快速开始(原生)
Api
服务接口 IHelloService.java
package me.stormma.api;
/**
* @author stormma stormmaybin@gmail.com
*/
public interface IHelloService{
StringsayHello(String name);
}
Provider
服务提供者实现 HelloService.java
package me.stormma.provider;
import me.stormma.annoation.Provider;
import me.stormma.api.IHelloService;
/**
* @author stormma stormmaybin@gmail.com
*/
@Provider(interfaceClass = IHelloService.class, version = "1.0.0")
public class HelloServiceimplements IHelloService{
@Override
public String sayHello(String name){
return "hello " + name;
}
}
服务提供者启动类 ServerBootstrap.java
package me.stormma.provider;
import me.stormma.constants.Constants;
import me.stormma.rpc.model.ServerInfo;
import me.stormma.rpc.netty.bootstrap.RpcServer;
import me.stormma.rpc.registry.ServiceRegistry;
import me.stormma.rpc.registry.zk.ZookeeperServiceRegistry;
/**
* @author stormma stormmaybin@gmail.com
*/
public class ServerBootstrap{
public static void main(String... args)throws Exception {
String zkServer = "139.199.27.243:2181";
ServiceRegistry serviceRegistry = new ZookeeperServiceRegistry(zkServer);
ServerInfo serverInfo = new ServerInfo(Constants.DEFAULT_HOST, Constants.DEFAULT_PORT
, Constants.SERVER_DEFAULT_WEIGHT);
RpcServer rpcServer = new RpcServer(serviceRegistry, serverInfo);
rpcServer.start("me.stormma.provider");
}
}
Consumer
服务消费者实现类 ConsumerClient.java
package me.stormma.consumer;
import me.stormma.api.IHelloService;
import me.stormma.rpc.proxy.DefaultProxy;
import me.stormma.rpc.registry.ServiceDiscover;
import me.stormma.rpc.registry.zk.ZookeeperServiceDiscover;
/**
* @author stormma stormmaybin@gmail.com
*/
public class ConsumerClient{
public static void main(String[] args){
String zkServer = "139.199.27.243:2181";
ServiceDiscover serviceDiscover = new ZookeeperServiceDiscover(zkServer);
DefaultProxy proxy = new DefaultProxy(serviceDiscover);
IHelloService helloService = proxy.createProxy(IHelloService.class, "1.0.0");
System.out.println(helloService.sayHello("stormma"));
System.exit(0);
}
}
storm-rpc技术依赖
-
zookeeper, 使用zookeeper进行服务注册与发现(服务名称作为服务提供者启动之后创建zk持久性节点保存, 服务对应的地址创建为临时性节点的内容, 实现动态
发现服务宕机和上线, 临时性节点表示为’host:port$weight’, host:port代表服务地址, weight表示为该服务地址的权重, 用来实现负载均衡, 负载均衡算法参考
dubbo的负载均衡算法, 基于权重的负载均衡算法)
-
netty, 使用netty进行服务之间的网络通信, netty的使用参考<
>这本书。 -
kryo, 使用kryo进行序列化和反序列化。
-
动态代理(本项目提供了原生JDK动态代理和CGLIB来实现的动态代理, 用户可以自行配置使用哪种代理方式), 具体工作流程如: 重写BeanPostProcess来实现
解析Bean的字段是否包含
Reference注解, 如果包含就创建个代理对象注入。
storm-rpc功能点
- 服务注册和发现
- 负载均衡
- 集成spring boot
- 远程调用
- 断线重连(后续增加)
后记
storm-rpc从开始开发到一个版本的推出前前后后经历了一周多, 实现借鉴了dubbo的很多代码, 期待你的加入能让storm-rpc走向完善。
