原文链接:单点登录解决方案,用这个真棒! (qq.com)
通过前面几天文章我们详细的介绍了SpringSecurity的使用,本文我们来看下,结合JWT来实现单点登录操作。
一、什么是单点登陆单点登录(Single Sign On),简称为 SSO,是目前比较流行的企业业务整合的解决方案之一。SSO的定义是在多个应用系统中,用户只需要登录一次就可以访问所有相互信任的应用系统
二、简单的运行机制单点登录的机制其实是比较简单的,用一个现实中的例子做比较。某公园内部有许多独立的景点,游客可以在各个景点门口单独买票。
对于需要游玩所有的景点的游客,这种买票方式很不方便,需要在每个景点门口排队买票,钱包拿 进拿出的,容易丢失,很不安全。
于是绝大多数游客选择在大门口买一张通票(也叫套票),就可以玩遍所有的景点而不需要重新再买票。他们只需要在每个景点门 口出示一下刚才买的套票就能够被允许进入每个独立的景点。
单点登录的机制也一样,如下图所示,

用户认证: 这一环节主要是用户向认证服务器发起认证请求,认证服务器给用户返回一个成功的令牌token,主要在认证服务器中完成,即图中的认证系统,注意认证系统只能有一个。
身份校验: 这一环节是用户携带token去访问其他服务器时,在其他服务器中要对token的真伪进行检验,主要在资源服务器中完成,即图中的应用系统2 3
三、JWT介绍概念说明
从分布式认证流程中,我们不难发现,这中间起最关键作用的就是token,token的安全与否,直接关系到系统的健壮性,这里我们选择使用JWT来实现token的生成和校验。
JWT,全称JSON Web Token,官网地址https://jwt.io,是一款出色的分布式身份校验方案。可以生成token,也可以解析检验token。
JWT生成的token由三部分组成:
- 头部:主要设置一些规范信息,签名部分的编码格式就在头部中声明。
- 载荷:token中存放有效信息的部分,比如用户名,用户角色,过期时间等,但是不要放密码,会泄露!
- 签名:将头部与载荷分别采用base64编码后,用“.”相连,再加入盐,最后使用头部声明的编码类型进行编码,就得到了签名。
JWT生成token的安全性分析
从JWT生成的token组成上来看,要想避免token被伪造,主要就得看签名部分了,而签名部分又有三部分组成,其中头部和载荷的base64编码,几乎是透明的,毫无安全性可言,那么最终守护token安全的重担就落在了加入的盐上面了!
试想:如果生成token所用的盐与解析token时加入的盐是一样的。岂不是类似于中国人民银行把人民币防伪技术公开了?大家可以用这个盐来解析token,就能用来伪造token。这时,我们就需要对盐采用非对称加密的方式进行加密,以达到生成token与校验token方所用的盐不一致的安全效果!
非对称加密RSA介绍
基本原理: 同时生成两把密钥:私钥和公钥,私钥隐秘保存,公钥可以下发给信任客户端
- 私钥加密,持有私钥或公钥才可以解密
- 公钥加密,持有私钥才可解密
优点: 安全,难以破解
缺点: 算法比较耗时,为了安全,可以接受
历史: 三位数学家Rivest、Shamir 和 Adleman 设计了一种算法,可以实现非对称加密。这种算法用他们三个人的名字缩写:RSA。
四、SpringSecurity整合JWT1.认证思路分析SpringSecurity主要是通过过滤器来实现功能的!我们要找到SpringSecurity实现认证和校验身份的过滤器!
回顾集中式认证流程
用户认证:使用UsernamePasswordAuthenticationFilter过滤器中attemptAuthentication方法实现认证功能,该过滤器父类中successfulAuthentication方法实现认证成功后的操作。
身份校验:使用BasicAuthenticationFilter过滤器中doFilterInternal方法验证是否登录,以决定能否进入后续过滤器。
分析分布式认证流程
用户认证:
由于分布式项目,多数是前后端分离的架构设计,我们要满足可以接受异步post的认证请求参数,需要修改UsernamePasswordAuthenticationFilter过滤器中attemptAuthentication方法,让其能够接收请求体。
另外,默认successfulAuthentication方法在认证通过后,是把用户信息直接放入session就完事了,现在我们需要修改这个方法,在认证通过后生成token并返回给用户。
身份校验:
原来BasicAuthenticationFilter过滤器中doFilterInternal方法校验用户是否登录,就是看session中是否有用户信息,我们要修改为,验证用户携带的token是否合法,并解析出用户信息,交给SpringSecurity,以便于后续的授权功能可以正常使用。
2.具体实现为了演示单点登录的效果,我们设计如下项目结构

