单表CRUD

SQL:

CREATE TABLE `t_user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(50) DEFAULT NULL,
  `sex` varchar(1) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8;

 

目录结构:

url=jdbc:mysql://localhost:3306/web
driver=com.mysql.jdbc.Driver
userName=root
password=risetek
