maven+spring+dubbo搭建web项目

最近在学习分布式的一些技术知识，搭了个demo项目，边学边写边补充。

由于是maven项目，直接上pom文件的依赖:

<dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>4.3.13.RELEASE</version>
    </dependency>

    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>javax.servlet-api</artifactId>
      <version>3.1.0</version>
      <scope>provided</scope>
    </dependency>
  <!-- 添加Spring context依赖 -->
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>org.springframework.context</artifactId>
    <version>3.1.2.RELEASE</version>
  </dependency>
  <!-- 引入Dubbo依赖 -->
  <dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>dubbo</artifactId>
    <version>2.5.3</version>
  </dependency>
  <!-- zookeeper依赖 -->
  <dependency>
    <groupId>org.apache.zookeeper</groupId>
    <artifactId>zookeeper</artifactId>
    <version>3.4.6</version>
  </dependency>
  <!-- zookeeper客户端 zkclient -->
  <dependency>
    <groupId>com.github.sgroschupf</groupId>
    <artifactId>zkclient</artifactId>
    <version>0.1</version>
  </dependency>
  </dependencies>

项目结构：

zookeeper我已经部署好了，服务提供者和消费者记得分别引出接口的依赖，接下来就是写spring配置文件了。

serviceImpl的spring配置文件：

<?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:context="http://www.springframework.org/schema/context"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
    xmlns:jee="http://www.springframework.org/schema/jee"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:util="http://www.springframework.org/schema/util"
    xmlns:jpa="http://www.springframework.org/schema/data/jpa"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
        http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd
        http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd
        http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

   <context:component-scan base-package="xxx"/>
    <!-- 配置别名，目的是在后台可以看到这个服务的别名,这个参数可以随便写，见名知意-->
   <dubbo:application name="test1"></dubbo:application>
   <!-- 配置注册中心
   address 注册中心的地址
   protocol 注册中心的协议格式-->
   <dubbo:registry address="xxx:2181" protocol="zookeeper"></dubbo:registry>
   <!--告诉注册中心我是谁
    interface 代表类型
    ref 代表具体发布哪个服务
    timeout 连接超时时间-->
   <dubbo:service interface="xxx.testdubbo.TestService" ref="testService" timeout="60000"></dubbo:service>
  <!--配置端口，端口可以随便写，一个dubbo独占一个端口 -->
   <dubbo:protocol name="dubbo" port="12345"></dubbo:protocol>
</beans>

webdemo的配置文件：

<?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:context="http://www.springframework.org/schema/context"
    xmlns:jdbc="http://www.springframework.org/schema/jdbc"
    xmlns:jee="http://www.springframework.org/schema/jee"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:util="http://www.springframework.org/schema/util"
    xmlns:jpa="http://www.springframework.org/schema/data/jpa"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
        http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd
        http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
        http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
    <context:component-scan base-package="xxx"></context:component-scan>
    <!-- 配置我是谁-->
    <dubbo:application name="demo"></dubbo:application>
    <!--配置注册中心-->
    <dubbo:registry address="xxx:2181" protocol="zookeeper"></dubbo:registry>
    <!--告诉他我需要什么-->
    <dubbo:reference interface="xxx.TestService" id="testService"></dubbo:reference>
</beans>

然后分别启动就可以了。
