包含前后端技术栈、功能介绍、角色权限设置及数据库设计等内容，附源码下载链接，是学习权限管理系统的优质资源。
前言
最近一直在学习权限框架，光学不敲，那肯定不行，所以有了这个项目。项目实现了jwt无状态登录、redis缓存、token续期和可控。算是个比较通用且有亮点的权限管理项目吧。🤭
一、项目介绍
1.运行
项目下载
gitee：https://gitee.com/wusupweilgy/springboot-vue.git
蓝奏云：https://wwp.lanzoup.com/iR1AY0ttqcob
2.技术栈
前端：vue2，element-ui、axios、echars组件
后端：springboot、mybatis-plus、shiro、jwt、redis
3.功能
用户、角色和菜单的权限管理
统计在线人数、注册人数等
个人密码、用户信息的修改
根据角色不同，前端动态渲染菜单导航
4.角色权限介绍
admin角色拥有删除功能，其他角色没有
admin和vip角色能查看用户信息，普通用户不行
admin和vip能进行添加操作，普通用户不行
个人信息和修改密码，登录过就可以访问
二、流程讲解
1.用户点击注册，系统将密码加密后存入数据库中。
2.用户登录，主要是校验账号密码并生成 token(jwt)，然后存储到Redis，这里存的是签发时间，比token(jwt)中设置的过期时间长，为了实现token的自动续期。文章末尾我有细说。
3.用户访问需要认证的资源时，需要进行token校验和续期判断
三、数据库
E-R图设计
没有加外键，因为增加会造成数据库压力。实体表都加入了逻辑删除字段。

}2.JWTFilter
主要作用就是拦截请求，判断请求头中书否携带 token。如果携带，就交给 Realm 处理。

}3.JwtToken
shiro 在没有和 jwt 整合之前，用户的账号密码被封装成了 UsernamePasswordToken 对象，UsernamePasswordToken 其实是 AuthenticationToken 的实现类。这里既然要和 jwt 整合，JWTFilter 传递给 Realm 的 token 必须是 AuthenticationToken 的实现类。
import org.apache.shiro.authc.AuthenticationToken;
public class JWTToken implements AuthenticationToken {
private String token;
public JWTToken(String token){
this.token=token;
}
@Override
public Object getPrincipal() {
return token;
}
@Override
public Object getCredentials() {
return token;
}
}4.自定义 Realm
继承 AuthorizingRealm从数据库中读取用户数据，实现认证和授权两个方法
import com.wusuowei.shiro_jwt.model.po.Menu;
import com.wusuowei.shiro_jwt.model.po.Role;
import com.wusuowei.shiro_jwt.model.po.User;

import com.wusuowei.shiro_jwt.service.UserService;
import com.wusuowei.shiro_jwt.utils.JWTUtil;
import com.wusuowei.shiro_jwt.utils.RedisUtil;
import org.apache.commons.lang3.StringUtils;
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;

@Component

private Long REFRESHEXPIRE;
@Autowired
private UserService userService;
@Autowired
private RoleService roleService;
@Autowired
private MenuService menuService;
@Autowired
private RedisUtil redisUtil;
//根据token判断此Authenticator是否使用该realm
//必须重写不然shiro会报错
@Override
public boolean supports(AuthenticationToken token) {
return token instanceof JWTToken;
}
/**
* 只有当需要检测用户权限的时候才会调用此方法，例如@RequiresRoles,@RequiresPermissions之类的
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
System.out.println("授权~~~~~");
User user = (User) principals.getPrimaryPrincipal();
String uid = String.valueOf(user.getId());
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
List<Role> redisRoles = (List<Role>) redisUtil.hget("userPower", "roles:"+uid);
List<Menu> redisPermissions = (List<Menu>) redisUtil.hget("userPower", "permission:"+uid);
if (redisRoles != null && redisPermissions != null) {
info.addRoles(redisRoles.stream().map(Role::getRoleKey).collect(Collectors.toSet()));
info.addStringPermissions(redisPermissions.stream().filter(item -> StringUtils.isNotBlank(item.getPermission())).map(Menu::getPermission).collect(Collectors.toSet()));
return info;
}
//查询数据库来获取用户的角色
List<Role> roles = roleService.getRoles(uid);
info.addRoles(roles.stream().map(Role::getRoleKey).collect(Collectors.toSet()));
//查询数据库来获取用户的权限

