springmvc整合dubbo分布式系统的搭建demo

 

四个步骤 

1 搭建zookeeper消息中心 

2 搭建dubbo服务端代码 

3 写dubbo客户端代码 

4 dubbo提供的dubbo-admin-2.5.4.war 管理控制台 

一，搭建zookeeper

1 下载zookeeper安装文件 
    zookeeper-3.3.6.tar.gz 
   这里提供一个百度网盘的下载地址http://pan.baidu.com/s/1gexxfvP 

2  执行命令 tar zxvf zookeeper-3.4.6.tar.gz 解压, 

3 到 zookeeper-3.3.6/conf 目录下 

   把zoo_sample.cfg 复制一份为zoo.cfg,作为默认配置文件

4 配置说明 

tickTime：这个时间是作为 Zookeeper 服务器之间或客户端与服务器之间维持心跳的时间间隔，也就是每个 tickTime 时间就会发送一个心跳。 
dataDir：顾名思义就是 Zookeeper 保存数据的目录，默认情况下，Zookeeper 将写数据的日志文件也保存在这个目录里。 
clientPort：这个端口就是客户端连接 Zookeeper 服务器的端口，Zookeeper 会监听这个端口，接受客户端的访问请求。 

我的配置: 端口2181是默认配置

 

 

5 在zookper-3.3.6/bin目录下执行 

    ./zkServer.sh start 启动zookeeper

 

6 验证zookeeper是否启动 

     使用netstat -lpn | grep 2181 
     如果有端口号, 说明已经启动

 

 

二 DubboServer 工程

1，pom.xml

2.web.xml

 3,spring和dubbo配置文件

 xml version="1.0" encoding="UTF-8"?>
 <beans:beans xmlns="http://www.springframework.org/schema/mvc"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns:beans="http://www.springframework.org/schema/beans"
     xmlns:context="http://www.springframework.org/schema/context"
     xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">



     <resources mapping="/resources/**" location="/resources/" />


     <annotation-driven >annotation-driven>

     <context:component-scan base-package="com.zhang" />

     <context:property-placeholder location="classpath:config.properties" />

     <beans:bean id="sayHelloService" class="com.zhang.service.demoImpl"/>


 beans:beans>

 

 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="DubboDemo" />


     <dubbo:registry protocol="zookeeper" address="${able_zookeeper}"  />

     <dubbo:monitor protocol="registry"/>


     <dubbo:protocol name="dubbo" port="31581" />



     <dubbo:provider delay="-1" timeout="6000" retries="0"/>
     <dubbo:consumer timeout="6000" retries="0"/>
 beans>

 

 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:service interface="com.zhang.service.demo" ref="sayHelloService"  timeout="3000" protocol="dubbo"/>
 beans>

config.properties

 #able_zookeeper
 able_zookeeper=192.168.50.42:2181

4,java代码 一个接口一个实现类

 package com.zhang.service;

 public interface demo {
     public String sayHello();
 }

 

 package com.zhang.service;

 public class demoImpl implements demo {

     @Override
     public String sayHello() {
         return "hello";
     }

 }

 

 

三 DubboClient工程

 

1，pom.xml和web.xml，config.properties配置文件和DubboServer配置一样

2，增加一个消费者配置文件applicationContext-dubbo-consumer.xml，注：这里需要把服务提供者的jar包打入到客户端，打接口就可以

 <strong>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:reference id="demo" interface="com.zhang.service.demo" check="false" protocol="dubbo"/>
 beans> strong>

 3，使用

 package com.zhang.contr;

 

 

四 dubbo-admin-2.5.4.war 管理控制台

    war包下载地址：http://pan.baidu.com/s/1i4xZamD

      把这个war包放到tomcat的webapps目录下 

      1 修改tomcat的端口号不要和其他服务冲突.

      2 修改 WEB-INF 下的dubbo.properties文件

 

      

 

     3 启动tomcat,访问.
