spring boot商品添加模块多表插入-全栈篇-前后端不分离

spring boot商品添加模块多表插入

废话不说直接开始

1.1数据库表关系

1.1.2主表 tb_item

后端

1.1.3关联表 td_item_lei

1.1.4tb_item的id对应了td_item_lei的item_id

2.开发软件及技术

Mysql
eclipse
mybatis-plus

pox.xml

没有把整个pox复进来,看自己需要什么依赖往上加就行了

	<properties>
		<java.version>1.8</java.version>
		<maven-jar-plugin.version>3.0.0</maven-jar-plugin.version>
		<!-- 跳过测试类打包 -->
		<skipTests>true</skipTests>
	</properties>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-jdbc</artifactId>
		</dependency>
		<!-- mysql -->
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
		<scope>runtime</scope>
		</dependency>
		<!--spring-test测试=-->
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-test</artifactId>
		</dependency>
		<!-- 基于mybatis框架实现的一个分页插件 -->
		<dependency>
			<groupId>com.github.pagehelper</groupId>
			<artifactId>pagehelper-spring-boot-starter</artifactId>
			<version>1.2.13</version>
		</dependency>
		<!-- mysql-plus -->
		<dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.3.1</version>
        </dependency>
	    <!-- 添加AOP的依赖 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-aop</artifactId>
		</dependency>

3.定义实体类POJO

3.1ItemCat 商品基本信息

package com.cy.pj.common.pojo;

import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import lombok.Data;
import lombok.experimental.Accessors;

@JsonIgnoreProperties(ignoreUnknown = true)
@TableName("tb_item")
@Data
@Accessors(chain = true)
public class Item {
    @TableId(type = IdType.AUTO)
    //id
    private Long id;
    //卖点
    private String title;
    //标题
    private String sellpointa;
    //标题
    private String sellpointb;
    //标题
    private String sellpointc;
    //标题
    private String sellpointd;
    //标题
    private String sellpointe;
    //价格
    private Long price;
    //数量
    private String num;
    //图片
    private String image;
    //分类id
    private Long cid;
    //1正常，2下架
    private Integer status;		
     //下面加入get set方法
}	

3.2ItemDesc商品参数信息(可以加get set方法，太长了没有复出来)

package com.cy.pj.common.pojo;

import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;
import lombok.experimental.Accessors;

@TableName("td_item_lei")
@Data
@Accessors(chain = true)
public class ItemDesc {

    @TableId
    private Long itemId;
    //型号
    private String model;
    //品牌
    private String brand;
    //公价
    private Long official;
    //表径
    private String size;
    //表壳
    private String watchcase;
    //表带
    private String watch;
    //功能
    private String pass;
    //附属品
    private String accessory;
    //款式
    private String style;
    //机芯
    private String movment;
    //颜色
    private String colour;
    
    }

4.定义mapper(其实是继承mybatis-plus方法)

4.1ItemitemMapper (继承mybatis通用方法)

package com.cy.pj.sys.dao;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.cy.pj.common.pojo.Item;

public interface ItemitemMapper extends BaseMapper<Item>{

}

4.2ItemitemDescMapper

package com.cy.pj.sys.dao;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.cy.pj.common.pojo.ItemDesc;

public interface ItemitemDescMapper extends BaseMapper<ItemDesc> {

}

5.service

package com.cy.pj.sys.service;

import com.cy.pj.common.pojo.Item;
import com.cy.pj.common.pojo.ItemDesc;

public interface ItemitemService {
	
	 /**
     * 商品添加
     * @param item
     * @param itemDesc
     */
    void saveItem(Item item, ItemDesc itemDesc);
    
}

6.serviceImpl

package com.cy.pj.sys.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.cy.pj.common.pojo.Item;
import com.cy.pj.common.pojo.ItemDesc;
import com.cy.pj.sys.dao.ItemitemDescMapper;
import com.cy.pj.sys.dao.ItemitemMapper;
import com.cy.pj.sys.service.ItemitemService;

@Service
public class ItemitemServiceImpl implements ItemitemService{
	
    @Autowired(required = false)
   // @Autowired
    private ItemitemMapper itemMapper;

    @Autowired
    private ItemitemDescMapper itemDescMapper;

    @Override
    @Transactional
    public void saveItem(Item item, ItemDesc itemDesc) {
        item.setStatus(1);
        itemMapper.insert(item);
        itemDesc.setItemId(item.getId());
        itemDescMapper.insert(itemDesc);

    }

   
}

前端

用的是HTML 最终效果如下

HTML解释起来比较复杂，直接复制整个页面出来，每一行代码起什么作用都有注解

<!DOCTYPE html>
<html lang="en">

    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
