An RPC framework based on Netty, ZooKeeper and Spring
中文详情：Chinese Details

• Simple code and framework
• Non-blocking asynchronous call and Synchronous call support
• Long lived persistent connection
• High availability, load balance and failover
• Service Discovery support by ZooKeeper

1. Define an interface:

    public interface HelloService{String hello(String name); String hello(Person person)} 

2. Implement the interface with annotation @RpcService:

    @RpcService(HelloService.class) public class HelloServiceImpl implements HelloService{@Override public String hello(String name){return "Hello! " + name} @Override public String hello(Person person){return "Hello! " + person.getFirstName() + " " + person.getLastName()} } 

3. Run zookeeper

4. Start server:

    RpcBootstrap 

5. Use the client:

    ServiceDiscovery serviceDiscovery = new ServiceDiscovery("127.0.0.1:2181"); final RpcClient rpcClient = new RpcClient(serviceDiscovery); // Sync call HelloService helloService = rpcClient.create(HelloService.class); String result = helloService.hello("World"); // Async call IAsyncObjectProxy client = rpcClient.createAsync(HelloService.class); RPCFuture helloFuture = client.call("hello", "World"); String result = (String) helloFuture.get(3000, TimeUnit.MILLISECONDS);
