 itaem （VIP）为例

图解：
有：① select、insert、update、delete 权限 ② vip 角色
无：ip角色、p角色，点击后都是没有反应的

四、代码（github 平台上看）

① Controller（重点）

package com.cun.controller;

import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpSession;
import javax.validation.Valid;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authz.annotation.RequiresPermissions;
import org.apache.shiro.authz.annotation.RequiresRoles;
import org.apache.shiro.subject.Subject;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.cun.entity.User;

import springfox.documentation.swagger2.annotations.EnableSwagger2;

@EnableSwagger2
@RestController
@RequestMapping("/user")
public class UserController {

    @PostMapping("/login")
    public Map<String, Object> login(@Valid User user, BindingResult bindingResult, HttpSession session) {
        Map<String, Object> map = new HashMap<String, Object>();

        // 1、JSR303
        if (bindingResult.hasErrors()) {
            map.put("success", false);
            map.put("errorInfo", bindingResult.getFieldError().getDefaultMessage());
            return map;
        }

        // 2、Shiro
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(user.getUserName(), user.getPassword());
        try {
            subject.login(token);
            map.put("success", true);
            return map;
        } catch (Exception e) {
            e.printStackTrace();
            map.put("success", false);
            map.put("errorInfo", "用户名或者密码错误!");
            return map;
        }
    }

④ ShiroConfig（重点）

package com.cun.config;

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

import org.apache.shiro.spring.LifecycleBeanPostProcessor;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.DependsOn;
import org.apache.shiro.mgt.SecurityManager;
import com.cun.realm.MyRealm;

/**
 * Shiro配置类
 * @author linhongcun
 *
 */
@Configuration
public class ShiroConfig {
    /**
     * ShiroFilterFactoryBean 处理拦截资源文件问题。
     * 注意：单独一个ShiroFilterFactoryBean配置是或报错的，以为在
     * 初始化ShiroFilterFactoryBean的时候需要注入：SecurityManager
     *
     * Filter Chain定义说明 1、一个URL可以配置多个Filter，使用逗号分隔 2、当设置多个过滤器时，全部验证通过，才视为通过
     * 3、部分过滤器可指定参数，如perms，roles
     *
     */
    @Bean
    public ShiroFilterFactoryBean shirFilter(SecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();

        // 必须设置 SecurityManager
        shiroFilterFactoryBean.setSecurityManager(securityManager);

        // 如果不设置默认会自动寻找Web工程根目录下的"/login.jsp"页面
        shiroFilterFactoryBean.setLoginUrl("/login.html");

        // 拦截器.
        Map<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>();
        // 配置不会被拦截的链接 顺序判断
        filterChainDefinitionMap.put("/static/**", "anon");
        filterChainDefinitionMap.put("/user/login", "anon");
        //测试权限用
        filterChainDefinitionMap.put("/swagger-ui.html", "anon");

        // 配置退出过滤器,其中的具体的退出代码Shiro已经替我们实现了
        filterChainDefinitionMap.put("/logout", "logout");

        // 过滤链定义，从上向下顺序执行，一般将 /**放在最为下边 :这是一个坑呢，一不小心代码就不好使了;
        // ① authc:所有url都必须认证通过才可以访问; ② anon:所有url都都可以匿名访问
        filterChainDefinitionMap.put("/**", "authc");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        return shiroFilterFactoryBean;
    }

    @Bean
    public SecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        // 设置realm.
        securityManager.setRealm(myRealm());
        return securityManager;
    }

    /**
     * 身份认证realm; (这个需要自己写，账号密码校验；权限等)
     * 
     * @return
     */
    @Bean
    public MyRealm myRealm() {
        MyRealm myRealm = new MyRealm();
        return myRealm;
    }

    /**
     * Shiro生命周期处理器
     * @return
     */
    @Bean
    public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
        return new LifecycleBeanPostProcessor();
    }

    /**
     * 开启Shiro的注解(如@RequiresRoles,@RequiresPermissions),需借助SpringAOP扫描使用Shiro注解的类,并在必要时进行安全逻辑验证
     * 配置以下两个bean(DefaultAdvisorAutoProxyCreator(可选)和AuthorizationAttributeSourceAdvisor)即可实现此功能
     * @return
     */
    @Bean
    @DependsOn({ "lifecycleBeanPostProcessor" })
    public DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
        advisorAutoProxyCreator.setProxyTargetClass(true);
        return advisorAutoProxyCreator;
    }

    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor() {
        AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
        authorizationAttributeSourceAdvisor.setSecurityManager(securityManager());
        return authorizationAttributeSourceAdvisor;
    }
}

⑤ MyRealm（重点）

package com.cun.realm;

import java.util.HashSet;
import java.util.List;
import java.util.Set;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;

import com.cun.dao.PermissionDao;
import com.cun.dao.RoleDao;
import com.cun.dao.UserDao;
import com.cun.entity.Permission;
import com.cun.entity.Role;
import com.cun.entity.User;

public class MyRealm extends AuthorizingRealm {

    @Autowired
    private UserDao userDao;

    @Autowired
    private RoleDao roleDao;

    @Autowired
    private PermissionDao permissionDao;

    /**
     * 授权
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        String userName=(String) SecurityUtils.getSubject().getPrincipal();
        SimpleAuthorizationInfo info=new SimpleAuthorizationInfo();
        Set<String> roles=new HashSet<String>();
        List<Role> rolesByUserName = roleDao.getRolesByUserName(userName);
        for(Role role:rolesByUserName) {
            roles.add(role.getRoleName());
        }
        List<Permission> permissionsByUserName = permissionDao.getPermissionsByUserName(userName);
        for(Permission permission:permissionsByUserName) {
            info.addStringPermission(permission.getPermissionName());
        }
        info.setRoles(roles);
        return info;
    }

    /**
     * 认证
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("token.getPrincipal:" + token.getPrincipal());
        System.out.println("token.getCredentials:" + token.getCredentials());
        String userName = token.getPrincipal().toString();
        User user = userDao.getUserByUserName(userName);
        if (user != null) {
            // Object principal, Object credentials, String realmName
            AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(user.getUserName(), user.getPassword(), getName());
            return authcInfo;
        } else {
            return null;
        }
    }

}
