Spring Boot整合Shiro 权限管理 在前后端分离的SpringBoot项目中集成Shiro权限框架
Spring Boot整合Shiro 权限管理 在前后端分离的SpringBoot项目中集成Shiro权限框架
项目背景
公司在几年前就采用了前后端分离的开发模式,前端所有请求都使用ajax。这样的项目结构在与CAS单点登录等权限管理框架集成时遇到了很多问题,使得权限部分的代码冗长丑陋,CAS的各种重定向也使得用户体验很差,在前端使用vue-router管理页面跳转时,问题更加尖锐。于是我就在寻找一个解决方案,这个方案应该对代码的侵入较少,开发速度快,实现优雅。最近无意中看到springboot与shiro框架集成的文章,在了解了springboot以及shiro的发展状况,并学习了使用方法后,开始在网上搜索前后端分离模式下这两个框架的适应性,在经过测试后发现可行,完全符合个人预期。
解决方案
本文中项目核心包为SpringBoot1.5.9.RELEASE以及shiro-spring 1.4.0,为了加快开发效率,持久化框架使用hibernate-JPA,为增加可靠性,sessionId的管理使用了shiro-redis开源插件,避免sessionId断电丢失,同时使得多端可共享session,项目结构为多模块项目,详见下图。
其中spring-boot-shiro模块为本文重点,该模块包含shiro核心配置,shiro数据源配置以及各种自定义实现,登录相关服务等。该模块在项目中使用时可直接在pom中引用,并在spring-boot-main入口模块中配置相应数据库连接信息即可,且该模块可以在多个项目中复用,避免重复开发。spring-boot-module1为模拟真实项目中的业务模块,可能会有多个。spring-boot-common中包含通用工具类,常量,异常等等。多模块项目的搭建在本文中不作赘述。

spring-boot-shiro模块接口如下图
传统结构项目中,shiro从cookie中读取sessionId以此来维持会话,在前后端分离的项目中(也可在移动APP项目使用),我们选择在ajax的请求头中传递sessionId,因此需要重写shiro获取sessionId的方式。自定义MySessionManager类继承DefaultWebSessionManager类,重写getSessionId方法,代码如下
-
import org.apache.shiro.web.servlet.ShiroHttpServletRequest;
-
import org.apache.shiro.web.session.mgt.DefaultWebSessionManager;
-
import org.apache.shiro.web.util.WebUtils;
-
import org.springframework.util.StringUtils;
-
import javax.servlet.ServletRequest;
-
import javax.servlet.ServletResponse;
-
import java.io.Serializable;
-
/**
-
* Created by Administrator on 2017/12/11.
-
* 自定义sessionId获取
-
*/
-
public class MySessionManager extends DefaultWebSessionManager {
-
private static final String AUTHORIZATION = “Authorization”;
-
private static final String REFERENCED_SESSION_ID_SOURCE = “Stateless request”;
-
public MySessionManager() {
-
super();
-
}
-
-
protected Serializable getSessionId(ServletRequest request, ServletResponse response) {
-
String id = WebUtils.toHttp(request).getHeader(AUTHORIZATION);
-
//如果请求头中有 Authorization 则其值为sessionId
-
if (!StringUtils.isEmpty(id)) {
-
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE, REFERENCED_SESSION_ID_SOURCE);
-
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, id);
-
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID, Boolean.TRUE);
-
return id;
-
} else {
-
//否则按默认规则从cookie取sessionId
-
return super.getSessionId(request, response);
-
}
-
}
-
}
如何配置让shiro执行我们的自定义sessionManager呢?下面看ShiroConfig类。
-

-

-
shiroFilterFactoryBean.setSecurityManager(securityManager);
-
Map<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>();
-
//注意过滤器配置顺序 不能颠倒

