发出gRPCJava客户端发送请求

Question

我有这个代码：

ManagedChannel channel = ManagedChannelBuilder.forAddress("localhost", 9090).usePlaintext().build();
SentenceClassificationServiceGrpc.SentenceClassificationServiceBlockingStub SentenceClassificationStub = SentenceClassificationServiceGrpc.newBlockingStub(channel);

SentenceClassificationRequest request = SentenceClassificationRequest.newBuilder().setDocument("hey").setThreshold(1);
SentenceClassificationResponse response = SentenceClassificationStub.classification(request);

我一直在犯这样的错误：

java：不兼容的类型：com。应用句子分类请求。无法将生成器转换为com。应用句子分类请求

我已经使用Maven插件生成了gRPC Java文件。在看了多个例子后，我不确定我的问题是什么。

Answer 1

解决方案

您忘记构建SentenceClassificationRequest，当前正在分配SentenceClassificationRequest。生成器到语句ClassificationRequest

再加上。build（）到生成器的末尾

SentenceClassificationRequest request = SentenceClassificationRequest.newBuilder().setDocument("hey").setThreshold(1).build();
