gRPC文章系列

SpringBoot下的gRPC相比较C++下的要容易多了，只要把gRPC相关依赖和protobuf插件引入，剩下的就是点击鼠标了。

环境

Idea 2018.3
Windows 7
SpringBoot 2.1.2
Gradle 4.8

示例项目仓库

build.gradle配置

首先是引入protobuf gradle插件用来编译proto

plugins {
    id 'org.springframework.boot' version '2.1.2.RELEASE'
    id 'java'
    // ASSUMES GRADLE 2.12 OR HIGHER. Use plugin version 0.7.5 with earlier gradle versions
    id 'com.google.protobuf' version '0.8.8'
    // Generate IntelliJ IDEA's .idea & .iml project files
    id 'idea'
}

定义grpc、protobuf的版本号变量

// updating the version in our release process.
def grpcVersion = '1.27.0' // CURRENT_GRPC_VERSION
def protobufVersion = '3.11.2'
def protobufJavaUtilVersion = '3.11.3'
def protocVersion = protobufVersion

引入gRPC项目的基础依赖

    implementation "io.grpc:grpc-protobuf:${grpcVersion}"
    implementation "io.grpc:grpc-stub:${grpcVersion}"
    compileOnly "javax.annotation:javax.annotation-api:1.2"

    // examples/advanced need this for JsonFormat
    implementation "com.google.protobuf:protobuf-java-util:${protobufJavaUtilVersion}"

    runtimeOnly "io.grpc:grpc-netty-shaded:${grpcVersion}"

    testImplementation "io.grpc:grpc-testing:${grpcVersion}"

配置protobuf gradle插件

protobuf {
    protoc { artifact = "com.google.protobuf:protoc:${protocVersion}" }
    plugins {
        grpc { artifact = "io.grpc:protoc-gen-grpc-java:${grpcVersion}" }
    }
    generateProtoTasks {
        all()*.plugins { grpc {} }
    }
}
