效果图

 

数据库设计

轮播图表

DROP TABLE IF EXISTS `banner`;
CREATE TABLE `banner` (
  `bannerId` int(11) NOT NULL AUTO_INCREMENT,
  `bannerUrl` longtext,
  `bannerDesc` varchar(255) DEFAULT NULL,
  `bannerTypeId` int(11) DEFAULT NULL,
  PRIMARY KEY (`bannerId`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8mb4;

轮播图类型表

DROP TABLE IF EXISTS `banner_type`;
CREATE TABLE `banner_type` (
  `bannerTypeId` int(11) NOT NULL AUTO_INCREMENT,
  `bannerTypeName` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`bannerTypeId`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8mb4;

实体类设计

轮播图

package jkw.pojo;

import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import lombok.Data;

import java.io.Serializable;

/**
 * 轮播图
 */
@Data
public class Banner implements Serializable {
    @TableId
    private Integer bannerId;
    private String bannerUrl;//图片
    private String bannerDesc;//描述

    private Integer bannerTypeId;//类型
    @TableField(exist = false)
    private BannerType bannerType;
}

轮播图类型

package jkw.pojo;

import com.baomidou.mybatisplus.annotation.TableId;
import lombok.Data;

import java.io.Serializable;

/**
 * 轮播图类型
 */
@Data
public class BannerType implements Serializable {
    @TableId
    private Integer bannerTypeId;
    private String bannerTypeName;//类型名
}

Mapper层开发

BannerTypeMapper

package jkw.mapper;
