Maven+SpringMVC+Mybatis整合入门Demo

1 数据库准备

（1）建立一个名为mytest的数据库

（2）创建表

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

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。
