Spring Authorization Server 實現授權中心

Zhang_Xiang發表於2022-05-10

Spring Authorization Server 實現授權中心

當前，Spring Security 對 OAuth 2.0 框架提供了全面的支援。Spring Authorization Server 出現的含義在於替換 Spring Security OAuth，交付 OAuth 2.1 授權框架。 Spring 官方已棄用 ~~Spring Security OAuth~~。

本文涉及的元件版本如下：

元件	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 專案由 Spring Security 團隊領導，**社群驅動**。

本文的目的：

搭建授權中心示例
fork 當前專案從而免去一些工作

本 demo 的結構

root
- [[#auth-center|授權中心]]
- [[#user-service|使用者服務]]
- [[#client-gateway|移動端閘道器]]

OAuth 2.1 支援三種許可型別，[[OAuth 2.1 授權框架#授權碼許可]]、[[OAuth 2.1 授權框架#客戶端證照許可]]、[[OAuth 2.1 授權框架#重新整理令牌許可]]。

                .build();  
    }

這裡的兩個 config 中有兩個 SecurityFilterChain 類。呼叫順序是 authorizationServerSecurityFilterChain、defaultSecurityFilterChain。
registeredClientRepository 用於註冊 client。這裡的兩個 redirectUri 中地址來自於[[#mobile-gateway|移動端閘道器]]。

application.yml

  level:  
    root: INFO  
    org.springframework.web: INFO  
    org.springframework.security: INFO

啟動服務

在瀏覽器中輸入：http://localhost:9000/.well-known/openid-configuration，得到以下內容。

使用者服務在 demo 中的角色是資源伺服器。

config

...
@EnableWebSecurity  
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();  
    }  
}

定義 menu 路徑下的訪問許可權。

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

啟動服務

資源伺服器目前不需要做額外配置，只需要啟動即可。

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()  
}

這裡引入 org.springframework:spring-webflux 、io.projectreactor.netty:reactor-netty 的原因在於使用了 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);  
    }  
  
}

該配置用於轉換地址。將 localhost 轉換為 127.0.0.1。

        return authorizedClientManager;

    private final WebClient webClient;  
    @Value("${user-service.base-uri}")

    @GetMapping("/menus")  
    public String menus(@RegisteredOAuth2AuthorizedClient("client-gateway-authorization-code") OAuth2AuthorizedClient authorizedClient) {  
        return this.webClient  
                .get()  
                .uri(userServiceBaseUri)  
                .attributes(oauth2AuthorizedClient(authorizedClient))  
                .retrieve()  
                .bodyToMono(String.class)  
                .block();  
    }  
  
}

application.yml

user-service:  
  base-uri: http://127.0.0.1:9001/menu/list

啟動服務

在瀏覽器中輸入：http://127.0.0.1:9100

輸入賬號密碼：user1/password，這裡的使用者在 [[#auth-center#config]] 中配置。得到以下內容：

總結

spring-authorization-server 目前還沒有正式釋出。文件較少。
還有一些需要完善的點。比如使用者持久化、client 持久化。
此 demo 還要繼續更新，為了能和本文對應，所以對應的 git tag 為 primitive-man 。
