SpringMVC入门学习案例笔记

一、数据库环境用mysql，数据库建表语句如下：

/*
SQLyog v10.2
MySQL - 5.1.72-community : Database - mybatis
*********************************************************************
*/

/*!40101 SET NAMES utf8 */;

/*!40101 SET SQL_MODE=‘‘*/;

/*!40014 SET @[email protected]@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @[email protected]@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET @[email protected]@SQL_MODE, SQL_MODE=‘NO_AUTO_VALUE_ON_ZERO‘ */;
/*!40111 SET @[email protected]@SQL_NOTES, SQL_NOTES=0 */;
/*Table structure for table `items` */

DROP DATABASE IF EXISTS `mybatis`;
CREATE DATABASE `mybatis` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

USE `mybatis`;

SET FOREIGN_KEY_CHECKS=0;

DROP TABLE IF EXISTS `items`;
CREATE TABLE `items` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(32) NOT NULL COMMENT ‘商品名称‘,
  `price` float(10,1) NOT NULL COMMENT ‘商品定价‘,
  `detail` text COMMENT ‘商品描述‘,
  `pic` varchar(64) DEFAULT NULL COMMENT ‘商品图片‘,
  `createtime` datetime NOT NULL COMMENT ‘生产日期‘,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;
insert  into `items`(`id`,`name`,`price`,`detail`,`pic`,`createtime`) values (1,‘台式机‘,3000.0,‘该电脑质量非常好！！！！‘,NULL,‘2015-02-03 13:22:53‘),(2,‘笔记本‘,6000.0,‘笔记本性能好，质量好！！！！！‘,NULL,‘2015-02-09 13:22:57‘),(3,‘背包‘,200.0,‘名牌背包，容量大质量好！！！！‘,NULL,‘2015-02-06 13:23:02‘);

/*Table structure for table `orderdetail` */

DROP TABLE IF EXISTS `orderdetail`;
CREATE TABLE `orderdetail` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `orders_id` int(11) NOT NULL COMMENT ‘订单id‘,
  `items_id` int(11) NOT NULL COMMENT ‘商品id‘,
  `items_num` int(11) DEFAULT NULL COMMENT ‘商品购买数量‘,

  KEY `FK_orderdetail_2` (`items_id`),
  CONSTRAINT `FK_orderdetail_1` FOREIGN KEY (`orders_id`) REFERENCES `orders` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION,
  CONSTRAINT `FK_orderdetail_2` FOREIGN KEY (`items_id`) REFERENCES `items` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;
insert  into `orderdetail`(`id`,`orders_id`,`items_id`,`items_num`) values (1,3,1,1),(2,3,2,3),(3,4,3,4),(4,4,2,3);

/*Table structure for table `orders` */

DROP TABLE IF EXISTS `orders`;
CREATE TABLE `orders` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `user_id` int(11) NOT NULL COMMENT ‘下单用户id‘,
  `number` varchar(32) NOT NULL COMMENT ‘订单号‘,

  KEY `FK_orders_1` (`user_id`),
  CONSTRAINT `FK_orders_id` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;
insert  into `orders`(`id`,`user_id`,`number`,`createtime`,`note`) values (3,1,‘1000010‘,‘2015-02-04 13:22:35‘,NULL),(4,1,‘1000011‘,‘2015-02-03 13:22:41‘,NULL),(5,10,‘1000012‘,‘2015-02-12 16:13:23‘,NULL);
/*Table structure for table `user` */

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(32) NOT NULL COMMENT ‘用户名称‘,
  `birthday` date DEFAULT NULL COMMENT ‘生日‘,
  `sex` char(1) DEFAULT NULL COMMENT ‘性别‘,
  `address` varchar(256) DEFAULT NULL COMMENT ‘地址‘,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=27 DEFAULT CHARSET=utf8;
insert  into `user`(`id`,`username`,`birthday`,`sex`,`address`) values (1,‘王五‘,NULL,‘2‘,NULL),(10,‘张三‘,‘2014-07-10‘,‘1‘,‘北京市‘),(16,‘张小明‘,NULL,‘1‘,‘河南郑州‘),(22,‘陈小明‘,NULL,‘1‘,‘河南郑州‘),(24,‘张三丰‘,NULL,‘1‘,‘河南郑州‘),(25,‘陈小明‘,NULL,‘1‘,‘河南郑州‘),(26,‘王五‘,NULL,NULL,NULL);
/*!40101 SET [email protected]_SQL_MODE */;
/*!40014 SET [email protected]_FOREIGN_KEY_CHECKS */;
/*!40014 SET [email protected]_UNIQUE_CHECKS */;
/*!40111 SET [email protected]_SQL_NOTES */;

建表成功之后数据库如图所示：

java的环境是jdk1.7，eclipse使用mars2，spring使用3.2的版本。spring3.2所需要的jar包如图所示：

至此，所需要的软件和环境都准备完毕。
