9.Spring-Boot之Mybatis-LogBack-Freemarker

包结构如下：

​

初始化SQL

DROP TABLE IF EXISTS `user`;

CREATE TABLE `user` (

`id` int(11) NOT NULL AUTO_INCREMENT,

`name` varchar(50) DEFAULT NULL,

`password` varchar(32) DEFAULT NULL,

`age` int(11) DEFAULT NULL,

`phone` varchar(32) DEFAULT NULL,

PRIMARY KEY (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8;



-- ----------------------------

-- Records of user

-- ----------------------------

INSERT INTO `user` VALUES ('1', '张三', '123456', '23', '15094037891');

INSERT INTO `user` VALUES ('3', '李四', '123456', '24', '1509403791');

INSERT INTO `user` VALUES ('5', '赵六', '12345', '34', '15094037891');

INSERT INTO `user` VALUES ('8', '2323', '123456', '445', '44');
