对阿里的Dubbo进行精简和封装，降低学习、部署和运维的难度，以适应中等规模公司使用.
GoodDubbo只是对Dubbo进行扩展，兼容原来的API和配置方式，扩展部分也仅仅涉及配置和监控部分，对Dubbo业务数据传输部分并未做任何改动和扩展，所以对框架稳定性完全不受影响；
GoodDubbo去除了Dubbo的第三方Registry(zookeeper、redis等)，直接将IP配置在客户端，便于小型项目快捷开发；
Maven项目添加依赖：
<dependency>
<groupId>com.github.goodpaas</groupId>
<artifactId>gooddubbo</artifactId>
<version>0.1.2.snapshot</version>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<version>2.5.3</version>
</dependency>非Maven项目自己下载jar包：gooddubbo.jar dubbo.jar
创建Service，用于远程调用测试：
Service接口:
package com.goodpaas.gooddubbo.demo;
public interface DemoService {
public String sayHello(String name);
public String sayHelloWord(String name);
}
Service实现：
package com.goodpaas.gooddubbo.demo;
public class Demo1ServiceImpl implements DemoService{
@Override
public String sayHello(String name) {
System.out.println("service_1 say hello to "+name);
return "sayHello service_1 has said to "+name;
}
@Override
public String sayHelloWord(String name) {
System.out.println("service_1 say hello world to "+name);
return "sayHelloWord service_1 has said to "+name;
}
}
服务端对外暴露Service:
package com.goodpaas.gooddubbo.demo.simple;
import com.goodpaas.gooddubbo.demo.Demo1ServiceImpl;
import com.goodpaas.gooddubbo.demo.DemoService;
import com.goodpaas.gooddubbo.support.GLocalServerConfig;
import com.goodpaas.gooddubbo.support.GoodSupportFactory;
public class MainService1 {
public static void main(String[] args) throws Exception {
DemoService serviceImpl1 = new Demo1ServiceImpl();
GLocalServerConfig config1 = new GLocalServerConfig();
config1.setProtocolPort(20880);
GoodSupportFactory.exportService(config1, DemoService.class,serviceImpl1);
System.in.read(); // 按任意键退出
}
}
客户端通过代理调用后端Service实现：
package com.goodpaas.gooddubbo.demo.simple;
import com.goodpaas.gooddubbo.demo.DemoService;
import com.goodpaas.gooddubbo.support.GLocalClientConfig;
import com.goodpaas.gooddubbo.support.GoodSupportFactory;
public class MainClient {
public static void main(String[] args) throws Exception {
GLocalClientConfig config = new GLocalClientConfig();
config.addServiceAddress("127.0.0.1:20880");
//多个服务提供方，客户端自动负载均衡
//config.addServiceAddress("127.0.0.1:20881");
DemoService demoService = GoodSupportFactory.createGoodProxy(config, DemoService.class);
while(true){
String res = demoService.sayHello("Tom");
System.out.println(res);
Thread.sleep(3000);
}
}
}
