Spring Authorization Server 实现授权中心

源码地址

当前，Spring Security 对 OAuth 2.0 框架提供了全面的支持。Spring Authorization Server 出现的含义在于替换 Spring Security OAuth，交付 OAuth 2.1 授权框架。 Spring 官方已弃用 Spring Security OAuth。

本文涉及的组件版本如下：

组件 版本
JDK 17
org.springframework.boot 2.6.7
Gradle 7.4.1
spring-security-oauth2-authorization-server 0.2.3 
spring-security-oauth2-authorization-server 项目由 Spring Security 团队领导，**社区驱动**。

本文的目的：

  1. 搭建授权中心示例
  2. fork 当前项目从而免去一些工作

本 demo 的结构

  • root

    • [[#auth-center|授权中心]]
    • [[#user-service|用户服务]]
    • [[#client-gateway|移动端网关]]

OAuth 2.1 支持三种许可类型，[[OAuth 2.1 授权框架#授权码许可]]、[[OAuth 2.1 授权框架#客户端证书许可]]、[[OAuth 2.1 授权框架#刷新令牌许可]]。

  1. 这里的两个 config 中有两个 SecurityFilterChain 类。调用顺序是 authorizationServerSecurityFilterChain、defaultSecurityFilterChain。
  2. registeredClientRepository 用于注册 client。这里的两个 redirectUri 中地址来自于[[#mobile-gateway|移动端网关]]。

public class ResourceServerConfig {  

    @Bean

    SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {

        http.mvcMatcher("/menu/**")

                .authorizeRequests()

                .mvcMatchers("/menu/**").access("hasAuthority('SCOPE_message.read')")

                .and()

                .oauth2ResourceServer()

                .jwt();

        return http.build();

    }

}

定义 menu 路径下的访问权限。

MenuController

@RestController

@RequestMapping("/menu")

public class MenuController {  

    @GetMapping("/list")

    public List<String> list() {

        return List.of("menu1", "menu2", "menu3");

    }

}

application.yml

server:

  port: 9001  

spring:

  application:

    name: user-service

  security:

    oauth2:

      resourceserver:

        jwt:

          issuer-uri: http://localhost:9000

启动服务

资源服务器目前不需要做额外配置，只需要启动即可。

client-gateway

build.gradle

plugins {

    id 'org.springframework.boot' version '2.6.7'

    id 'io.spring.dependency-management' version '1.0.11.RELEASE'

    id 'java'

}  

group = 'com.insight.into.life'

version = '0.0.1-SNAPSHOT'

sourceCompatibility = '17'  

configurations {

    compileOnly {

        extendsFrom annotationProcessor

    }

}  

repositories {

    mavenCentral()

}  

dependencies {

    implementation 'org.springframework.boot:spring-boot-starter-oauth2-client'

    implementation 'org.springframework.boot:spring-boot-starter-web'

    implementation "org.springframework:spring-webflux"

    implementation "io.projectreactor.netty:reactor-netty"

    implementation 'org.springframework.cloud:spring-cloud-starter-openfeign:3.1.2'  

    compileOnly 'org.projectlombok:lombok'

    annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'

    annotationProcessor 'org.projectlombok:lombok'

}  

tasks.named('test') {

    useJUnitPlatform()

}

这里引入 org.springframework:spring-webflux 、io.projectreactor.netty:reactor-netty 的原因在于使用了 WebClient。

config

...

@Component

@Order(Ordered.HIGHEST_PRECEDENCE)

public class LoopbackIpRedirectFilter extends OncePerRequestFilter {  

    @Override

    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {

        if (request.getServerName().equals("localhost") && request.getHeader("host") != null) {

            UriComponents uri = UriComponentsBuilder.fromHttpRequest(new ServletServerHttpRequest(request))

                    .host("127.0.0.1").build();

            response.sendRedirect(uri.toUriString());

            return;

        }

        filterChain.doFilter(request, response);

    }  

}

该配置用于转换地址。将 localhost 转换为 127.0.0.1。

启动服务

在浏览器中输入：http://127.0.0.1:9100

输入账号密码：user1/password，这里的用户在 [[#auth-center#config]] 中配置。得到以下内容：

总结

  1. spring-authorization-server 目前还没有正式发布。文档较少。
  2. 还有一些需要完善的点。比如用户持久化、client 持久化。
  3. 此 demo 还要继续更新，为了能和本文对应，所以对应的 git tag 为 primitive-man 。
