其中與授權服務器依賴不同的是，資源服務器有spring boot版本，版本號會有spring boot進行管理，不需要顯示聲明。

配置資源服務器

1、配置application.yml 文件

spring:
  security:
    oauth2:
      resourceserver:
        jwt:
          issuer-uri: http://localhost:9000

該配置用于指定授權服務器地址，資源服務器將從該地址獲取JWT令牌，并根據(jù)JWT中的屬性進一步自我配置，發(fā)現(xiàn)授權服務器的公鑰、驗證JWT令牌。

2、創(chuàng)建配置類

@EnableWebSecurity(debug = true)
public class ResoruceServerConfig {
    @Bean
    SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .mvcMatchers("/userinfo/**").hasAuthority("SCOPE_userinfo")
                .and()
                .oauth2ResourceServer()
                .jwt();
        return http.build();
    }
}

.mvcMatchers("/userinfo/**").hasAuthority("SCOPE_userinfo")匹配/userinfo/**地址，允許訪問范圍是SCOPE_userinfo
oauth2ResourceServer()定義為資源服務器
jwt()使用JWT令牌

3、創(chuàng)建一個資源接口
/userinfo/用來獲取資源所有者基本信息

@Data
public class UserInfoRes {

    private String username;
}

創(chuàng)建Rest接口

@RestController
public class UserInfoController {

    @GetMapping("/userinfo")
    public UserInfoRes getUserInfo() {
        UserInfoRes userInfoRes = new UserInfoRes();
        userInfoRes.setUsername("阿提說說");
        return userInfoRes;
    }
}

配置客戶端

目前我們客戶端的配置是這樣的：

spring:
  security:
    oauth2:
      client:
        registration:
          gitee:
            client-id: gitee_clientId
            client-secret: gitee_secret
            authorization-grant-type: authorization_code
            redirect-uri: '{baseUrl}/login/oauth2/code/{registrationId}'
            client-name: Gitee
          github:
            client-id: github_clientId
            client-secret: github_secret
          # 自定義
          customize:
            client-id: testClientId
            client-secret: testClientSecret
            authorization-grant-type: authorization_code
            redirect-uri: '{baseUrl}/login/oauth2/code/{registrationId}'
            client-name: Customize
            scope:
              - userinfo
        provider:
          gitee:
            authorization-uri: https://gitee.com/oauth/authorize
            token-uri: https://gitee.com/oauth/token
            user-info-uri: https://gitee.com/api/v5/user
            user-name-attribute: name
          # 自定義
          customize:
            authorization-uri: http://localhost:9000/oauth2/authorize
            token-uri: http://localhost:9000/oauth2/token
            user-info-uri: http://localhost:9000/userinfo
            user-name-attribute: username

這里我們只需要修改customize部分的user-info-uri和 user-name-attribute
調整后配置如下，其他部分跟原來是一樣的。

          customize:
            authorization-uri: http://localhost:9000/oauth2/authorize
            token-uri: http://localhost:9000/oauth2/token
            user-info-uri: http://localhost:8090/userinfo
            user-name-attribute: username

? user-name-attribute的名字，必須在user-info-uri返回的屬性名中存在

整流程體驗

在如上三部分配置完成后，就可以體驗了，啟動spring-security-resource-server、spring-security-authorization-server、spring-security-oauth2-client

瀏覽器訪問地址：http://127.0.0.1:8080/hello，在授權完成后，即跳轉回并顯示結果。

ResourceServer下能看到帶著token的/userinfo請求日志。
