从零开发校园商铺平台（SSM到SpringBoot）一.开发准备，实体类设计与表创建

2023-10-31

依山傍水房树间，行也安然，住也安然；
一条耕牛半顷田，收也凭天，荒也凭天；
雨过天晴驾小船，鱼在一边，酒在一边；
夜晚妻子话灯前，今也谈谈，古也谈谈；
日上三竿犹在眠，不是神仙，胜似神仙！

一.开发准备

创建maven项目

新增pom.xml文件代码

<build>
        <finalName>o2o</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>

我们想要修改Dynamic Web Module成3.1但是eclipse不让我们改，那我们先改回。2.3版本

这里写图片描述

通过终端去访问项目

这里写图片描述

这里写图片描述

通过命令 vi org.eclipse.wst.common.project.facet.core.xml 打开进行配置修改为<installed facet="jst.web" version="3.1"/>

回到eclipse，刷新项目，我们就可以看到我们想要修改的Dynamic Web Module版本为3.1。

然后修改web.xml为

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                      http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    version="3.1" metadata-complete="true">
    <display-name>Archetype Created Web Application</display-name>
</web-app>

运行项目，没有报错，正常启动。

创建com.imooc.o2o.entity Area.java类

package com.imooc.o2o.entity;

import java.util.Date;

public class Area {

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

}

创建名o2o的数据库

创建表

create table tb_area(
    area_id int(2) NOT NULL AUTO_INCREMENT,
    area_name varchar(200) NOT NULL,

创建对应数据表

CREATE TABLE tb_product(
    product_id int(100) NOT NULL AUTO_INCREMENT,
    product_name varchar(100) NOT NULL,
    product_desc varchar(2000) DEFAULT NULL,

    enable_status int(2) NOT NULL DEFAULT 0,
    product_category_id int(11) DEFAULT NULL,
    shop_id int(20) NOT NULL DEFAULT 0,
    PRIMARY KEY(product_id),
    CONSTRAINT fk_product_procate FOREIGN KEY(product_category_id) REFERENCES tb_product_category(product_category_id),
    CONSTRAINT fk_product_shop FOREIGN KEY(shop_id) REFERENCES tb_shop(shop_id)
 )ENGINE =InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

创建商品图片实体类与数据表

创建实体类ProductImg.java

package com.imooc.o2o.entity;

import java.util.Date;

public class ProductImg {

    private Long productImgId;
    private String imgAddr;
    private String imgDesc;
    private Integer priority;
    private Date createTime;
    private Long productId;

    public Long getProductImgId() {
        return productImgId;
    }
    public void setProductImgId(Long productImgId) {
        this.productImgId = productImgId;
    }
    public String getImgAddr() {
        return imgAddr;
    }
    public void setImgAddr(String imgAddr) {
        this.imgAddr = imgAddr;
    }
    public String getImgDesc() {
        return imgDesc;
    }
    public void setImgDesc(String imgDesc) {
        this.imgDesc = imgDesc;
    }
    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 Long getProductId() {
        return productId;
    }
    public void setProductId(Long productId) {
        this.productId = productId;
    }

}

创建对应数据表(先创建tb_product)

CREATE TABLE tb_product_img(
  product_img_id int(20) NOT NULL AUTO_INCREMENT,
  img_addr varchar(2000) NOT NULL,
  img_desc varchar(2000) DEFAULT NULL,
  priority int(2) DEFAULT 0,
  create_time  datetime DEFAULT NULL,
  product_id int(20) DEFAULT NULL,
  PRIMARY KEY(product_img_id),
  CONSTRAINT fk_proimg_product FOREIGN KEY(product_id) REFERENCES tb_product(product_id)
)ENGINE =InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
