一、案例介绍
1.1 需求
完成对用户表的CRUD操作。
1.2 项目架构方式
SOA面向服务架构
1.3 技术选型
maven，Spring，SpringMVC,Mybatis,Dubbo,Zookeeper,MySql
二、创建表
CREATE TABLE `users` (
`userid` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(30) DEFAULT NULL,
`userage` int(11) DEFAULT NULL,
PRIMARY KEY (`userid`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;
三、项目设计
dubbo-parent (POM)
|--dubbo-pojo (jar)
|--dubbo-mapper (jar)
|--dubbo-user-provider (POM)
|--dubbo-user-provider-interface (jar)
|--dubbo-user-provider-service (jar)
|--dubbo-user-consumer (pom)
|--dubbo-user-consumer-portal-service (jar)
|--dubbo-user-consumer-protal (war)
四、创建项目
1.创建dubbo-parent
1.1 创建项目
1.2 修改POM文件
