SSM项目之商铺系统-实体类的创建(一)

今天是第一天

我们需要准备所需要操作的实体类，我们来看看我们需要哪些实体类？

o2o就是我们的商铺系统

我们看下我创建的实体类：

区域类：店铺所属的区域详情都在这个类里面：

package storepro.entity;

import java.util.Date;

public class Area {//区域类型，比如那些商铺在哪些区域等
    //使用包装类型是因为基础类型会默认赋值。影响操作
    //ID
    private Integer areaId;
    //名称
    private String areaName;
    //权重
    private Integer priority;
    //创建时间
    private Date createTime;
    //更新时间
    private Date lastEditTime;

    public Integer getAreaId() {
        return areaId;
    }

    public void setAreaId(Integer areaId) {
        this.areaId = areaId;
    }

    public String getAreaName() {
        return areaName;
    }

    public void setAreaName(String areaName) {
        this.areaName = areaName;
    }

    public Integer getPriority() {
        return priority;
    }

    public void setPriority(Integer priority) {
        this.priority = priority;
    }

    public Date getCreateTime() {
        return createTime;
    }

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

    public Date getLastEditTime() {
        return lastEditTime;
    }

    public void setLastEditTime(Date lastEditTime) {
        this.lastEditTime = lastEditTime;
    }
}

t头条类：每次打开商铺，都会有轮播图推荐头条内容。头条的内容就是通过这个类完善

package storepro.entity;

import java.util.Date;

public class HeadLine {//头条类
    private Long lineId;//头条id
    private String lineName;//头条名称
    private String lineLink;//头条链接（点一下链接到哪里）
    private String lineImg;//头条图片
    private Integer priority;//权重（决定先显示那些头条）
    private Integer enableStatus;//头条是否可用0不可用，1可用
    private Date createTime;//创建时间
    private Date lastEditTime;//最后修改时间

    public Long getLineId() {
        return lineId;
    }

    public void setLineId(Long lineId) {
        this.lineId = lineId;
    }

    public String getLineName() {
        return lineName;
    }

    public void setLineName(String lineName) {
        this.lineName = lineName;
    }

    public String getLineLink() {
        return lineLink;
    }

    public void setLineLink(String lineLink) {
        this.lineLink = lineLink;
    }

    public String getLineImg() {
        return lineImg;
    }

    public void setLineImg(String lineImg) {
        this.lineImg = lineImg;
    }

    public Integer getPriority() {
        return priority;
    }

    public void setPriority(Integer priority) {
        this.priority = priority;
    }

    public Integer getEnableStatus() {
        return enableStatus;
    }

    public void setEnableStatus(Integer enableStatus) {
        this.enableStatus = enableStatus;
    }

    public Date getCreateTime() {
        return createTime;
    }

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

    public Date getLastEditTime() {
        return lastEditTime;
    }

    public void setLastEditTime(Date lastEditTime) {
        this.lastEditTime = lastEditTime;
    }
}

因为我们的系统实现了微信登录和本系统账户登录，那么我们需要两个类，一个存储本地信息账号，还有一个存储微信信息账号

本地账号类：完成本地注册的账号信息类

package storepro.entity;

import java.util.Date;

public class LocalAuth {//本地账号类
    //本地账号的id
    private Long localAuthId;
    //用户名
    private String userName;
    //密码
    private String password;
    //创建时间
    private Date createTime;
    //更新时间
    private Date lastEditTime;
    //用户信息
    private PersonInfo personInfo;

    public Long getLocalAuthId() {
        return localAuthId;
    }

    public void setLocalAuthId(Long localAuthId) {
        this.localAuthId = localAuthId;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Date getCreateTime() {
        return createTime;
    }

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

    public Date getLastEditTime() {
        return lastEditTime;
    }

    public void setLastEditTime(Date lastEditTime) {
        this.lastEditTime = lastEditTime;
    }

    public PersonInfo getPersonInfo() {
        return personInfo;
    }

    public void setPersonInfo(PersonInfo personInfo) {
        this.personInfo = personInfo;
    }
}

微信账号类：通过微信账号登录，这个类还要包含和本地账号的关联

package storepro.entity;

import java.util.Date;

public class WechatAuth {//微信账号类
    //微信账号的id
    private Long wechatAuthId;
    //微信账号和项目账号绑定的标识，就是用户的id
    private String openId;
    //创建时间
    private Date createTime;
    //用户信息
    private PersonInfo personInfo;

    public Long getWechatAuthId() {
        return wechatAuthId;
    }

    public void setWechatAuthId(Long wechatAuthId) {
        this.wechatAuthId = wechatAuthId;
    }

    public String getOpenId() {
        return openId;
    }

    public void setOpenId(String openId) {
        this.openId = openId;
    }

    public Date getCreateTime() {
        return createTime;
    }

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

    public PersonInfo getPersonInfo() {
        return personInfo;
    }

    public void setPersonInfo(PersonInfo personInfo) {
        this.personInfo = personInfo;
    }
}