Set<String> collect = permissions.stream().filter(item -> StringUtils.isNotBlank(item.getPermission())).map(Menu::getPermission).collect(Collectors.toSet());
info.addStringPermissions(collect);
redisUtil.hset("userPower", "roles:" + uid, roles, REFRESHEXPIRE);
redisUtil.hset("userPower", "permissions:" + uid, collect, REFRESHEXPIRE);
return info;
}
/**
* 默认使用此方法进行用户名正确与否验证，错误抛出异常即可，在需要用户认证和鉴权的时候才会调用
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("认证~~~~~~~");
String jwt = (String) token.getCredentials();
String uid = JWTUtil.getUserId(jwt);
User redisUser = (User) redisUtil.get("userInfo:" + uid);
if (redisUser != null) {
return new SimpleAuthenticationInfo(redisUser, jwt, "MyRealm");
}
User user = userService.getById(uid);
if (user == null) {
throw new AuthenticationException("该用户不存在");
}
redisUtil.hset("userInfo",uid, user, REFRESHEXPIRE);
return new SimpleAuthenticationInfo(user, jwt, "MyRealm");
}
}5.配置Shiro
ShiroConfig主要配置了：过滤器、安全管理器和不进行拦截的路径，比如登录
import com.wusuowei.shiro_jwt.filter.JWTFilter;
import com.wusuowei.shiro_jwt.shiro.MyRealm;
import org.apache.shiro.mgt.DefaultSessionStorageEvaluator;
import org.apache.shiro.mgt.DefaultSubjectDAO;
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.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.servlet.Filter;
import java.util.LinkedHashMap;
@Configuration
public class ShiroConfig {
@Bean(name = "securityManager")
public DefaultWebSecurityManager securityManager(MyRealm myRealm) {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
// 设置自定义 realm.
securityManager.setRealm(myRealm);
//关闭session
DefaultSubjectDAO subjectDAO = new DefaultSubjectDAO();
DefaultSessionStorageEvaluator sessionStorageEvaluator = new DefaultSessionStorageEvaluator();
sessionStorageEvaluator.setSessionStorageEnabled(false);
subjectDAO.setSessionStorageEvaluator(sessionStorageEvaluator);
securityManager.setSubjectDAO(subjectDAO);
return securityManager;
}
/**
* 先走 filter ，然后 filter 如果检测到请求头存在 token，则用 token 去 login，走 Realm 去验证
*/
@Bean
public ShiroFilterFactoryBean factory(@Qualifier("securityManager") DefaultWebSecurityManager securityManager) {
ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();
factoryBean.setSecurityManager(securityManager);
// 添加自己的过滤器并且取名为jwt
LinkedHashMap<String, Filter> filterMap = new LinkedHashMap<>();
//设置我们自定义的JWT过滤器
filterMap.put("jwt", new JWTFilter());
factoryBean.setFilters(filterMap);
// 设置无权限时跳转的 url;
factoryBean.setUnauthorizedUrl("/unauthorized/无权限");
LinkedHashMap<String, String> filterRuleMap = new LinkedHashMap<>();
// 访问 /unauthorized/** 不通过JWTFilter
filterRuleMap.put("/unauthorized/**", "anon");
filterRuleMap.put("/login", "anon");
filterRuleMap.put("/register", "anon");
filterRuleMap.put("/check", "anon");
filterRuleMap.put("/files/**", "anon");
filterRuleMap.put("/test2", "anon");
// filterRuleMap.put("/logout", "anon");
// 所有请求通过我们自己的JWT Filter
filterRuleMap.put("/**", "jwt");
factoryBean.setFilterChainDefinitionMap(filterRuleMap);
return factoryBean;
}
/**
* 添加注解支持，如果不加的话很有可能注解失效
*/
@Bean
public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
