【问题描述】：

我有一个允许用户注册帐户的应用程序。我们的身份验证和用户服务是 UAA，因此我需要能够在没有用户实际在场的情况下与其安全端点进行通信。

如何设置 Spring Cloud Security 以允许从 1 个微服务调用另一个，然后与 UAA 通信以创建用户？

因此，有 2 个主要的微服务在发挥作用。第一个托管 Web 应用程序并将使用 Zuul 的调用转发到第二个微服务。此微服务与 UAA 通信并处理任何其他特定于应用程序的用户请求。

我在第一个微服务 (LandingPage) 上有这个 WebSecurityConfigurerAdapter

@SpringBootApplication
@EnableZuulProxy
@EnableOAuth2Sso
@EnableEurekaClient
@EnableAutoConfiguration
public class LandingPageUiApplication extends WebSecurityConfigurerAdapter {

    public static void main(String[] args) {
        SpringApplication.run(LandingPageUiApplication.class, args);
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().authorizeRequests().anyRequest().permitAll();
    }
}

这在第二个微服务（UserInformation）中：

@SpringBootApplication
@EnableCircuitBreaker
@EnableFeignClients
public class UserInformationServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(UserInformationServiceApplication.class, args);
    }

    @Bean
    public ModelMapper modelMapper() {
        return new ModelMapper();
    }
}

不幸的是，我很难访问第一个微服务上的 REST 端点，也无法将任何内容转发到第二个微服务。我通常会收到 401 响应代码。它们各自的 application.yaml 文件被设置为作为客户端和资源服务器与 UAA 通信

LandingPage Application.yaml

spring:
  application:
    name: Landing Page
  aop:
    proxy-target-class: true

security:
  oauth2:
    client:
      accessTokenUri: http://localhost:8080/uaa/oauth/token
      userAuthorizationUri: http://localhost:8080/uaa/oauth/authorize
      clientId: landing-page
      clientSecret: landing-page-secret
      scope: openid,uaa.admin,uaa.user
    resource:
      userInfoUri: http://localhost:8080/uaa/userinfo

zuul:
  routes:
    users:
      serviceId: USER-INFO-SERVICE
      path: /users/**

server:
  port: 8081

eureka:
  instance:
    hostname: 127.0.0.1
    nonSecurePort: ${server.port}
    leaseRenewalIntervalInSeconds: 10
    metadataMap:
      instanceId: ${spring.application.name}:${server.port}
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
    region: default
    registryFetchIntervalSeconds: 5

和 UserInfoService Application.yaml

server:
  port: 0

security:
  oauth2:
    client:
      clientId: user-info-service
      clientSecret: app-secret
    resource:
      jwt:
        keyUri: http://localhost:8080/uaa/token_key


spring:
  application:
    name: user-info-service
  profiles: development,default
  datasource:
    url: jdbc:h2:mem:AZ;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
    driverClassName: org.h2.Driver
    username: sa
    password:
    database-platform: org.hibernate.dialect.H2Dialect


eureka:
  instance:
    hostname: 127.0.0.1
    nonSecurePort: ${server.port}
    leaseRenewalIntervalInSeconds: 10
    metadataMap:
      instanceId: ${spring.application.name}:${server.port}
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
    region: default
    registryFetchIntervalSeconds: 5

非常感谢任何帮助。

【解决方案1】：

答案是把这个 WebConfigAdapter 设置放在父 MS 中：

    @Configuration
    @EnableOAuth2Sso
    @EnableAutoConfiguration
    protected static class TestConfiguration extends WebSecurityConfigurerAdapter {


        @Override
        public void configure(HttpSecurity http) throws Exception {
            http.csrf().disable().antMatcher("/**")
                .authorizeRequests()
                .anyRequest().permitAll();
        }

    }

以及子 MS 中的以下内容：

    @Configuration
    @Order(-10)
    @EnableOAuth2Client
    @EnableAutoConfiguration
    protected static class TestConfiguration extends WebSecurityConfigurerAdapter {


        @Override
        public void configure(HttpSecurity http) throws Exception {
            http.csrf().disable().anonymous().authenticationFilter(new AnonymousAuthenticationFilter("HALLO")) //allow anonymous access
                    .and()
                    .authorizeRequests()
                    .antMatchers("/**")
                    .permitAll();
        }
    }