public HashedCredentialsMatcher hashedCredentialsMatcher() {
-

在定义的SessionManager的Bean中返回我们的MySessionManager,然后在SecurityManager的Bean中调用setSessionManager(SessionManager sessionManager)方法加载我们的自定义SessionManager。
附上
MyShiroRealm的代码
-
package com.xxx.shiro.config;
-
import com.xxx.shiro.entity.SysPermission;
-
import com.xxx.shiro.entity.SysRole;
-
import com.xxx.shiro.entity.UserInfo;
-
import com.xxx.shiro.service.UserInfoService;
-
import org.apache.shiro.authc.*;
-
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.apache.shiro.util.ByteSource;
-
import javax.annotation.Resource;
-
/**
-
* Created by Administrator on 2017/12/11.
-
* 自定义权限匹配和账号密码匹配
-
*/
-
public class MyShiroRealm extends AuthorizingRealm {
-
-
private UserInfoService userInfoService;
-
-
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
-
// System.out.println(“权限配置–>MyShiroRealm.doGetAuthorizationInfo()”);
-
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
-
UserInfo userInfo = (UserInfo) principals.getPrimaryPrincipal();
-
for (SysRole role : userInfo.getRoleList()) {
-
authorizationInfo.addRole(role.getRole());
-
for (SysPermission p : role.getPermissions()) {
-
authorizationInfo.addStringPermission(p.getPermission());
-
}
-
}
-
return authorizationInfo;
-
}
-
/*主要是用来进行身份认证的,也就是说验证用户输入的账号和密码是否正确。*/
-
-
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token)
-
throws AuthenticationException {
-
// System.out.println(“MyShiroRealm.doGetAuthenticationInfo()”);
-
//获取用户的输入的账号.
-
String username = (String) token.getPrincipal();
-
// System.out.println(token.getCredentials());
-
//通过username从数据库中查找 User对象,如果找到,没找到.
-
//实际项目中,这里可以根据实际情况做缓存,如果不做,Shiro自己也是有时间间隔机制,2分钟内不会重复执行该方法
-
UserInfo userInfo = userInfoService.findByUsername(username);
-
// System.out.println(“—–>>userInfo=”+userInfo);
-
if (userInfo == null) {
-
return null;
-
}
-
if (userInfo.getState() == 1) { //账户冻结
-
throw new LockedAccountException();
-
}
-
SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
-
userInfo, //用户名
-
userInfo.getPassword(), //密码
-
ByteSource.Util.bytes(userInfo.getCredentialsSalt()),//salt=username+salt
-
getName() //realm name
-
);
-
return authenticationInfo;
-
}
-
}
传统项目中,登录成功后应该重定向请求,但在前后端分离项目中,通过ajax登录后应该返回登录状态标志以及相关信息。Web层登录方法代码如下
-
/**
-
* 登录方法
-
* @param userInfo
-
* @return
-
*/
-
-
-
public String ajaxLogin(UserInfo userInfo) {
-
JSONObject jsonObject = new JSONObject();
-
Subject subject = SecurityUtils.getSubject();
-
UsernamePasswordToken token = new UsernamePasswordToken(userInfo.getUsername(), userInfo.getPassword());
-
try {
-
subject.login(token);
-
jsonObject.put(“token”, subject.getSession().getId());
-
jsonObject.put(“msg”, “登录成功”);
-
} catch (IncorrectCredentialsException e) {
-
jsonObject.put(“msg”, “密码错误”);
-
} catch (LockedAccountException e) {
-
jsonObject.put(“msg”, “登录失败,该用户已被冻结”);
-
} catch (AuthenticationException e) {
-
jsonObject.put(“msg”, “该用户不存在”);
-
} catch (Exception e) {
-
e.printStackTrace();
-
}
-
return jsonObject.toString();
-
}
本项目使用SpringMVC框架,可以自行修改使用其他MVC框架。登录成功则返回sessionId作为token给前端存储,前端请求时将该token放入请求头,以Authorization为key,以此来鉴权。如果出现账号或密码错误等异常则返回错误信息。
传统项目中,登出后应重定向请求,到登录界面或其他指定界面,在前后端分离的项目中,我们应该返回json信息。在上面提到的ShiroConfig中配置了默认登录路由
在Web层加入方法
-
/**
-
* 未登录,shiro应重定向到登录界面,此处返回未登录状态信息由前端控制跳转页面
-
* @return
-
*/
-
-
-
public Object unauth() {
-
Map<String, Object> map = new HashMap<String, Object>();
-
map.put(“code”, “1000000”);
-
map.put(“msg”, “未登录”);
-
return map;
-
}
此处简单提示未登录返回状态码,也可自行定义信息。
在项目中,权限相关表可能不在业务库中,因此有必要单独配置权限相关表的数据源。详细配置可以参见《Spring Boot多数据源配置与使用》一文。
Shiro数据源配置代码
-
package com.xxx.shiro.datasource;
-
import java.util.Map;
-
import javax.persistence.EntityManager;
