JRPC是一个轻量级的java RPC框架。它支持服务注册和发现。

目前它开源了，地址为：https://github.com/dinstone/jrpc。

git clone https://github.com/dinstone/jrpc.git

maven install.

select transport implement,add ‘mina’ or ‘netty’ dependency:

<dependency>
    <groupId>com.dinstone.jrpc</groupId>
    <artifactId>jrpc-transport-mina</artifactId>
    <version>${jrpc.version}</version>
</dependency>

or

<dependency>
    <groupId>com.dinstone.jrpc</groupId>
    <artifactId>jrpc-transport-netty4</artifactId>
    <version>${jrpc.version}</version>
</dependency>

if you need service registry and discovery, please add dependencies :

<dependency>
    <groupId>com.dinstone.jrpc</groupId>
    <artifactId>jrpc-registry-zookeeper</artifactId>
    <version>${jrpc.version}</version>
</dependency>

If you are integrated with Spring, please add dependencies :

<dependency>
    <groupId>com.dinstone.jrpc</groupId>
    <artifactId>jrpc-spring</artifactId>
    <version>${jrpc.version}</version>
</dependency>

For more details, please refer to the example project : jrpc-example

Server server = new Server("localhost", 4444);
ServiceExporter serviceExporter = server.getServiceExporter();
serviceExporter.exportService(HelloService.class, new HelloServiceImpl());

System.in.read();

server.destroy();

Client client = new Client("localhost", 4444);
ServiceImporter serviceImporter = client.getServiceImporter();
HelloService helloService = serviceImporter.importService(HelloService.class);
helloService.sayHello("dinstone");

client.destroy();
