Java gRpc，客户端获取io.gRpc.StatusRuntimeException:UNIMPLEMENTED:方法，即使服务器接收并反序列化消息也是如此

Java gRpc，客户端获取io.gRpc.StatusRuntimeException:UNIMPLEMENTED:方法，即使服务器接收并反序列化消息也是如此,java,spring-boot,maven,grpc,Java,Spring Boot,Maven,Grpc,我是gRpc的新手，我正在尝试使用gRpc 1.27.1和protobuf 3.11在Java 11（Spring Boot 2）服务器和Java 8（Spring Boot 1.5）客户端之间使用它 以下是我的设置： 我有一个数据模型库，其中只有1个proto定义文件和maven文件，用于生成客户端和服务器之间共享的java源代码 pom.xml的相关部分： <properties> <maven.compiler.source>1.8</maven

 // Connection with gRpc server
 @PostConstruct
  void init(){
    channel = nSubConnection();
    log.info("Established NSub gRpc connection for address={} with max-retries={}.", nsubServer, nSubMaxRetryAttempts);
    eventBridgeSvcBlockingStub = EventBridgeServiceGrpc.newBlockingStub(channel);
  }

                                .enableRetry()
                                .maxRetryAttempts(nSubMaxRetryAttempts)

                                .build();
  }


// Actual gRpc call
@EventListener
  public void nSubBridge(RfqEvent event){

   //

  }
一切都可以正常编译和启动，当客户端向服务器发出调用时，服务器接收到该调用，并打印出接收到的电子邮件地址，该地址由客户端序列化为protbuf，发送到有效负载中。 然而，消息在服务器上打印出来之后，我从客户端第一次收到一个错误，然后在服务器端收到一个错误

  • 客户端错误：
    • 知道我的客户端代码或设置出了什么问题吗？

    结果是我没有发布服务器代码，这就是问题所在

    我会把我的错误贴在这里，这样其他人就不必花时间在这个愚蠢的错误上：

    @Override
public void newRfqNotification(RfqNotificationEvent request, StreamObserver<RfqNotificationResponse> responseObserver) {
    
    super.newRfqNotification(request, responseObserver);

    
   /*

    My business logic to process the incoming request omitted.

   */

}
    这要求：

    /**
   * Sets unimplemented status for method on given response stream for unary call.
   *
   * @param methodDescriptor of method for which error will be thrown.
   * @param responseObserver on which error will be set.
   */
  public static void asyncUnimplementedUnaryCall(
      MethodDescriptor<?, ?> methodDescriptor, StreamObserver<?> responseObserver) {
    checkNotNull(methodDescriptor, "methodDescriptor");
    checkNotNull(responseObserver, "responseObserver");
    responseObserver.onError(Status.UNIMPLEMENTED
        .withDescription(String.format("Method %s is unimplemented",
            methodDescriptor.getFullMethodName()))
        .asRuntimeException());
  }


    /**
*为一元调用的给定响应流上的方法设置未实现状态。
*
*@param methodDescriptor将为其引发错误的方法。
*@param responseObserver，将在其上设置错误。
*/
公共静态void AsynimplementeDunaryCall(
MethodDescriptor MethodDescriptor，StreamObserver responseObserver）{
checkNotNull（methodDescriptor，methodDescriptor）；
checkNotNull（responseObserver，“responseObserver”）；
responseObserver.onError（Status.UNIMPLEMENTED
.withDescription（String.format（“方法%s未实现”），
methodDescriptor.getFullMethodName（））
.asRuntimeException（））；
}
    因此，客户端接收到
    Status.unplemented
    响应并关闭流，然后导致服务器错误。

    Intellij通过添加super（）浪费了我几个小时的时间！调用super（）是一个常规约定，这就是为什么您/我没有删除它。看起来Intellij遵循了这个惯例——grpc设计用它来表示“未实现”。糟糕。也许grpc必须删除这个浪费人们时间而不是帮助他们的“功能”。
