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：selectip：select、insertvip：select、insert、update、delete

③权限：

   selectinsertupdatedelete

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、JSR303if (bindingResult.hasErrors()) {map.put("success", false);map.put("errorInfo", bindingResult.getFieldError().getDefaultMessage());return map;}// 2、ShiroSubject 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**/@Beanpublic ShiroFilterFactoryBean shirFilter(SecurityManager securityManager) {ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();// 必须设置 SecurityManagershiroFilterFactoryBean.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;}@Beanpublic 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*/@Beanpublic MyRealm myRealm() {MyRealm myRealm = new MyRealm();return myRealm;}/*** Shiro生命周期处理器* @return*/@Beanpublic 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;}@Beanpublic 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 {@Autowiredprivate UserDao userDao;@Autowiredprivate RoleDao roleDao;@Autowiredprivate PermissionDao permissionDao;/*** 授权*/@Overrideprotected 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*/@Overrideprotected 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 realmNameAuthenticationInfo authcInfo = new SimpleAuthenticationInfo(user.getUserName(), user.getPassword(), getName());return authcInfo;} else {return null;}}}
