SocketRpcClient实现

发送请求RpcReq到服务端

SocketRpcServer实现

接受客户端的请求, 并返回数据RpcResp

处理客户端请求

调用对应实现类的方法, 获取结果

• RpcReqHandler

服务发布与注册

{
    "com.pig.api.UserService + 1.0 + common": new CommonUserServiceImpl1(),
    "com.pig.api.UserService + 2.0 + common": new CommonUserServiceImpl2(),
    "com.pig.api.UserService + 1.0 + admin": new AdminUserServiceImpl1(),
    "com.pig.api.UserService + 2.0 + admin": new AdminUserServiceImpl2(),
}

实现ServiceProvider

多线程请求处理

SocketReqHandler

• 忘记调用shutdownHookUtils了

动态代理实现发送请求

• 静态代理

• 动态代理 (aop)

• • jdk动态代理 (被代理类必须实现接口, 动态生成被代理类接口的实现类)

• • cglib动态代理 (动态生成被代理类的子类)

RPC - Netty+Zookeeper实现

Zookeeper实现服务注册

Zookeeper使用

<dependency>
    <groupId>org.apache.curator</groupId>

    <artifactId>curator-recipes</artifactId>

    <version>4.2.0</version>

</dependency>

zookeeper本地缓存

ZkServiceProvider
