二.新增菜品

1.图片上传

这里采用了阿里云oss对象存储服务

1. application.yml

  alioss:endpoint: ${sky.alioss.endpoint}access-key-id: ${sky.alioss.access-key-id}access-key-secret: ${sky.alioss.access-key-secret}bucket-name: ${sky.alioss.bucket-name}

2. OssConfiguration 用来初始化,具体的配置文件在common中properties中

package com.sky.config;import com.sky.properties.AliOssProperties;
import com.sky.utils.AliOssUtil;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** 阿里云OSS配置*/
@Configuration
@Slf4j
public class OssConfiguration {@Bean@ConditionalOnMissingBean//当容器里没有指定的Bean的情况下创建该对象public AliOssUtil aliOssUtil(AliOssProperties aliOssProperties) {log.info("初始化阿里云OSS配置");return new AliOssUtil(aliOssProperties.getEndpoint(),aliOssProperties.getAccessKeyId(),aliOssProperties.getAccessKeySecret(),aliOssProperties.getBucketName());}
}

3. CommonController.java

package com.sky.controller.admin;import com.sky.constant.MessageConstant;
import com.sky.result.Result;
import com.sky.utils.AliOssUtil;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;import java.io.IOException;
import java.util.UUID;@Api(tags = "通用接口")
@RestController
@RequestMapping("/admin/common")
@Slf4j
public class CommonController {@Autowiredprivate AliOssUtil aliOssUtil;/*** 文件上传** @param file* @return*/@PostMapping("/upload")@ApiOperation("文件上传")public Result<String> upload(MultipartFile file) {log.info("文件上传:{}", file);try {String originalFilename = file.getOriginalFilename();//截取文件后缀String suffix = originalFilename.substring(originalFilename.lastIndexOf("."));String objectName = UUID.randomUUID().toString() + suffix;String url = aliOssUtil.upload(file.getBytes(), objectName);return Result.success(url);} catch (IOException e) {log.error("文件上传失败: {}", e.getMessage(), e);}return Result.error(MessageConstant.UPLOAD_FAILED);}
}

2.具体新增菜品

1. DishController

package com.sky.controller.admin;import com.sky.dto.DishDTO;
import com.sky.result.Result;
import com.sky.service.DishService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;/*** 菜品管理*/
@RestController
@RequestMapping("/admin/dish")
@Slf4j
@Api(tags = "菜品管理")
public class DishController {@Autowiredprivate DishService dishService;/*** 新增菜品*/@PostMapping@ApiOperation("新增菜品")public Result save(@RequestBody DishDTO dishDTO) {log.info("新增菜品:{}", dishDTO);dishService.saveWithFlavor(dishDTO);return Result.success();}
}

2. DishService

public interface DishService {/*** 新增菜品和口味*/void saveWithFlavor(DishDTO dishDTO);
}

3. DishServiceImpl

package com.sky.service.impl;import com.baomidou.mybatisplus.core.batch.MybatisBatch;
import com.sky.dto.DishDTO;
import com.sky.entity.Dish;
import com.sky.entity.DishFlavor;
import com.sky.mapper.DishFlavorMapper;
import com.sky.mapper.DishMapper;
import com.sky.service.DishService;
import lombok.extern.slf4j.Slf4j;
import org.apache.ibatis.session.SqlSessionFactory;
import org.springframework.beans.BeanUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;import java.util.Arrays;
import java.util.List;@Service
@Slf4j
public class DishServiceImpl implements DishService {@Autowiredprivate DishMapper dishMapper;@Autowiredprivate SqlSessionFactory sqlSessionFactory;/*** 新增菜品和口味*/@Override@Transactionalpublic void saveWithFlavor(DishDTO dishDTO) {//向菜品表插入一条数据Dish dish = new Dish();BeanUtils.copyProperties(dishDTO, dish);dishMapper.insert(dish);dishMapper.selectById(dish.getId()); // 获取插入后的主键值//获取菜品idLong dishId = dish.getId();//向口味表插入多条数据List<DishFlavor> flavors = dishDTO.getFlavors();if (flavors != null && !flavors.isEmpty()) {// 设置 dishIdflavors.forEach(flavor -> flavor.setDishId(dishId));// 批量插入MybatisBatch<DishFlavor> mybatisBatch = new MybatisBatch<>(sqlSessionFactory, flavors);MybatisBatch.Method<DishFlavor> method = new MybatisBatch.Method<>(DishFlavorMapper.class);mybatisBatch.execute(method.insert());}}
}

4. DishMapper

@Mapper
public interface DishMapper extends BaseMapper<Dish> {
}

5. DishFlavorMapper

@Mapper
public interface DishFlavorMapper extends BaseMapper<DishFlavor> {}

6. 注意需要在实体类中添加主键自增策略，也可以配置主键全局自增，如果还是默认的雪花算法，需要把数据库重建
