大家好,又见面了,我是你们的朋友全栈君。

  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>

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

自定义校验token的过滤器

package com.dpb.filter;

import com.dpb.config.RsaKeyProperties;

###编写SpringSecurity的配置类

package com.dpb.config;

import com.dpb.filter.TokenLoginFilter;
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 * @create: 2019-12-03 12:41 */
@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("ADMIN")
                .anyRequest()
                .authenticated()
                .and()
                .addFilter(new TokenLoginFilter(super.authenticationManager(), prop))
                .addFilter(new TokenVerifyFilter(super.authenticationManager(), prop))
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }
}

启动服务测试

启动服务
在这里插入图片描述

通过Postman来访问测试
在这里插入图片描述

在这里插入图片描述

根据token信息我们访问其他资源

在这里插入图片描述

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
在这里插入图片描述

导入相关的依赖

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

        <artifactId>spring-boot-configuration-processor</artifactId>
        <optional>true</optional>
    </dependency>
</dependencies>

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

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 * @create: 2019-12-03 11:25 */
@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);
    }

}

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 * @create: 2019-12-03 17:23 */
@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 * @create: 2019-12-03 12:41 */
@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);
    }
}

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 * @create: 2019-12-03 11:55 */
@RestController
@RequestMapping("/user")
public class UserController { 
   

    @RequestMapping("/query")
    public String query(){ 
   
        return "success";
    }

    @RequestMapping("/update")
    public String update(){ 
   
        return "update";
    }
}

测试

在这里插入图片描述
