快速入门

1.添加依赖

<dependencies>
    <dependency>
      <groupId>com.github.applesline</groupId>
      <artifactId>mini-dubbo</artifactId>
      <version>1.0.0</version>
    </dependency>
</dependencies>

2.业务接口定义

package org.applesline.api;

public interface GreetingService {
    String sayHello(String name);
}

---

3.业务接口实现

package org.applesline;

import org.applesline.api.GreetingService;

public class GreetingServiceImpl implements GreetingService {
    public String sayHello(String name) {
        return "hi " + name;
    }
}

---

4.接口与实现类进行绑定

package org.applesline;

import com.google.inject.AbstractModule;
import com.google.inject.Singleton;
import org.applesline.api.GreetingService;

public class ServerConfig extends AbstractModule {
    public void configure() {
        bind(GreetingService.class).to(GreetingServiceImpl.class).in(Singleton.class);
    }
}

---

5.编写服务端程序并注册服务（guice中注册服务，相当于spring的ioc容器）

package org.applesline;

import org.applesline.mini.dubbo.context.RpcContext;
import org.applesline.mini.dubbo.protocol.Protocol;

public class ServiceProvider {

    public static void main(String[] args) {
        // 将服务注册到guice中，默认使用本地zookeeper作为注册中心（127.0.0.1:2181），需要确保本地安装并启动了zk
        RpcContext.setConfiguration(new ServerConfig());
        Protocol protocol = RpcContext.getBean(Protocol.class);
        protocol.export();
    }
}

---

6.编写客户端服务

package org.applesline;

import org.applesline.api.GreetingService;
import org.applesline.mini.dubbo.context.RpcContext;
import org.applesline.mini.dubbo.proxy.ProxyFactory;

public class ServiceConsumer {

    public static void main(String[] args) {
        // 默认使用本地zookeeper作为注册中心（127.0.0.1:2181），需要确保本地安装并启动了zk
        RpcContext.initContext();
        GreetingService greetingService = ProxyFactory.getProxyObject(GreetingService.class);
        System.out.println(greetingService.sayHello("mini-dubbo"));
    }
}

自此便可以愉快的体验mini-dubbo带来的乐趣了
