##HRPC Structure

##Service Registry

##Server Tutorial

#####1. Spring configuration

    <!--扫描需求发布的服务所在的包-->
    <context:component-scan base-package="com.yingjun.rpc.service.impl"/>
    <context:property-placeholder location="classpath:system.properties"/>

    <!--服务端配置-->
    <bean id="rpcServer" class="com.yingjun.rpc.server.RPCServer">
        <constructor-arg name="zookeeper" value="${zookeeper.address}"/>
        <constructor-arg name="serverAddress" value="${server.address}"/>
    </bean>
</beans>

#####2. Service interfacne public interface UserService { public User getUser(String phone); public User updateUser(User user); }

#####3. Provide rpc service @HRPCService(UserService.class) public class UserServiceImpl implements UserService {

    @Override
    public User getUser(String phone) {
        User user =new User(111,"yingjun",phone);
        return user;
    }

    @Override
    public User updateUser(User user) {
        user.setName("yingjun@update");
        return user;
    }
}

##Client Tutorial #####1. Spring configuration

    <context:annotation-config/>
    <context:property-placeholder location="classpath:system.properties"/>
    <!--客户端配置-->
    <bean id="rpcClient" class="com.yingjun.rpc.client.RPCClient">
        <constructor-arg name="zookeeper" value="${zookeeper.address}"/>
        <!--订阅需要用到的接口-->
        <constructor-arg name="interfaces">
            <list>
                <value>com.yingjun.rpc.service.OrderService</value>
                <value>com.yingjun.rpc.service.UserService</value>
                <value>com.yingjun.rpc.service.GoodsService</value>
            </list>
        </constructor-arg>
    </bean>

</beans>

#####2. Synchronous invoking UserService userService = rpcClient.createProxy(UserService.class); User user1 = userService.getUser("188888888"); logger.info("result:" + user1.toString());

#####3. Asynchronous invoking AsyncRPCProxy asyncProxy = rpcClient.createAsyncProxy(UserService.class); asyncProxy.call("getUser", new AsyncRPCCallback() { @Override public void success(Object result) { logger.info("result:" + result.toString()); }

     @Override
     public void fail(Exception e) {
         logger.error("result:" + e.getMessage());
     }
 }, "188888888");
