[英]gRpc, client getting io.grpc.StatusRuntimeException: UNIMPLEMENTED: Method even when the message is received and deserialized by the server
我是 gRpc 的新手，我正在嘗試在 Java 11（Spring Boot 2）服務器和使用 gRpc 1.27.1 和 protobuf 3.11 的 Java 8（Spring Boot 1.5）客戶端之間使用它。
這是我的設置：
我有一個只有 1 個 proto 定義文件和 maven 文件的數據模型庫來生成在客戶端和服務器之間共享的 java 源代碼

我的服務現在只有一個非常簡單的 rpc 定義：
syntax = "proto3";
import "E2logData.proto";
option java_multiple_files = true;
package e2log.nsub.bridge;
service EventBridgeService {
rpc RfqNotification( e2log.api.RfqNotificationEvent ) returns ( RfqNotificationResponse ) {}
}
message RfqNotificationResponse{
bool relay_message = 1;
e2log.api.RfqNotificationEvent request = 2;
}
客戶端實現的相關部分在被注釋為 Spring @Component ：
// 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);
}
@VisibleForTesting
ManagedChannel nSubConnection() {
return ManagedChannelBuilder.forTarget(nsubServer )
.enableRetry()
.maxRetryAttempts(nSubMaxRetryAttempts)
.usePlaintext() // for now until it works
.build();
}
// Actual gRpc call
@EventListener
public void nSubBridge(RfqEvent event){
val wireEvent = rfqEventMapper.map(event);
val resp = eventBridgeSvcBlockingStub.rfqNotification( wireEvent);
//
System.err.println(resp);
}
一切都編譯並啟動得很好，當客戶端調用服務器時，服務器收到調用並打印出接收到的電子郵件地址，該地址在客戶端序列化為 protbuf 的有效負載中發送。 但是，在服務器上打印出消息后，我從客戶端 1 收到錯誤消息，然后在服務器端收到錯誤消息。

知道我的客戶端代碼或設置出了什么問題嗎？
事實證明，我沒有發布我的服務器代碼，這就是問題所在。
我將在這里發布我的錯誤，以便其他人不必花時間解決這個愚蠢的錯誤：
@Override
public void newRfqNotification(RfqNotificationEvent request, StreamObserver<RfqNotificationResponse> responseObserver) {
super.newRfqNotification(request, responseObserver);
/*
My business logic to process the incoming request omitted.
*/
}
上面對super.newRfqNotification()調用是在我調用 IntelliJ 的[Override Methods... ^O]為我創建模板方法以填充業務邏輯時創建的。
我以某種方式開始編寫我的業務邏輯而不刪除對 super 的調用，這在許多情況下是好的，但在這種情況下是災難性的。 那么發生的情況是super方法正常處理，向客戶端發送應答，表示該方法尚未實現，繼續調用super()后編寫的業務邏輯。 請參閱下面的實現：
生成方法（超級）：
/**
*/
public void newRfqNotification(e2log.api.RfqNotificationEvent request,
io.grpc.stub.StreamObserver<e2log.nsub.bridge.RfqNotificationResponse> responseObserver) {
asyncUnimplementedUnaryCall(getNewRfqNotificationMethod(), responseObserver);
}
其中調用：
/**
* 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());
}
然后客戶端收到Status.UNIPLEMENTED響應並關閉流，然后導致服務器錯誤。
