在Spring Cloud中集成gRPC需要使用grpc-spring-boot-starter,它提供了一系列自动配置类,可以简化gRPC服务的开发和部署。
以下是集成gRPC的步骤:
1. 在pom.xml文件中添加grpc-spring-boot-starter依赖。
```xml
<dependency>
<groupId>net.devh</groupId>
<artifactId>grpc-spring-boot-starter</artifactId>
<version>2.11.0.RELEASE</version>
</dependency>
```
2. 定义gRPC服务接口和实现类。
```java
@GrpcService
public class MyGrpcServiceImpl extends MyGrpcServiceGrpc.MyGrpcServiceImplBase {
@Override
public void sayHello(MyRequest request, StreamObserver<MyResponse> responseObserver) {
String message = "Hello, " + request.getName() + "!";
MyResponse response = MyResponse.newBuilder().setMessage(message).build();
responseObserver.onNext(response);
responseObserver.onCompleted();
}
}
```
其中,@GrpcService注解用于将该类注册为gRPC服务。MyRequest和MyResponse分别是请求和响应的消息类型。
3. 配置gRPC服务端口和协议。
在application.yml文件中添加以下配置:
```yaml
grpc:
server:
port: 9090
negotiationType: plaintext
```
其中,port指定gRPC服务端口,negotiationType指定协议类型。
4. 启动gRPC服务。
在SpringBootApplication类中添加@EnableGrpc注解,启用gRPC服务。
```java
@SpringBootApplication
@EnableGrpc
public class MyApplication {
public static void main(String[] args) {
SpringApplication.run(MyApplication.class, args);
}
}
```
5. 测试gRPC服务。
使用gRPC客户端调用服务方法。
```java
public class MyGrpcClient {
public static void main(String[] args) {
ManagedChannel channel = ManagedChannelBuilder.forAddress("localhost", 9090).usePlaintext().build();
MyGrpcServiceGrpc.MyGrpcServiceBlockingStub blockingStub = MyGrpcServiceGrpc.newBlockingStub(channel);
MyRequest request = MyRequest.newBuilder().setName("Tom").build();
MyResponse response = blockingStub.sayHello(request);
System.out.println(response.getMessage());
channel.shutdown();
}
}
```
其中,ManagedChannel用于创建gRPC连接,MyGrpcServiceGrpc.MyGrpcServiceBlockingStub是服务的客户端存根。
