我是靠谱客的博主 不安大叔，最近开发中收集的这篇文章主要介绍一个简单的SSM+dubbo分布式应用Demo1. 概述2. 环境准备3. dubboDemo_web项目实现4. dubboDemo_service项目实现，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1. 概述

        本文指导在eclipse下快速搭建一个SSM+dubbo分布式应用Demo，作为后续分布式技术学习基础。

        主要两个工程，web层为dubbo_web，control和dao层为dubbo_service

        dubbo_web工程github地址： https://github.com/WeedOutWorld/dubboDemo_web/tree/dev

        dubbo_service工程github地址： https://github.com/WeedOutWorld/dubboDemo_service/tree/dev



2. 环境准备

        eclispe、mysql、maven、jdk1.7

        eclipse maven插件安装:  https://www.cnblogs.com/cynchanpin/p/6848452.html


3. dubboDemo_web项目实现

        3.1 从git上导入项目dubboDemo_web至eclipse

            


        3.2 配置pom.xml （采用jetty-maven插件作为服务器）

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

  <artifactId>dubboDemo_web</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>dubboDemo_web Maven Webapp</name>
  <url>http://maven.apache.org</url>

        3.3 配置web.xml

            配置监听以及mvc的servlet

<?xml version="1.0" encoding="UTF-8"?>

<web-app>
  <display-name>Archetype Created Web Application</display-name>
  <welcome-file-list>
  	<welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
	<!-- 监听 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-all.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	<!--配置DispatcherServlet -->
	<servlet>
		<servlet-name>spring-dispatcher</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring/spring-web.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>spring-dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

	
  
</web-app>


        3.4 配置src/main/resources

            在spring-all.xml中配置所有需要经由spring加载的配置文件（现在各类组件基本上都经由spring加载）

<?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:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="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
		http://www.springframework.org/schema/mvc 
		http://www.springframework.org/schema/mvc/spring-mvc.xsd">

	
    <!--作为消费者导入远程接口-->
    <import resource="classpath:dubbo/dubbo-consumer.xml"/>
    <!--springmvc-->
    <import resource="classpath:spring/spring-web.xml"/>
</beans>

    dubbo-consumer.xml文件，默认以zookeeper为注册中心，如果采用直连，将dubbo:registry与dubbo:reference注释进行替换

<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-2.5.xsd
	   http://code.alibabatech.com/schema/dubbo
	   http://code.alibabatech.com/schema/dubbo/dubbo.xsd">


	<!-- 消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 -->
	<dubbo:application name="dubboDemo_web"  owner="ych"/>

	<!-- 使用zookeeper注册中心获取服务地址 -->
	<dubbo:registry protocol="zookeeper" address="zookeeper://127.0.0.1:2181" />
	<!-- <dubbo:registry address="N/A" /> -->
	
	<!-- 用户服务接口 -->
	<dubbo:reference interface="org.ych.dubboDemo.core.BooksService" id="booksService"/>
	<!-- 
	<dubbo:reference interface="org.ych.dubboDemo.core.BooksService" id="booksService" url="dubbo://127.0.0.1:20880"/>
	 -->
</beans>

spring-web.xml文件，mvc配置

<?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:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="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
		http://www.springframework.org/schema/mvc 
		http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <mvc:annotation-driven />

    <mvc:default-servlet-handler/>

	<!-- 扫描相关注解包 -->
    <context:component-scan base-package="org.ych.dubboDemo"/>
    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>


</beans>

        3.5 配置src/main/java

            dubbo服务接口BooksService.java，注入任意需要的类中使用
，        


4. dubboDemo_service项目实现

        4.1 从git上导入项目dubboDemo_web至eclipse

            

        4.2 配置pom.xml

            同上

        4.3 配置web.xml

            同上，只需要配置监听即可

        4.4 配置src/main/resources

<?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:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="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
		http://www.springframework.org/schema/mvc 
		http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <import resource="classpath:dubbo/dubbo-provider.xml"/>
    
    <import resource="classpath:spring/spring-dao.xml"/>
	
	<!-- 扫描beans包 -->
    <context:component-scan base-package="org.ych.dubboDemo"/>
    
</beans>

            dubbo-provider.xml文件，默认以zookeeper为配置中心，如果希望直连，取消注释覆盖dubbo:registry

<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-2.5.xsd
	   http://code.alibabatech.com/schema/dubbo
	   http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

	<!-- 提供方应用信息，用于计算依赖关系 -->
	<dubbo:application name="dubboDemo_service" owner="ych"/>

	<!-- 使用zookeeper注册中心暴露服务地址 -->
	<dubbo:registry protocol="zookeeper" address="zookeeper://127.0.0.1:2181" />
	<!-- <dubbo:registry  address="N/A" /> -->

	<!-- 用dubbo协议在20880端口暴露服务 -->
	<dubbo:protocol name="dubbo" port="20880" />

	<!-- 当ProtocolConfig和ServiceConfig某属性没有配置时,采用此缺省值 -->
	<dubbo:provider timeout="10000" threadpool="fixed" threads="100" accepts="1000" />

	<!-- 暴露服务接口 一个服务可以用多个协议暴露，一个服务也可以注册到多个注册中心-->
	<dubbo:service interface="org.ych.dubboDemo.core.BooksService" ref="booksService" />

    <!--具体实现该接口的 bean-->
    <!-- <bean id="booksService" class="org.ych.techDemo_service.service.impl.BooksServiceImpl"/>
 -->
</beans>

        4.5 配置src/main/java

           编写dubbo服务接口实现类BooksServiceImpl.java


注意：如果未使用数据库，注释掉如下两个地方即可