个人信息类：用户信息通过这个类存储。

package storepro.entity;

import java.util.Date;

public class WechatAuth {//微信账号类
    //微信账号的id
    private Long wechatAuthId;
    //微信账号和项目账号绑定的标识
    private String openId;
    //创建时间
    private Date createTime;
    //用户信息
    private PersonInfo personInfo;

    public Long getWechatAuthId() {
        return wechatAuthId;
    }

    public void setWechatAuthId(Long wechatAuthId) {
        this.wechatAuthId = wechatAuthId;
    }

    public String getOpenId() {
        return openId;
    }

    public void setOpenId(String openId) {
        this.openId = openId;
    }

    public Date getCreateTime() {
        return createTime;
    }

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

    public PersonInfo getPersonInfo() {
        return personInfo;
    }

    public void setPersonInfo(PersonInfo personInfo) {
        this.personInfo = personInfo;
    }
}

商品类别类：通过这个类完成对商品进行分类

package storepro.entity;

import java.util.Date;

public class ProductCategory {//商品类别类
    private Long productCategoryId; //商品类别id
    private Long shopId;//商铺id，判断这个商品类别是哪个商铺品下的类别
    private String productCategoryName;//商品类别名称
    private Integer priority;//权重
    private Date createTime;

    public Long getProductCategoryId() {
        return productCategoryId;
    }

    public void setProductCategoryId(Long productCategoryId) {
        this.productCategoryId = productCategoryId;
    }

    public Long getShopId() {
        return shopId;
    }

    public void setShopId(Long shopId) {
        this.shopId = shopId;
    }

    public String getProductCategoryName() {
        return productCategoryName;
    }

    public void setProductCategoryName(String productCategoryName) {
        this.productCategoryName = productCategoryName;
    }

    public Integer getPriority() {
        return priority;
    }

    public void setPriority(Integer priority) {
        this.priority = priority;
    }

    public Date getCreateTime() {
        return createTime;
    }

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

商品图片：商品的图片描述存储在这里。

import java.util.Date;

public class ProductCategory {//商品类别类
    private Long productCategoryId; //商品类别id
    private Long shopId;//商铺id，判断这个商品类别是哪个商品下的类别
    private String productCategoryName;//商品类别名称
    private Integer priority;//权重
    private Date createTime;

    public Long getProductCategoryId() {
        return productCategoryId;
    }

    public void setProductCategoryId(Long productCategoryId) {
        this.productCategoryId = productCategoryId;
    }

    public Long getShopId() {
        return shopId;
    }

    public void setShopId(Long shopId) {
        this.shopId = shopId;
    }

    public String getProductCategoryName() {
        return productCategoryName;
    }

    public void setProductCategoryName(String productCategoryName) {
        this.productCategoryName = productCategoryName;
    }

    public Integer getPriority() {
        return priority;

    }

    public void setPriority(Integer priority) {
        this.priority = priority;
    }

    public Date getCreateTime() {
        return createTime;
    }

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

    public Date getLastEditTime() {
        return lastEditTime;
    }

    public void setLastEditTime(Date lastEditTime) {
        this.lastEditTime = lastEditTime;
    }

    public ShopCategory getParent() {

    }

    public void setShopCategory(ShopCategory shopCategory) {
        this.shopCategory = shopCategory;
    }
}

我们来看下他们是通过什么联系起来里的。

微信账号和本地账号通过用户id联系在一起。我们在sql表中也设了外键约束，如果两个账号指向同一个信息则证明是同一个账号，而mysql中不能传入对象，我们在数据库中通过两表的用户id字段来判断是否为同一个账户

店铺信息和这些信息关联起来：

店铺类别：通过店铺信息类的private ShopCategory shopCategory的字段来链接

区域信息：private Area are通过店铺信息类中区域字段来辨别店铺的区域信息。

商品信息：通过商品信息类中的private Shop shop;中的字段来确定是哪个店铺的

商品类别：通过商品类别类中的private Long shopId;字段来确定商品类别是哪个商铺的

商品信息的相关联。

商品类别：通过商品信息类中的private ProductCategory productCategory;来确定商品的类别

详情图片：通过商品图片类中的private Long productId;来确定图片是哪个商品的图片
