maven+dubbo+SpringMVC 项目搭建

通 maven 创建项目

创建一个父工程 mylongbang--pom : 管理所有子工程.

2.创建子工程分为俩种,一种是 jar 包工程和另一种 war 包工程;区别在于, jar 包工程是依赖于开发,而 war 包工程作将来部署的工程.

mylongbang-interface---jar ; mylongbang-dao ---jar ; mylongbang-common---jar

app ---war ; longwatch5s ---war ; lbvalidate --- war ; weichat ---war ; operate ---war

3.添加依赖比如 : longwatch5s 依赖 mylongbang-interface---jar ; mylongbang-dao ---jar ; mylongbang-common---jar

4. mylongbang父工程pom.xml文件里添加dubbo 的 jar包坐标:

		<!-- dubbo -->
		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>dubbo</artifactId>
			<version>2.5.3</version>
			<exclusions>
				<exclusion>
					<groupId>org.springframework</groupId>
					<artifactId>spring</artifactId>
				</exclusion>
				<exclusion>
					<artifactId>netty</artifactId>
					<groupId>org.jboss.netty</groupId>
				</exclusion>
			</exclusions>
		</dependency>
		<dependency>
			<groupId>org.apache.zookeeper</groupId>
			<artifactId>zookeeper</artifactId>
			<version>3.4.6</version>
		</dependency>
		<dependency>
			<groupId>com.github.sgroschupf</groupId>
			<artifactId>zkclient</artifactId>
			<version>0.1</version>
		</dependency>

需要注意的是,javassist 这个包 3.18.1-GA 有问题,需要重新引入:

        <dependency>
            <groupId>org.javassist</groupId>
            <artifactId>javassist</artifactId>
            <version>3.18.0-GA</version>
        </dependency>

View Code

包坐标加完以后,凡是war 项目报红,不要担心,做如下操作就解决

点击 Generate Deployment Descriptor Stub

然后点击父工程 --> run --> maven install 这样,你的工程就可以在运行容器里 run 调试了!

5.配置 dubbo 注册服务和消费服务的 xml 文件

注册服务

<?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服务提供方配置 -->
    <!-- 配置应用的名称：用于监控 -->
    <dubbo:application name="test"></dubbo:application>
    <!-- 配置注册中心 -->
    <dubbo:registry protocol="zookeeper" address="192.168.191.3:2181"/>
    <!-- 配置dubbo直连 -->
<!--     <dubbo:registry address="N/A"></dubbo:registry>
    <dubbo:protocol name="dubbo" port ="20880"></dubbo:protocol> -->
    <dubbo:service ref="dabboTestService" interface="com.lb.longwatch5s.services.DabboTestService"></dubbo:service>

</beans>

注册服务

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:task="http://www.springframework.org/schema/task" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
    xsi:schemaLocation="http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
        http://www.springframework.org/schema/task
           http://www.springframework.org/schema/task/spring-task-4.0.xsd
        http://code.alibabatech.com/schema/dubbo        
        http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

    <!-- 配置应用的名称：用于监控 -->
    <dubbo:application name="lbvalidate" />

    <!-- 配置注册中心 -->
    <dubbo:registry protocol="zookeeper" address="192.168.191.3:2181" />
    <!-- 配置dubbo直连 -->
    <!-- <dubbo:registry address="N/A"/> <dubbo:reference id="dabboTestService" 
        interface="com.lb.longwatch5s.services.DabboTestService" url="dubbo://127.0.0.1:20880" 
        /> -->

    <!-- 引用服务 -->
    <dubbo:reference id="dabboTestService"
        interface="com.lb.longwatch5s.services.DabboTestService"  />
    <!-- 全局连接超时时间 单位：毫秒 -->
    <dubbo:consumer timeout="60000000" />

</beans>

消费服务

简单的 dubbo 就这样可以 run 了.

Tomcat 在 run 的时候如有报错,请参考 http://www.cnblogs.com/bjxq-cs88/p/8573451.html 解决!
