## 简易RPC实现

使用服务名注册，减少注册中心压力，像 spring cloud 注册中心一样，只注册服务名称以及其服务节点地址

### 客户端

+ 服务发现
+ 负载均衡
+ 远程调用
+ 序列化
+ netty 通信

### 服务端
+ 注册服务
+ 序列化
+ 反序列化
+ 反射

客户端接收响应
```bash
response: hello from server张三
response: {"description":"测试","message":"hello from server"}
````

服务器接收到
```bash
 read index:0 write index:483 capacity:483

### 注册中心

这里默认实现使用 zookeeper, zookeepr使用3.5.x,因为 curator 4.x 需要支持 zookeeper 3.5.x
