用spring+springMVC+mybatis实现模拟秒杀项目（一）

声明：本项目代码参考自慕课网视频

这是在IDEA环境下创建的maven项目，创建过程就不多说了。

首先配置pom.xml,配置如下：

3.实体类层开发：

秒杀商品实体类

SecKill：

package com.leoms.entity;

import java.util.Date;

/**
* Created by LeoMs on 2017/4/23 0023.
* 秒杀商品列表seckill对应实体类
*/
public class Seckill {

//秒杀商品ID号，主键，自增
private long seckillId;

//秒杀商品名称
private String name;

//秒杀商品剩余量
private int number;

//秒杀商品开始秒杀日期时间
private Date startTime;

//秒杀商品结束秒杀日期时间
private Date endTime;

//秒杀商品创建时间
private Date createTime;

public long getSeckillId() {
return seckillId;
}

public void setSeckillId(long seckillId) {
this.seckillId = seckillId;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getNumber() {
return number;
}

public void setNumber(int number) {
this.number = number;
}

public Date getStartTime() {
return startTime;
}

public void setStartTime(Date startTime) {
this.startTime = startTime;
}

public Date getEndTime() {
return endTime;
}

public void setEndTime(Date endTime) {
this.endTime = endTime;
}

public Date getCreateTime() {
return createTime;
}

public void setCreateTime(Date createTime) {
this.createTime = createTime;
}

@Override
public String toString() {
return "Seckill{" +
"seckillId=" + seckillId +
", name='" + name + '\'' +
", number=" + number +
", startTime=" + startTime +
", endTime=" + endTime +
", createTime=" + createTime +
'}';
}
}

秒杀成功明细表实体类

SuccessSeckilled：

package com.leoms.entity;

import java.util.Date;

/**
* Created by LeoMs on 2017/4/23 0023.
* 成功秒杀商品列表success_killed对应实体类
*/
public class SuccessKilled {

//秒杀商品ID号
private long seckillId;

//用户手机号码
private String userPhone;

//存放秒杀状态
private short state;

//创建时间
private Date createTime;

//多对一，因为一件商品在库存中有很多数量，对应的购买明细也很多
private Seckill seckill;

public long getSeckillId() {
return seckillId;
}

public void setSeckillId(long seckillId) {
this.seckillId = seckillId;
}

public String getUserPhone() {
return userPhone;
}

public void setUserPhone(String userPhone) {
this.userPhone = userPhone;
}

public short getState() {
return state;
}

public void setState(short state) {
this.state = state;
}

public Date getCreateTime() {
return createTime;
}

public void setCreateTime(Date createTime) {
this.createTime = createTime;
}

public Seckill getSeckill() {
return seckill;
}

public void setSeckill(Seckill seckill) {
this.seckill = seckill;
}

@Override
public String toString() {
return "SuccessKilled{" +
"seckillId=" + seckillId +
", userPhone='" + userPhone + '\'' +
", state=" + state +
", createTime=" + createTime +
", seckill=" + seckill +
'}';
}
}
