搭建 Dubbo+Zookeeper+SpringMVC项目

Dubbo+Zookeeper分布式服务的搭建

搭建过程：

一、我们要下载Zookeeper并安装、配置

下载地址：http://apache.fayea.com/zookeeper/ 我下载的是3.5.3-beta 测试版本进行搭建的，大家可以选择稳定版

我们把下载下来的zookeeper进行解压，打开后我们进入到 zookeeper-3.5.3\conf 这个文件夹

打开zoo.cfg，对zookeeper的端口和log、data进行配置

返回，进入bin目录我们启动zkServer.cmd，zookeeper就启动了

二、下载配置dubbo的管理项目

下载地址：https://download.csdn.net/download/qq_27612843/10465247

接下来我们需要准备个tomcat，改好端口，避免冲突，并且把下载的dubbo-admin.war放入到webapps里面

启动后会自动解压，这里要说一下流程，必须得是先启动zookeeper注册中心，然后再启动dubbo-admin服务

还有一个需要注意的地方是在 webapps—>dubbo-admin—>WEB-INF—>dubbo.properties文件中的zookeeper端口必须要和你zookeeper的端口保持一致

启动tomcat之后我们进行访问可以看到会让我们输入用户名和密码，都是root

登录进去之后就是dubbo的管理项目

三、接下来我们来创建我们的dubbo项目，这里我采用maven聚合来进行搭建

dubbo 父节点 Packaging——pom

dubbo-api 接口（也就是我们的service接口） Packaging——jar

dubbo-provider 服务提供方（这里面写service的实现和数据持久）、需要在pom中引入dubbo-api Packaging——war

dubbo-consumer 消费方（可以理解为controller层的调用）、需要在pom中引入dubbo-api Packaging——war

下面搭建流程就是一个maven聚合，我把各个程序里面所需要的配置贴出来

1、dubbo-api什么都不需要配置，只用写出我们一个接口即可

2、dubbo-provider的pom.xml的配置，dubbo自带的spring版本较低对其进行替换，大家自行把groupId和artifactId改名

1. <?xml version="1.0"?>

7. <!-- 提供方应用信息，用于计算依赖关系 -->
8. <dubbo:application name="provider" />
10. <!-- 使用zookeeper广播注册中心暴露服务地址 -->
11. <dubbo:registry address="zookeeper://127.0.0.1:2181"/>
13. <!-- 用dubbo协议在20880端口暴露服务 -->

19. <!-- 声明需要暴露的服务接口 -->
20. <dubbo:service interface="com.dubbo.api.TestService" ref="testService" />
22. </beans>

api接口的实现类

对于服务方发布的main方法，Provider类

1. package com.dubbo.provider;
3. import org.apache.log4j.PropertyConfigurator;
4. import org.springframework.context.support.ClassPathXmlApplicationContext;
6. public class Provider {
8. static{
9. PropertyConfigurator.configure("src/main/resources/log4.properties");
10. }
11. public static void main(String args[]) throws Exception {
12. ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath*:/*.xml");
13. context.start();
14. System.in.read();
15. }
16. }

我们用main方法启动后进入dubbo-admin里面去查看一下，会发现我们的服务已经发布了

3、接下来编写消费者项目代码及配置 dubbo-consumer

首先是pom.xml的配置

四、启动我们的消费方，dubbo-consumer（这里要注意一下，在拿个tomcat出来，不要和dubbo-admin用同一个）
