RPC Tutorial Project Documentation

Project Introduction

This is a tutorial project based on gRPC (Remote Procedure Call), demonstrating how to build a complete RPC communication system. The project contains three main components: interface definition, server-side implementation, and client-side invocation.

Project Structure

rpc-lession/
├── rpc-grpc-api/        # Interface definition module
│   ├── HelloProto.java  # Data transfer object definition
│   └── HelloServiceGrpc.java  # Service interface definition
├── rpc-grpc-service/    # Server-side module
│   └── GrpcServer1.java # Service startup class
│   └── HelloServiceImpl.java # Service implementation class
└── rpc-grpc-client/     # Client-side module
    ├── GrpcClient1.java # Client invocation example 1
    └── GrpcClient2.java # Client invocation example 2

Functional Features

  • Supports two RPC method calls:
    • hello: A simple greeting method with a single string parameter
    • hello1: An extended greeting method supporting multiple string parameters
  • Provides complete request/response data model definitions
  • Includes implementations for both synchronous and asynchronous invocation methods

Usage Instructions

Starting the Server

cd rpc-grpc-service
mvn exec:java -Dexec.mainClass="com.lzh.GrpcServer1"

Running the Client

cd rpc-grpc-client
mvn exec:java -Dexec.mainClass="com.lzh.client.GrpcClient1"

Or run the second client example:

mvn exec:java -Dexec.mainClass="com.lzh.client.GrpcClient2"

Dependency Requirements

  • Java 8 or higher
  • Maven 3.x
  • gRPC Java library
  • Protocol Buffers compiler
