首先看项目整体目录

一个个来：

首先建表：简单的一个表，用鱼测试跟数据库链接使用的

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for account
-- ----------------------------‘
create database ssm;
DROP TABLE IF EXISTS `account`;
CREATE TABLE `account` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(20) DEFAULT NULL,
`money` double DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of account
-- ----------------------------
INSERT INTO `account` VALUES ('1', '张三', '100');
