Proto文件定义与代码生成3.1 获取proto文件首先需要获取Qwen3-32B服务的proto定义文件。假设我们有一个名为qwen_service.proto的文件内容如下syntax proto3; package qwen.service; service QwenService { rpc GenerateText (TextRequest) returns (TextResponse) {} rpc StreamGenerateText (TextRequest) returns (stream TextResponse) {} } message TextRequest { string prompt 1; int32 max_length 2; float temperature 3; } message TextResponse { string generated_text 1; bool is_finished 2; }3.2 生成Java代码使用protobuf编译器生成Java代码。可以通过Maven插件实现build plugins plugin groupIdorg.xolstice.maven.plugins/groupId artifactIdprotobuf-maven-plugin/artifactId version0.6.1/version configuration protocArtifactcom.google.protobuf:protoc:3.19.2:exe:${os.detected.classifier}/protocArtifact pluginIdgrpc-java/pluginId pluginArtifactio.grpc:protoc-gen-grpc-java:1.42.1:exe:${os.detected.classifier}/pluginArtifact /configuration executions execution goals goalcompile/goal goalcompile-custom/goal /goals /execution /executions /plugin /plugins /build执行mvn compile命令后生成的代码将位于target/generated-sources/protobuf目录下。4. gRPC客户端实现4.1 基础客户端配置创建一个gRPC客户端管理类import io.grpc.ManagedChannel;

} Bean public QwenServiceGrpc.QwenServiceBlockingStub qwenServiceBlockingStub(ManagedChannel channel) { return QwenServiceGrpc.newBlockingStub(channel); } Bean public QwenServiceGrpc.QwenServiceStub qwenServiceAsyncStub(ManagedChannel channel) { return QwenServiceGrpc.newStub(channel); } }4.2 同步调用实现import qwen.service.QwenServiceGrpc; import qwen.service.QwenServiceProto.TextRequest; import qwen.service.QwenServiceProto.TextResponse; import org.springframework.stereotype.Service; Service public class QwenGrpcService { private final QwenServiceGrpc.QwenServiceBlockingStub blockingStub;

TextResponse response blockingStub.generateText(request); return response.getGeneratedText(); } }4.3 流式调用实现import io.grpc.stub.StreamObserver; import qwen.service.QwenServiceGrpc; import qwen.service.QwenServiceProto.TextRequest; import qwen.service.QwenServiceProto.TextResponse; import org.springframework.stereotype.Service; import java.util.concurrent.CountDownLatch; import java.util.concurrent.TimeUnit; import java.util.function.Consumer; Service public class QwenStreamService { private final QwenServiceGrpc.QwenServiceStub asyncStub; public QwenStreamService(QwenServiceGrpc.QwenServiceStub asyncStub) { this.asyncStub asyncStub; } public void streamGenerateText(String prompt, int maxLength, float temperature, ConsumerString textConsumer) throws InterruptedException { TextRequest request TextRequest.newBuilder() .setPrompt(prompt) .setMaxLength(maxLength) .setTemperature(temperature) .build(); CountDownLatch latch new CountDownLatch(1); asyncStub.streamGenerateText(request, new StreamObserverTextResponse() { Override public void onNext(TextResponse response) { textConsumer.accept(response.getGeneratedText()); } Override public void onError(Throwable t) { t.printStackTrace(); latch.countDown(); } Override public void onCompleted() { latch.countDown(); } }); latch.await(5, TimeUnit.MINUTES); } }5. 连接池与性能优化5.1 连接池配置对于生产环境建议使用连接池管理gRPC通道import io.grpc.ManagedChannel;
