Maven+SpringMVC+Mybatis 整合使用教程

转载自：http://blog.csdn.net/haishu_zheng/article/details/51534689

1 数据库准备

（1）建立一个名为mytest的数据库

（2）创建表

[plain] view
plain copy

CREATE TABLE `t_user` (

`USER_ID` int(11) NOT NULL AUTO_INCREMENT,

`USER_NAME` char(30) NOT NULL,

`USER_PASSWORD` char(10) NOT NULL,

PRIMARY KEY (`USER_ID`),

KEY `IDX_NAME` (`USER_NAME`)

)ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8

（3）插入数据

[plain] view
plain copy

INSERT INTO t_user (USER_ID, USER_NAME,USER_PASSWORD) VALUES (1, 'Zhang San', '654321');

INSERT INTO t_user (USER_ID, USER_NAME,USER_PASSWORD) VALUES (2, 'Li Si', '123456');

2 参考http://blog.csdn.net/haishu_zheng/article/details/51490299，用第二种方法创建一个名为maven_springmvc_mybatis_demo的工程。

3 文件目录结构如下图所示
