将“微服务网关”与“UAA 服务器”Jhipster 3.5.0 连接起来

Question

我创建了一个 UAA 服务器：

? (1/16) Which *type* of application would you like to create? [BETA] JHipster UAA server (for microservice OAuth2 authentication)

我创建了一个微服务网关：

? (1/16) Which *type* of application would you like to create? Microservice gateway
...
? (6/16) What is the folder path of your UAA application?. ../elseruaa

• 我在“docker-compose”中创建了 docker 容器，并且创建得很好。
• 我必须在网关上添加一些额外的配置才能使用服务器 UAA？

• 我在容器网关中得到以下错误跟踪：

  org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration.setFilterChainProxySecurityConfigurer(org.springframework.security.config.annotation.ObjectPostProcessor,java.util.List) throws java.lang.Exception; nested exception is org.springframework.beans.factory.BeanExpressionException: Expression parsing failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.security.oauth2.provider.token.TokenStore org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfiguration.tokenStore; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tokenStore' defined in class path resource [com/abalia/elser/config/MicroserviceSecurityConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.security.oauth2.provider.token.TokenStore]: Factory method 'tokenStore' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jwtAccessTokenConverter' defined in class path resource [com/abalia/elser/config/MicroserviceSecurityConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter]: Factory method 'jwtAccessTokenConverter' threw exception; nested exception is java.lang.IllegalStateException: No instances available for elseruaa...

非常感谢您的帮助。

我创建了一个 youtube 截屏视频来展示如何使用 UAA 创建 jhipster (3.5.1) 微服务​​。我相信您面临的问题与服务的启动顺序或旧服务未使用 3.5.0+ 代码重新生成有关。正如您在截屏视频和 github 上的源代码中看到的那样，它按原样工作。

我有同样的问题。花了几个小时后，终于通过在 MicroserviceSecurityConfiguration.java 中添加以下内容来修复错误：

注入 org.springframework.cloud.client.discovery.DiscoveryClient

 @Inject
private DiscoveryClient discoveryClient;

在 MicroserviceSecurityConfiguration.java 的任何方法中（我选择 getKeyFromAuthorizationServer 方法），添加以下内容：

discoveryClient.getServices();

Answer 3

Caused by: java.lang.IllegalStateException: No instances available for elseruaa 由 RibbonLoadBalancerClient 报告。

我没有更新我们的 uaa 支持，但您的网关似乎无法在已注册到您的 JHipster 注册表（Eureka 服务器）的 Eureka 客户端列表中找到名为 elseruaa 的服务。所以要么你忘记启动 elseruaa，要么它注册了另一个名字。

更改您的 MobileSecurityConfiguration

@Inject
private DiscoveryClient discoveryClient;

private String getKeyFromAuthorizationServer() {
          List<String> services = discoveryClient.getServices();

          HttpEntity<Void> request = new HttpEntity<Void>(new HttpHeaders());
          String value = (String) this.keyUriRestTemplate
              .exchange("http://uaa/oauth/token_key", HttpMethod.GET, request, Map.class).getBody()
              .get("value");

          return value;
      }

基本上只有一行：

List<String> services = discoveryClient.getServices();

解决这个问题。
