【初级教程】—Dubbo的配置及启动

• Tomcat+Dubbo安装

        1.将tomcat的webapps目录下的所有文件清空，讲Dubbo管理控制台的程序dubbo-admin-2.5.3.war放

到webapps中，并且解压命名为ROOT。

 

                 2.配置dubbo.properties

     将以下地址改为你Zookeeper注册的地址。前提：已经安装过Zookeeper。

                 dubbo.registry.address=zookeeper://192.168.137.2:2181

 

   3.启动tomcat

 

浏览：192.168.137.2:8080出现以下界面

相应的配置已经配置好了，接下来开始写代码，看一下dubbo是怎么样在Zookeeper上注册服务的，在此举一个provider的例子：

 

建立一个maven项目，名称：Interfaces

 

建立一个类：

 package com.demo.rpc;
 
 public interface SpeakInterface
 {
        String speak(People people);
 }

再建一个maven项目，名称：provider

 

pom文件：

 

注意：这里在pom文件中引用interface

                            ${project.build.directory}/lib
                        
                    
                
            
        
    
   

在src/main/resources路径下建立META-INF/spring文件夹，建立以下文件

 

Spring-context.xml文件

Spring-dubbo-provider.xml文件

SpeakInterfaceImpl类

import com.demo.rpc.GrowUpInterface;
import com.demo.rpc.People;
import com.demo.rpc.SpeakInterface;
import org.springframework.stereotype.Component;
 
import javax.annotation.Resource;
 
/**
 * 2015/11/8
 */
@Component("speakInterface")
public class SpeakInterfaceImpl implements SpeakInterface {
  /*  @Resource
    private GrowUpInterface growUpInterface;*/
 
    public String speak(People people) {
        return "dubbo return ";
    }
}

启动，出现如下界面，说明服务已经注册上
