### Pre-check - [x] I am sure that all the content I provide is in English. ### Search before asking - [x] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Dubbo Version dubbo version 3.3.6 and openjdk17 ### Steps to reproduce this issue proto file: ``` syntax = "proto3"; package xxx.grpc.api; option java_multiple_files = true; option java_package = "xxx.grpc.api"; option java_outer_classname = "HelloWorldProto"; service MyService { rpc SayHello (HelloRequest) returns (HelloReply) {} rpc SayHelloServerStream (HelloRequest) returns (stream HelloReply) {} rpc SayHelloClientStream (stream HelloRequest) returns (HelloReply) {} rpc SayHelloBiStream (stream HelloRequest) returns (stream HelloReply) {} } message HelloRequest { string name = 1; } message HelloReply { string message = 1; } ``` Compiling and packaging with grpc-java allows for the use of grpc's backpressure, while compiling with dubbo does not support the following code: ``` @GrpcService public class MyServiceImpl extends MyServiceGrpc.MyServiceImplBase { @Override public StreamObserver<HelloRequest> sayHelloBiStream(StreamObserver<HelloReply> responseObserver) { **ServerCallStreamObserver<HelloReply> serverObs = (ServerCallStreamObserver)responseObserver; serverObs.disableAutoInboundFlowControl();** ........ } } ``` ### What you expected to happen I want to know how to solve it ### Anything else _No response_ ### Are you willing to submit a pull request to fix on your own? - [x] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
