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

 

 

1. CREATE TABLE `t_user` (   
2. `USER_ID` int(11) NOT NULL AUTO_INCREMENT,   
3. `USER_NAME` char(30) NOT NULL,   
4. `USER_PASSWORD` char(10) NOT NULL,   
5. PRIMARY KEY (`USER_ID`),   
6. KEY `IDX_NAME` (`USER_NAME`)   
7. )ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8  

（3）插入数据

[plain] view plain copy

 

 

1. INSERT INTO t_user (USER_ID, USER_NAME,USER_PASSWORD) VALUES (1, ‘Zhang San‘, ‘654321‘);  
2. 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。
