SSM基础框架一

1.SSM基础框架

1. 创建user数据表
create table t_user(
id int(11) NOT NULL AUTO_INCREMENT,
userName varchar(20) DEFAULT NULL,
password varchar(20) DEFAULT NULL,
PRIMARY KEY(id)
)ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8;

insert into t_user values(1, 'andrew', '123456');

2. 新建MyBatisPro05项目

3. 导入jar包
