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;
}
}
}
