# NettyRpc

An RPC framework based on Netty, ZooKeeper and Spring  

中文详情：[Chinese Details](http://www.cnblogs.com/luxiaoxun/p/5272384.html)

### Features:

* Simple code and framework

* Service registry/discovery support by ZooKeeper

* High availability, load balance and failover

* Support different load balance strategy

* Support asynchronous/synchronous call

* Support different versions of service

* Support different serializer/deserializer

* Dead TCP connection detecting with heartbeat

### Design:

### How to use (netty-rpc-test)

1. Define an interface:

    ```  

    public interface HelloService { 

        String hello(String name); 

        String hello(Person person);

    }

    ```  

2. Implement the interface with annotation @NettyRpcService:

    ```  

    @NettyRpcService(HelloService.class, version = "1.0")

    public class HelloServiceImpl implements HelloService {

        public HelloServiceImpl(){}

	

        @Override

        public String hello(String name) {

            return "Hello " + name;

        }

        @Override

        public String hello(Person person) {

            return "Hello " + person.getFirstName() + " " + person.getLastName();

        }

    }

    ```  

3. Run zookeeper

   For example: zookeeper is running on 127.0.0.1:2181

4. Start server:

   1. Start server with spring config: RpcServerBootstrap

   2. Start server without spring config: RpcServerBootstrap2

5. Call the service:

    1. Use the client:

    ```  

   	final RpcClient rpcClient = new RpcClient("127.0.0.1:2181");

   		

   	// Sync call

   	HelloService helloService = rpcClient.createService(HelloService.class, "1.0");

   	String result = helloService.hello("World");

   		

   	// Async call

   	RpcService client = rpcClient.createAsyncService(HelloService.class, "2.0");

   	RPCFuture helloFuture = client.call("hello", "World");

   	String result = (String) helloFuture.get(3000, TimeUnit.MILLISECONDS);

	``` 

    2. Use annotation @RpcAutowired:

    ``` 

    public class Baz implements Foo {

        @RpcAutowired(version = "1.0")

        private HelloService helloService1;

           

        @RpcAutowired(version = "2.0")

        private HelloService helloService2;

           

        @Override

        public String say(String s) {

            return helloService1.hello(s);

        }

    }

    ```