defaultAdvisorAutoProxyCreator.setProxyTargetClass(true);
return defaultAdvisorAutoProxyCreator;
}
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(@Qualifier("securityManager") DefaultWebSecurityManager securityManager) {
AuthorizationAttributeSourceAdvisor advisor = new AuthorizationAttributeSourceAdvisor();
advisor.setSecurityManager(securityManager);
return advisor;
}
@Bean
public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
return new LifecycleBeanPostProcessor();
}
}五、项目核心逻辑介绍
1.jwt无状态登录
在微服务中我们一般采用的是无状态登录，而传统的session方式，在前后端分离的微服务架构下，如继续使用则必须要解决跨域sessionId问题、集群session共享问题等等。这显然是费力不讨好的事，而整合shiro，它的默认实现就是通过session的方式。
原因：
（1）shiro默认的拦截跳转都是跳转url页面，而前后端分离后，后端并无权干涉页面跳转。
（2）shiro默认使用的登录拦截校验机制恰恰就是使用的session。
解决：在这个系统中，我通过在ShiroConfig中配置filterRuleMap.put("/login", "anon");放行登录请求，然后登录成功后生成token并返回给前端，之后前端的每次请求都携带这个token，后端的JWTFilter进行过滤判断，然后通过调用getSubject(request, response).login(jwt);交给MyRealm进行认证、授权。
2.token可控
为什么要token可控。因为如果用户登录好几次，拿到很多token，用户就可以通过这些token（没有过期且正确）中的任意一个进行访问。但是如果我们想控制用户的登录，实现一些功能，比如让能统计在线人数，就需要实现token的可控。
解决：登录认证通过后返回AccessToken信息(在AccessToken中保存当前的时间和用户id)，同时在Redis中设置一条Key为用户id，Value为当前时间戳(登录时间和token中的一样)的RefreshToken
核心代码在JWTUtil的createToken方法中
//使用jwt的api生成token
String token= JWT.create()
.withHeader(map)
.withClaim("uid", user.getId().toString())//私有声明
.withExpiresAt(date)//过期时间
.withIssuedAt(new Date(now))//签发时间
.sign(Algorithm.HMAC256(SECRET));//签名
redisUtil.hset("refreshToken",String.valueOf(user.getId()),Long.valueOf((long) Math.floor(now/1000)), REFRESHTOKENEXPIRE);现在认证时必须AccessToken没被篡改过以及Redis存在所对应的RefreshToken，且RefreshToken时间戳和AccessToken信息中时间戳一致才算认证通过，这样可以做到JWT的可控性，如果重新登录获取了新的AccessToken，旧的AccessToken就认证不了，因为Redis中所存放的的RefreshToken时间戳信息只会和最新的AccessToken信息中携带的时间戳一致，这样每个用户就只能使用最新的AccessToken认证。
核心代码在JWTFilter中的getNewJwtToken方法中
if (!JWTUtil.verify(token) || uid == null) {
throw new AuthenticationException("token认证失效，请重新登陆");
}
String refreshToken = String.valueOf(redisUtil.hget("refreshToken",uid));
String accessToken = JWTUtil.getAccessToken(token);
if (StringUtils.isBlank(refreshToken) || !accessToken.equals(refreshToken)) {
throw new AuthenticationException("token过期，请重新登陆");
}3.token续期
如果用户正在访问我们的网站，突然token过期了，这时用户只能重新登录获取新的token进行访问，这样的用户体验肯定不好。
解决：1. 本身AccessToken的过期时间为5分钟，RefreshToken过期时间为30分钟，当登录后时间过了5分钟之后，当前AccessToken便会过期失效，再次带上AccessToken访问判断是否过期，如果过期，开始判断是否要进行AccessToken刷新，首先redis查询RefreshToken是否存在，以及时间戳和过期AccessToken所携带的时间戳是否一致，如果存在且一致就进行AccessToken刷新。
2. 刷新后新的AccessToken过期时间依旧为5分钟，时间戳为当前最新时间戳，同时也设置RefreshToken中的时间戳为当前最新时间戳，刷新过期时间重新为30分钟过期，最终将刷新的AccessToken设置到在Response的Header中的refreshToken字段返回。
3. 同时前端进行获取替换，下次用新的AccessToken进行访问即可。
核心代码还是在JWTFilter中的getNewJwtToken方法中
//token续期
if (JWTUtil.isJwtExpired(token) && accessToken.equals(refreshToken)) {
//生成新token
User user = new User();
user.setId(Integer.valueOf(uid));
token = JWTUtil.createToken(user);
log.info("token续期成功:" + token);
response.addHeader("refreshToken", token);
response.setHeader("Access-Control-Expose-Headers", "refreshToken");
return token;
}4.redis缓存数据
在MyRealm中用Redis对认证、授权数据进行缓存，不然每次请求都会去查询数据库。文章来源：https://www.toymoban.com/news/detail-457691.html
