sofa-rpc源码阅读(1)-环境搭建

1. 环境搭建

1.1 拷贝源码

git clone https://github.com/sofastack/sofa-rpc.git

1.2 编译源码

在源码目录执行

mvn clean install -DskipTests

注意，安装java的版本为1.8，用java11编译会报错

1.3 运行样例

1.3.1 启动服务器

找到类 com.alipay.sofa.rpc.bolt.start.BoltServerMain 运行main方法

public static void main(String[] args) {
    ApplicationConfig application = new ApplicationConfig().setAppName("test-server");

    ServerConfig serverConfig = new ServerConfig()
        .setPort(22000)
        .setDaemon(false);

    ProviderConfig<HelloService> providerConfig = new ProviderConfig<HelloService>()
        .setInterfaceId(HelloService.class.getName())
        .setApplication(application)
        .setRef(new HelloServiceImpl())
        .setServer(serverConfig)
        .setRegister(false);

    ProviderConfig<EchoService> providerConfig2 = new ProviderConfig<EchoService>()
        .setInterfaceId(EchoService.class.getName())
        .setApplication(application)
        .setRef(new EchoServiceImpl())
        .setServer(serverConfig)
        .setRegister(false);

    providerConfig.export();
    providerConfig2.export();

    LOGGER.warn("started at pid {}", RpcRuntimeContext.PID);
}

结果如下

1.3.2 启动客户端

找到类 com.alipay.sofa.rpc.bolt.start.BoltClientMain 并运行main方法

public static void main(String[] args) throws InterruptedException {
    ApplicationConfig application = new ApplicationConfig().setAppName("test-client");

    ConsumerConfig<HelloService> consumerConfig = new ConsumerConfig<HelloService>()
        .setApplication(application)
        .setInterfaceId(HelloService.class.getName())
        .setDirectUrl("bolt://127.0.0.1:22000")
        .setRegister(false)
        .setTimeout(3000);
    HelloService helloService = consumerConfig.refer();

    ConsumerConfig<EchoService> consumerConfig2 = new ConsumerConfig<EchoService>()
        .setInterfaceId(EchoService.class.getName())
        .setApplication(application)
        .setDirectUrl("bolt://127.0.0.1:22000")
        .setRegister(false)
        .setTimeout(3000);
    EchoService echoService = consumerConfig2.refer();

    consumerConfig2.unRefer();

    LOGGER.warn("started at pid {}", RpcRuntimeContext.PID);

    while (true) {
        try {
            String s = helloService.sayHello("xxx", 22);
            LOGGER.warn("{}", s);
        } catch (Exception e) {
            LOGGER.error(e.getMessage(), e);
        }
        try {
            Thread.sleep(2000);
        } catch (Exception e) {
        }
    }
}

结果如下：