2.1父工程创建
因为本案例需要创建多个系统,所以我们使用maven聚合工程来实现,首先创建一个父工程,导入springboot的父依赖即可
- <parent>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-starter-parent</artifactId>
- <version>2.1.3.RELEASE</version>
- <relativePath/>
- </parent>
复制代码
然后创建一个common工程,其他工程依赖此系统

说明
资源服务可以有很多个,这里只拿产品服务为例,记住,资源服务中只能通过公钥验证认证。不能签发token!创建产品服务并导入jar包根据实际业务导包即可,咱们就暂时和认证服务一样了。

编写产品服务配置文件
切记这里只能有公钥地址!
- server:
- port: 9002
- spring:
- datasource:
- driver-class-name: com.mysql.jdbc.Driver
- url: jdbc:mysql://localhost:3306/srm
- username: root
- password: 123456
- type: com.alibaba.druid.pool.DruidDataSource
- mybatis:
- type-aliases-package: com.dpb.domain
- mapper-locations: classpath:mapper/*.xml
- logging:
- level:
- com.dpb: debug
- rsa:
- key:
- pubKeyFile: c:\tools\auth_key\id_key_rsa.pub
复制代码
编写读取公钥的配置类
- package com.dpb.config;
- import com.dpb.utils.RsaUtils;
- import lombok.Data;
- import org.springframework.boot.context.properties.ConfigurationProperties;
- import javax.annotation.PostConstruct;
- import java.security.PrivateKey;
- import java.security.PublicKey;
- /**
- * @program: springboot-54-security-jwt-demo
- * @description:
- * @author: 波波烤鸭
- */
- @Data
- @ConfigurationProperties(prefix = "rsa.key")
- public class RsaKeyProperties {
- private String pubKeyFile;
- private PublicKey publicKey;
- /**
- * 系统启动的时候触发
- * @throws Exception
- */
- @PostConstruct
- public void createRsaKey() throws Exception {
- publicKey = RsaUtils.getPublicKey(pubKeyFile);
- }
- }
复制代码
编写启动类
- package com.dpb;
- import com.dpb.config.RsaKeyProperties;
- import org.mybatis.spring.annotation.MapperScan;
- import org.springframework.boot.SpringApplication;
- import org.springframework.boot.autoconfigure.SpringBootApplication;
- import org.springframework.boot.context.properties.EnableConfigurationProperties;
- /**
- * @program: springboot-54-security-jwt-demo
- * @description:
- * @author: 波波烤鸭
- */
- @SpringBootApplication
- @MapperScan("com.dpb.mapper")
- @EnableConfigurationProperties(RsaKeyProperties.class)
- public class App {
- public static void main(String[] args) {
- SpringApplication.run(App.class,args);
- }
- }

复制认证服务中,用户对象,角色对象和校验认证的接口
复制认证服务中的相关内容即可
复制认证服务中SpringSecurity配置类做修改
- package com.dpb.config;import com.dpb.filter.TokenVerifyFilter;import com.dpb.service.UserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;import org.springframework.security.config.annotation.web.builders.HttpSecurity;import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;import org.springframework.security.config.http.SessionCreationPolicy;import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;/** * @program: springboot-54-security-jwt-demo * @description: * @author: 波波烤鸭 */@Configuration@EnableWebSecurity@EnableGlobalMethodSecurity(securedEnabled=true)public class WebSecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private UserService userService; @Autowired private RsaKeyProperties prop; @Bean public BCryptPasswordEncoder passwordEncoder(){ return new BCryptPasswordEncoder(); } //指定认证对象的来源 public void configure(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(userService).passwordEncoder(passwordEncoder()); } //SpringSecurity配置信息 public void configure(HttpSecurity http) throws Exception { http.csrf() .disable() .authorizeRequests() //.antMatchers("/user/query").hasAnyRole("USER") .anyRequest() .authenticated() .and() .addFilter(new TokenVerifyFilter(super.authenticationManager(), prop)) // 禁用掉session .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS); }}<img width="15" _height="15" src="data:image/gif;base64,R0lGODlhAQABAPABAP///wAAACH5BAEKAAAALAAAAAABAAEAAAICRAEAOw==" border="0" alt="">

去掉“增加自定义认证过滤器”即可!
编写产品处理器
- package com.dpb.controller;import org.springframework.security.access.annotation.Secured;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;/** * @program: springboot-54-security-jwt-demo * @description: * @author: 波波烤鸭 */@RestController@RequestMapping("/user")public class UserController { @RequestMapping("/query") public String query(){ return "success"; } @RequestMapping("/update") public String update(){ return "update"; }}<img width="15" _height="15" src="data:image/gif;base64,R0lGODlhAQABAPABAP///wAAACH5BAEKAAAALAAAAAABAAEAAAICRAEAOw==" border="0" alt="">
