SpringSecurity实现分布式应用的单点登录

技术栈：SpringBoot + Mybatis + SpringSecurity
程序地址：https://github.com/yaokuku123/spring-security
功能：实现分布式应用的单点登录。

一分布式单点登录的架构

1.1 架构图

image-20210225133423571.png

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A系统，注意A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B系统，这里B系统可以有很多个。

1.2 认证涉及的需要修改的过滤器方法

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。

二环境准备

2.1 构建基于角色的表格

4.3 编写测试类生成rsa的公私钥

作用：用于后续token的生成和解析(执行后，在对应目录下生成公私钥文件

package com.yqj;

import com.yqj.utils.RsaUtils;

import java.security.PrivateKey;
import java.security.PublicKey;

/**

 */

    private String publicKeyPath = "D:\\temp\\auth_key.pub";

    @Test
    public void generateKey() throws Exception {
        RsaUtils.generateKey(publicKeyPath,privateKeyPath,"yorick",2048);

        System.out.println("publicKey: "+publicKey.toString());
        System.out.println("privateKey: "+privateKey.toString());
    }
}

五认证服务模块

5.1 导入pom依赖

<dependencies>
    <dependency>
        <groupId>com.yqj</groupId>
        <artifactId>common</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.6</version>
    </dependency>
    <dependency>

        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.1.2</version>
    </dependency>
</dependencies>

5.2 创建认证服务配置文件

server:
  port: 9001
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql:///security_authority
    username: root
    password: 199748
mybatis:
  type-aliases-package: com.yqj.domain
  configuration:
    map-underscore-to-camel-case: true
logging:
  level:
    com.yqj: debug
yqj:
  key:
    privateKeyPath: D:\\temp\\auth_key
    publicKeyPath: D:\\temp\\auth_key.pub

5.3 公私钥配置类

package com.yqj.config;

import com.yqj.utils.RsaUtils;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

import javax.annotation.PostConstruct;
import java.security.PrivateKey;
import java.security.PublicKey;

/**
 * Copyright(C),2019-2021,XXX公司
 * FileName: RsaKeyProperties
 * Author: yaoqijun
 * Date: 2021/2/25 9:47
 */
@Data
@ConfigurationProperties("yqj.key")
public class RsaKeyProperties {
    private String privateKeyPath;
    private String publicKeyPath;

    private PrivateKey privateKey;
    private PublicKey publicKey;

    @PostConstruct
    public void loadKey() throws Exception {
        privateKey = RsaUtils.getPrivateKey(privateKeyPath);
        publicKey = RsaUtils.getPublicKey(publicKeyPath);
    }
}

5.4 创建认证服务启动类

package com.yqj;

import com.yqj.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;

/**
 * Copyright(C),2019-2021,XXX公司
 * FileName: AuthServerApplication
 * Author: yaoqijun
 * Date: 2021/2/25 9:50
 */
@SpringBootApplication
@MapperScan("com.yqj.mapper")
@EnableConfigurationProperties(RsaKeyProperties.class)
public class AuthServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(AuthServerApplication.class,args);
    }
}

5.5 编写数据库认证相关代码

 */
@Data
public class SysUser implements UserDetails {

    private Integer id;
    private String username;
    private String password;
    private List<SysRole> roles;

    @JsonIgnore
    @Override

六资源服务模块

6.1 配置pom依赖

<dependencies>
    <dependency>
        <groupId>com.yqj</groupId>
        <artifactId>common</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>

    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.1.2</version>
    </dependency>
</dependencies>

6.2 编写产品服务配置文件

server:
  port: 9002
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql:///security_authority
    username: root
    password: 199748
mybatis:
  type-aliases-package: com.yqj.domain
  configuration:
    map-underscore-to-camel-case: true
logging:
  level:
    com.yqj: debug
yqj:
  key:
    publicKeyPath: D:\\temp\\auth_key.pub

6.3 编写读取公钥的配置类

package com.yqj.config;

import com.yqj.utils.RsaUtils;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;

import javax.annotation.PostConstruct;
import java.security.PublicKey;

/**
 * Copyright(C),2019-2021,XXX公司
 * FileName: RsaKeyProperties
 * Author: yaoqijun
 * Date: 2021/2/25 11:04
 */
@Data
@ConfigurationProperties("yqj.key")
public class RsaKeyProperties {
    private String publicKeyPath;
    private PublicKey publicKey;

    @PostConstruct
    public void loadKey() throws Exception {
        publicKey = RsaUtils.getPublicKey(publicKeyPath);
    }
}

6.4 编写启动类

package com.yqj;

import com.yqj.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;

/**
 * Copyright(C),2019-2021,XXX公司
 * FileName: AuthProductApplication
 * Author: yaoqijun
 * Date: 2021/2/25 11:05
 */
@SpringBootApplication
@MapperScan("com.yqj.mapper")
@EnableConfigurationProperties(RsaKeyProperties.class)
public class AuthProductApplication {
    public static void main(String[] args) {
        SpringApplication.run(AuthProductApplication.class,args);
    }
}

6.5 复制认证服务模块的用户对象，角色对象，和校验认证过滤器

image-20210225140140108.png

6.6 SpringSecurity配置类

package com.yqj.config;

import com.yqj.filter.TokenVerifyFilter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
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;

/**
 * Copyright(C),2019-2021,XXX公司
 * FileName: WebSecurityConfig
 * Author: yaoqijun
 * Date: 2021/2/25 11:07
 */
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private RsaKeyProperties prop;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .cors()
                .and()
                .csrf().disable()
                .authorizeRequests()
                .antMatchers("/product").hasAnyRole("USER")
                .anyRequest().authenticated()
                .and()
                .addFilter(new TokenVerifyFilter(authenticationManager(),prop))
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }
}

6.7 编写产品处理器

package com.yqj.controller;

import org.springframework.security.access.annotation.Secured;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Copyright(C),2019-2021,XXX公司
 * FileName: ProductController
 * Author: yaoqijun
 * Date: 2021/2/25 11:20
 */
@RestController
@RequestMapping("/product")
public class ProductController {

    @Secured("ROLE_PRODUCT")
    @GetMapping("/findAll")
    public String findAll(){
        return "9002 success findAll...";
    }
}

七测试

向认证服务器发起认证请求

image-20210225140447861.png

得到认证成功的返回结果，并将token放入header中

image-20210225140630019.png

image-20210225140643756.png

申请访问资源服务中的方法，未携带token，拒绝访问

image-20210225140835517.png

携带token再次申请资源服务的方法

image-20210225140922927.png
