springboot grpc

依赖

<!--grpc和spring-boot集成框架,包括grpc-server和grpc-client -->
<dependency>
  <groupId>net.devh</groupId>
  <artifactId>grpc-spring-boot-starter</artifactId>
</dependency>

服务端

配置项

grpc:
  server:
    port: 0
    address:

接口实现类与服务器进行绑定，注解@GrpcService

客户端

配置项

grpc:
  server:
    port: 0
  client:
    #这个名称很重要
    userservice:
      #address: static://localhost:9999
      enable-keep-alive: true
      keep-alive-without-calls: true
      negotiation-type: plaintext

获取stub，注解@GrpcClient，参数要对应配置

三种类型的stub

**newStub**：Creates a new async stub that supports all call types for the service
**newBlockingStub**： Creates a new blocking-style stub that supports unary and streaming output calls on the service（仅支持简单RPC和服务端流式）
**newFutureStub**：Creates a new ListenableFuture-style stub that supports unary calls on the service
