@GrpcClient 为 null spring boot 3

Question

我正在使用 grpc 客户端net.devh.grpc-client-spring-boot-starter

客户：

@Service
public class SystemService {
    @GrpcClient("handyman-client")
    StatusServiceGrpc.StatusServiceBlockingStub handymanClient;

    public VersionResponse getHandymanVersion() {
        return handymanClient.getVersion(Empty.newBuilder().build());
    }
}

应用程序.yaml：

grpc:
  client:
    handyman-client:
      address: static://localhost:8080
      negotiationType: plaintext

在运行时handymanClient是null. 3.0.0尝试了从到 的Spring Boot 版本3.0.2。降低spring boot版本2.7.0解决问题——现在正在创建客户端。

有没有办法让它在 Spring Boot 3 上工作？

构建.gradle：

@Service
public class SystemService {
    @GrpcClient("handyman-client")
    StatusServiceGrpc.StatusServiceBlockingStub handymanClient;

    public VersionResponse getHandymanVersion() {
        return handymanClient.getVersion(Empty.newBuilder().build());
    }
}

基于此问题，您必须在项目中使用以下配置：

import org.springframework.boot.autoconfigure.ImportAutoConfiguration;
import org.springframework.context.annotation.Configuration;

@Configuration
@ImportAutoConfiguration({
        net.devh.boot.grpc.client.autoconfigure.GrpcClientAutoConfiguration.class,
        net.devh.boot.grpc.client.autoconfigure.GrpcClientMetricAutoConfiguration.class,
        net.devh.boot.grpc.client.autoconfigure.GrpcClientHealthAutoConfiguration.class,
        net.devh.boot.grpc.client.autoconfigure.GrpcClientSecurityAutoConfiguration.class,
        net.devh.boot.grpc.client.autoconfigure.GrpcClientTraceAutoConfiguration.class,
        net.devh.boot.grpc.client.autoconfigure.GrpcDiscoveryClientAutoConfiguration.class,

        net.devh.boot.grpc.common.autoconfigure.GrpcCommonCodecAutoConfiguration.class,
        net.devh.boot.grpc.common.autoconfigure.GrpcCommonTraceAutoConfiguration.class,