-
import javax.sql.DataSource;
-
import org.springframework.beans.factory.annotation.Autowired;
-
import org.springframework.beans.factory.annotation.Qualifier;
-
import org.springframework.boot.autoconfigure.orm.jpa.JpaProperties;
-
import org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder;
-
import org.springframework.context.annotation.Bean;
-
import org.springframework.context.annotation.Configuration;
-
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
-
import org.springframework.orm.jpa.JpaTransactionManager;
-
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
-
import org.springframework.transaction.PlatformTransactionManager;
-
import org.springframework.transaction.annotation.EnableTransactionManagement;
-
/**
-
* Created by Administrator on 2017/12/11.
-
*/
-
-
-
-
-
-
-
public class ShiroDataSourceConfig {
-
-
private JpaProperties jpaProperties;
-
-
-
private DataSource shiroDataSource;
-
-
public EntityManager shiroEntityManager(EntityManagerFactoryBuilder builder) {
-
return shiroEntityManagerFactory(builder).getObject().createEntityManager();
-
}
-
-
public LocalContainerEntityManagerFactoryBean shiroEntityManagerFactory (EntityManagerFactoryBuilder builder) {
-
return builder
-
.dataSource(shiroDataSource)
-
.properties(getVendorProperties(shiroDataSource))
-
.packages(“com.xxx.shiro.entity”)
-
.persistenceUnit(“shiroPersistenceUnit”)
-
.build();
-
}
-
private Map<String, String> getVendorProperties(DataSource dataSource) {
-
return jpaProperties.getHibernateProperties(dataSource);
-
}
-
-
PlatformTransactionManager shiroTransactionManager(EntityManagerFactoryBuilder builder) {
-
return new JpaTransactionManager(shiroEntityManagerFactory(builder).getObject());
-
}
-
}
IDEA下JpaProperties可能会报错,可以忽略。
入口模块结构如下图
DataSourceConfig中配置了多个数据源的Bean,其中shiro数据源Bean代码
-
/**
-
* shiro数据源
-
* @return
-
*/
-
-
-
-
public DataSource shiroDataSource() {
-
return DataSourceBuilder.create().build();
-
}
ServletInitializer和StartApp为SpringBoot在外部tomcat启动配置,不赘述。
SpringBoot的相关配置在application.yml中,shiro配置代码如下图
Primary为主库配置。当在某个项目中引入spring-boot-shiro模块时,只需要在配置文件中加入shiro数据源及redis的相关配置,并在DataSourceConfig加入shiro数据源Bean即可。
Shiro框架会根据用户登录及权限状态抛出异常,建议使用SpringMVC的全局异常捕获来处理异常,避免重复代码。该项目中代码如下
-
package com.xxx.shiro.config;
-
import com.alibaba.fastjson.support.spring.FastJsonJsonView;
-
import org.apache.shiro.authz.UnauthenticatedException;
-
import org.apache.shiro.authz.UnauthorizedException;
-
import org.springframework.web.servlet.HandlerExceptionResolver;
-
import org.springframework.web.servlet.ModelAndView;
-
import javax.servlet.http.HttpServletRequest;
-
import javax.servlet.http.HttpServletResponse;
-
import java.util.HashMap;
-
import java.util.Map;
-
/**
-
* Created by Administrator on 2017/12/11.
-
* 全局异常处理
-
*/
-
public class MyExceptionHandler implements HandlerExceptionResolver {
-
public ModelAndView resolveException(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception ex) {
-
ModelAndView mv = new ModelAndView();
-
FastJsonJsonView view = new FastJsonJsonView();
-
Map<String, Object> attributes = new HashMap<String, Object>();
-
if (ex instanceof UnauthenticatedException) {
-
attributes.put(“code”, “1000001”);
-
attributes.put(“msg”, “token错误”);
-
} else if (ex instanceof UnauthorizedException) {
-
attributes.put(“code”, “1000002”);
-
attributes.put(“msg”, “用户无权限”);
-
} else {
-
attributes.put(“code”, “1000003”);
-
attributes.put(“msg”, ex.getMessage());
-
}
-
view.setAttributesMap(attributes);
-
mv.setView(view);
-
return mv;
-
}
-
}
该Bean在ShiroConfig中已有注册代码。
至此,shiro框架的集成就结束了。至于shiro框架的使用细节,可以自行查阅相关资料。项目代码本人测试可正常工作,未应用到生产环境,仅供学习交流使用。
