RPC BASED ON NETTY Running in some business online.
当前采用简单的在消息体前加上4byte的消息长度值
// 需要先启动一个zookeeper作为服务注册发现中心
// 服务接口
public interface IHello {
`
String say(String hello);
int sum(int a, int b);
int sum(Integer a, Integer b);
}
// 服务实现
public class HelloImpl implements IHello {
public String say(String hello) {
return "return " + hello;
}
public int sum(int a, int b) {
return a + b;
}
public int sum(Integer a, Integer b) {
return a + b * 3;
}
}
// 客户端代码
// beanJavaConfig方式
@Bean
public CountService countService() {
RpcClientWithLB rpcClientWithLB = new RpcClientWithLB("fyes-counter");
rpcClientWithLB.setZkConn("127.0.0.1:2181");
rpcClientWithLB.init();
CountService countService = rpcClientWithLB.newProxy(CountService.class);
return countService;
}
// 服务端发布
// xml配置方式
