dubbo入门和dubbo-admin部署监控

1.环境搭建:
需要用到tomcat7+zookeeper-3.4.6+dubbo-admin-2.5.4-SNAPSHOT.war+eclipse4.*+maven

</build></project>

2.部署dubbo-admin-2.5.4-SNAPSHOT.war
解压之后将所有文件放到tomcat\webapps\ROOT下面
这里写图片描述

修改dubbo.properties

dubbo.registry.address=zookeeper://127.0.0.1:2181dubbo.admin.root.password=rootdubbo.admin.guest.password=guest

在启动tomcat之前先启动zookeeper-3.4.6

这里写图片描述

启动成功之后,启动tomcat.然后访问http://localhost:8080/

这里写图片描述

3.这样dubbo-admin就部署完成了

4.HelloWorld入门案例
直接上代码

package com.ssm.dubbo.service;public interface HelloWorld {    String hello(String name);}

package com.ssm.dubbo.service.impl;import com.ssm.dubbo.service.HelloWorld;public class HelloWorldImpl implements HelloWorld {    @Override    public String hello(String name) {        return "dubbo远程接口服务调用了----" + name ;    }}

客户端和服务端的核心配置文件:

dubbo_provider.xml

<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"        xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"          xsi:schemaLocation="http://www.springframework.org/schema/beans                             http://www.springframework.org/schema/beans/spring-beans.xsd                             http://code.alibabatech.com/schema/dubbo                             http://code.alibabatech.com/schema/dubbo/dubbo.xsd ">          <dubbo:application name="hello-world" />         <dubbo:registry address="127.0.0.1:2181" protocol="zookeeper"/>         <dubbo:protocol name="dubbo" port="20880" />                          <bean id="helloWorldService" class="com.ssm.dubbo.service.impl.HelloWorldImpl" />          <dubbo:service interface="com.ssm.dubbo.service.HelloWorld" ref="helloWorldService" executes="10" /></beans>

dubbo_consumer.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"    xsi:schemaLocation="http://www.springframework.org/schema/beans                         http://www.springframework.org/schema/beans/spring-beans.xsd                          http://code.alibabatech.com/schema/dubbo                            http://code.alibabatech.com/schema/dubbo/dubbo.xsd">    <dubbo:application name="consumer-of-helloworld-app" />    <dubbo:registry address="zookeeper://127.0.0.1:2181" />    <dubbo:reference id="helloWorldService" interface="com.ssm.dubbo.service.HelloWorld" /></beans>

5.开始测试
DubboProviderTest

package com.ssm.dubbo.test;import java.io.IOException;import org.springframework.context.support.ClassPathXmlApplicationContext;/** * 服务启动者 * @author 353654 * */public class DubboProviderTest {    public static void main(String[] args) throws IOException {        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "dubbo_provider.xml" });        context.start();        System.out.println("Press any key to exit.");        System.in.read();    }}

启动执行服务提供者.之后观察dubbo-admin
这里写图片描述

这里写图片描述

DubboConsumerTest

package com.ssm.dubbo.test;import java.io.IOException;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.ssm.dubbo.service.HelloWorld;public class DubboConsumerTest implements Runnable{    @Override    public void run() {        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "dubbo_consumer.xml" });        context.start();        context.getBean("helloWorldService");        HelloWorld helloWorld = (HelloWorld) context.getBean("helloWorldService");        String hello = helloWorld.hello("小明");        System.out.println(hello);        System.out.println("执行完毕");    }    public static void main(String[] args) {        new Thread(new DubboConsumerTest()).start();        System.out.println("Press any key to exit.");        try {            System.in.read();        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }}

执行服务消费者

6.简单粗暴,跟平时接口没什么区别.还能与spring集成.
