前言：Dubbo （https://github.com/alibaba/dubbo）是阿里巴巴开源的分布式服务化治理框架（微服务框架），历经阿里巴巴电商平台的大规模复杂业务的高并发考验，到目前为止Dubbo仍然是开源界中体系最完善的服务化治理框架，因此Dubbo被国内大量的的互联网公司和专统企业使用，国内使用Dubbo的企业有：阿里巴巴、京东、电信运营商等。

京东、当当、去哪儿等企业还组建了自己的中间件团队按自己的业务需求对Dubbo进行框架定制，目前当当网已开源了自己的Dubbo定制版Dubbox ：http://www.oschina.net/p/dubbox

当当对Dubbo的评价：Dubbo是一个被国内很多互联网公司广泛使用的开源分布式服务框架，即使从国际视野来看应该也是一个非常全面的SOA基础框架。作为一个重要的技术研究课题，在当当网我们根据自身的需求，为Dubbo实现了一些新的功能，并将其命名为Dubbox（即Dubbo eXtensions）。

开发环境：这个根据个人的喜欢，没有强制的。喜欢用什么版本就用什么版本。

Window 7 64；Eclipse ；Apache-Maven-3.3.9；Spring ；Mybatis；Springmvc；Dubbo 2.5.3，

开发思路：

  • 一般开发是先设计数据库：那么这里也很简单的创建一个用户表。
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `user_id` varchar(100) NOT NULL COMMENT '用户ID',
  `user_name` varchar(100) DEFAULT NULL COMMENT '用户名称',
  `age` int(11) DEFAULT NULL COMMENT '年龄',
  PRIMARY KEY (`user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='用户表';


INSERT INTO `user` VALUES ('1', 'zhangsan', '18');
INSERT INTO `user` VALUES ('2', 'lisi', '19');
INSERT INTO `user` VALUES ('3', 'wangwu', '20');
INSERT INTO `user` VALUES ('4', 'zhaoliu', '21');

本文采用聚合工程模式：创建父工程和子工程，目录结构如下：

  • 依赖关系说明：
  • 1：ssm-dubbo-parent是pom文件的父工程，父目录工程的主要作用是统一大家所使用的jar包依赖。
  • 2：ssm-dubbbo-common与ssm-dubbbo-controller与ssm-dubbbo-service首先都是依赖于父目录工程。
  • 3：ssm-dubbbo-common是jar包，里面存放interface，bean，dao等公用内容。
  • 4：ssm-dubbbo-controller控制层和ssm-dubbbo-service业务层是war包,也就是各分为一个Tomcat。
  • 5：ssm-dubbbo-service依赖于ssm-dubbbo-common，ssm-dubbbo-controller依赖于ssm-dubbbo-service

父工程目录如下：

父目录管理的pom.xml具体代码如下：

<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/xsd/maven-4.0.0.xsd">

  <groupId>com.demo</groupId>
  <artifactId>ssm-dubbo-parent</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>pom</packaging>
  <description>这是一个ssm与dubbo的整合父目录工程</description>

ssm-dubbo-service项目工程如下：

至此：聚合工程就搭建好了，接下是ssm的相应整合，相信网上已经有很多的分享。理解就比较简单了。

那么主要是配置ssm-dubbo-service与ssm-dubbo-controller.

ssm-dubbo-service下的配置结构目录具体如下：

		<property name="suffix" value=".jsp"/>
	</bean>
	
	<import resource="dubbo-consumer.xml"/>
	
</beans>

springmvc.xml配置代码如下：

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

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n

ssm-dubbo-controller的web.xml配置如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

		 -->
		 <servlet-name>springmvc</servlet-name>
		 <url-pattern>/</url-pattern>
	</servlet-mapping>
</web-app>

到这，相应的配置就完成了，接下来就是简单的编写代码测试：

这里简单的编写公用的的具体结构如下：

控制表现层代码很简单的，如下：

启动项目：先启动ssm-dubbo-service,然后再启动项目ssm-dubbo-controller..浏览器输入：http://localhost:8081/user?userId=2

结果如图

到此，所有的全都弄好了。

哎，累死我了，编码不易，继续加油！！！项目中你可能会遇到一此错误，那么不断的调试一定会成功的！！！这里小编也把项目源码上传了，希望对于你有帮助。

源码已经上传：https://download.csdn.net/download/qq_30764991/10568372

如果对您有帮助 ，请多多支持.多少都是您的心意与支持，一分也是爱，再次感谢！！！
