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JWT
1.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>123456
2.2公共工程创建
然后创建一个common工程，其他工程依赖此系统导入JWT相关的依赖

启动服务测试
启动服务
通过Postman来访问测试
根据token信息我们访问其他资源
2.4资源系统创建
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。
接下来我们再创建一个资源服务

编写产品服务配置文件
切记这里只能有公钥地址！
server:port:9002spring:datasource:driver-class-name:com.mysql.jdbc.Driverurl:jdbc:mysql://localhost:3306/srmusername:rootpassword:123456type:com.alibaba.druid.pool.DruidDataSourcemybatis:type-aliases-package:com.dpb.domainmapper-locations:classpath:mapper/*.xmllogging:level:com.dpb:debugrsa:key:pubKeyFile:c:\tools\auth_key\id_key_rsa.pub123456789101112131415161718
编写读取公钥的配置类
packagecom.dpb.config;importcom.dpb.utils.RsaUtils;importlombok.Data;importorg.springframework.boot.context.properties.ConfigurationProperties;importjavax.annotation.PostConstruct;importjava.security.PrivateKey;importjava.security.PublicKey;/***@program:springboot-54-security-jwt-demo*@description:*@author:波波烤鸭*@create:-12-0311:25*/@Data@ConfigurationProperties(prefix="rsa.key")publicclassRsaKeyProperties{privateStringpubKeyFile;privatePublicKeypublicKey;/***系统启动的时候触发*@throwsException*/@PostConstructpublicvoidcreateRsaKey()throwsException{publicKey=RsaUtils.getPublicKey(pubKeyFile);}}1234567891011121314151617181922232425262728293031323334
编写启动类
packagecom.dpb;importcom.dpb.config.RsaKeyProperties;importorg.mybatis.spring.annotation.MapperScan;importorg.springframework.boot.SpringApplication;importorg.springframework.boot.autoconfigure.SpringBootApplication;importorg.springframework.boot.context.properties.EnableConfigurationProperties;/***@program:springboot-54-security-jwt-demo*@description:*@author:波波烤鸭*@create:-12-0317:23*/@SpringBootApplication@MapperScan("com.dpb.mapper")@EnableConfigurationProperties(RsaKeyProperties.class)publicclassApp{publicstaticvoidmain(String[]args){SpringApplication.run(App.class,args);}}123456789101112131415161718192223
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
packagecom.dpb.config;importcom.dpb.filter.TokenVerifyFilter;importcom.dpb.service.UserService;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.context.annotation.Bean;importorg.springframework.context.annotation.Configuration;importorg.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;importorg.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;importorg.springframework.security.config.annotation.web.builders.HttpSecurity;importorg.springframework.security.config.annotation.web.configuration.EnableWebSecurity;importorg.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;importorg.springframework.security.config.http.SessionCreationPolicy;importorg.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;/***@program:springboot-54-security-jwt-demo*@description:*@author:波波烤鸭*@create:-12-0312:41*/@Configuration@EnableWebSecurity@EnableGlobalMethodSecurity(securedEnabled=true)publicclassWebSecurityConfigextendsWebSecurityConfigurerAdapter{@AutowiredprivateUserServiceuserService;@AutowiredprivateRsaKeyPropertiesprop;@BeanpublicBCryptPasswordEncoderpasswordEncoder(){returnnewBCryptPasswordEncoder();}//指定认证对象的来源publicvoidconfigure(AuthenticationManagerBuilderauth)throwsException{auth.userDetailsService(userService).passwordEncoder(passwordEncoder());}//SpringSecurity配置信息publicvoidconfigure(HttpSecurityhttp)throwsException{http.csrf().disable().authorizeRequests()//.antMatchers("/user/query").hasAnyRole("USER").anyRequest().authenticated().and().addFilter(newTokenVerifyFilter(super.authenticationManager(),prop))//禁用掉session.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);}}123456789101112131415161718192223242526272829303132333435363738394041424344454647484950515253545556
去掉“增加自定义认证过滤器”即可！
编写产品处理器
packagecom.dpb.controller;importorg.springframework.security.access.annotation.Secured;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.RestController;/***@program:springboot-54-security-jwt-demo*@description:*@author:波波烤鸭*@create:-12-0311:55*/@RestController@RequestMapping("/user")publicclassUserController{@RequestMapping("/query")publicStringquery(){return"success";}@RequestMapping("/update")publicStringupdate(){return"update";}}123456789101112131415161718192223242526

搞定~
Redis、Kafka或RabbitMQ，哪个更和微服务更般配？JDK 16 即将发布，看完这些新特性，我感觉已经学不动了..Redis 分布式锁使用不当，超卖了100瓶飞天茅台！！！SQL优化最干货总结（最新版）Redis 分布式锁使用不当，超卖了100瓶飞天茅台！！！为什么MySQL不推荐使用 UUID 或者雪花id作为主键？今天，又被Java8的时间库恶心到了，有同感的举手...Docker从入门到干活，看这一篇足矣好文章，我在看
