TakinRPC

1. 基于Netty实现远程通信；
2. 服务端使用Guice进行各组件管理和整合；
3. 基于kyro实现高效通用序列化协议；
4. 基于zookeeper实现服务注册；
5. 基于代理与反射使得接口简单易用；
6. 客户端实现随机、一致性哈希、roundbin三种负载均衡算法；
7. 客户端基于hystrix做限流和及时熔断；
8. 对每一次客户端请求使用Countdownlatch做限时保护 ；
9. windows上做的简单性能测试，客户端QPS可达到3500，服务端QPS可达到2W（单机测试，不太准）；

服务端

public class ServerTest {

    public static void main(String[] args) {
        try {
            RPCServer server = new RPCServer();
            server.init(new String[] {}, false);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

     客户端
     
    public static void main(String[] args) {
        try {
            PropertyConfigurator.configure("conf/log4j.properties");
            final Hello hello = ProxyFactory.create(Hello.class, "test", null, null);
            System.out.println("result: " + hello.say("xiaoming"));
            System.out.println("");
            System.out.println("result: " + hello.say("aa"));
