搭建 Dubbo+Zookeeper+SpringMVC项目

今天主要说的是Dubbo+Zookeeper分布式服务的搭建，前面我们搭建过web层也就是http层的负载均衡，由nginx去操作的，所以今天不做整合，只对分布式项目进行搭建

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

api接口的实现类

对于服务方发布的main方法，Provider类

[java]  view plain  copy

1. package com.dubbo.provider;  
2.   
3. import org.apache.log4j.PropertyConfigurator;  
4. import org.springframework.context.support.ClassPathXmlApplicationContext;  
5.   
6. public class Provider {  
7.   
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）

这个时候我们进入dubbo-admin里面去查看一下消费方

然后这里大家可以用url去测试，也可以用postman去测试

点击Send发送请求后我们可以看到控制台的输出

五、至此我们的dubbo+zookeeper+springmvc的分布式项目已经搭建完成，小伙伴儿们去试试吧~~~
