菜品新增

分析：

后台系统中可以管理菜品信息，通过 新增功能来添加一个新的菜品，在添加菜品时需要选择当前菜品所属的菜品分类，并且需要上传菜品图片，在移动端会按照菜品分类来展示对应的菜品信息 。

 

 新增菜品，其实就是将新增页面录入的菜品信息插入到dish表，如果添加了口味做法，还需要向dish_flavor表插入数据。所以在新增菜品时，涉及到两个表：

 菜品代码准备：

1.entity

package com.itheima.reggie.entity;import com.baomidou.mybatisplus.annotation.FieldFill;

import com.baomidou.mybatisplus.annotation.TableId;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import lombok.EqualsAndHashCode;import java.io.Serializable;
import java.math.BigDecimal;
import java.time.LocalDateTime;/*** 菜品*/
@Data
@EqualsAndHashCode(callSuper = false)
public class Dish implements Serializable {private static final long serialVersionUID = 1L;/*** 菜品的id*/private Long id;/*** 菜品名称*/@ApiModelProperty("菜品名称")private String name;/*** 菜品分类id 就是套餐分类/菜品分类的id*/@ApiModelProperty("菜品分类id")private Long categoryId;/*** 菜品价格*/@ApiModelProperty("菜品价格")private BigDecimal price;/*** 商品码*/@ApiModelProperty("商品码")private String code;/*** 图片*/@ApiModelProperty("图片")private String image;/*** 描述信息*/@ApiModelProperty("描述信息")private String description;/*** 菜品状态：0 停售 1 起售*/@ApiModelProperty("菜品状态：0 停售 1 起售")private Integer status;/*** 顺序*/@ApiModelProperty("顺序")private Integer sort;/*** 创建时间*/@ApiModelProperty("创建时间")@TableField(fill = FieldFill.INSERT)private LocalDateTime createTime;/*** 更新时间*/@ApiModelProperty("更新时间")@TableField(fill = FieldFill.INSERT_UPDATE)private LocalDateTime updateTime;/*** 创建人姓名*/@ApiModelProperty("创建人姓名")@TableField(fill = FieldFill.INSERT)private Long createUser;/*** 更新人姓名*/@ApiModelProperty("更新人姓名")@TableField(fill = FieldFill.INSERT_UPDATE)private Long updateUser;}

2.mapper
