开发环境搭建

启动类编写

src/main/java/com/XXX/reggie/ReggieApplication.java

package com.yjq.reggie;import lombok.extern.slf4j.Slf4j;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@Slf4j //直接可使用log日志@SpringBootApplicationpublic class ReggieApplication {public static void main(String[] args) {SpringApplication.run(ReggieApplication.class,args);log.info("项目启动成功..."); //测试项目启动}}

配置类编写 完成MVC框架静态资源映射

config/WebMvcConfig

package com.yjq.reggie;import lombok.extern.slf4j.Slf4j;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@Slf4j //直接可使用loge@SpringBootApplicationpublic class ReggieApplication {public static void main(String[] args) {SpringApplication.run(ReggieApplication.class,args);log.info("项目启动成功...");}}

再次启动查看日志是否成功，然后访问页面http://localhost:8080/backend/index.html

ps:不管用的看看放的路径是否正确，启动类要在最外层

后台登录功能

需求分析

http://localhost:8080/backend/page/login/login.html打开登陆页面
按下F12，点击登录按钮，发送请求并题交参数

package com.yjq.reggie.common;import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;import lombok.extern.slf4j.Slf4j;import org.apache.ibatis.reflection.MetaObject;import org.springframework.stereotype.Component;import java.time.LocalDateTime;@Slf4j@Componentpublic class MyMetaObjectHandler implements MetaObjectHandler {/*** 插入操作，自动填充* @param metaObject*/@Overridepublic void insertFill(MetaObject metaObject) {log.info("公共字段自动填充[insert]...");log.info(metaObject.toString());metaObject.setValue("createTime", LocalDateTime.now());metaObject.setValue("updateTime", LocalDateTime.now());metaObject.setValue("createUser", new Long(1));metaObject.setValue("updateUser", new Long(1));}/*** 更新操作，自动填充* @param metaObject*/@Overridepublic void updateFill(MetaObject metaObject) {log.info("公共字段自动填充[update]...");log.info(metaObject.toString());metaObject.setValue("updateTime", LocalDateTime.now());metaObject.setValue("updateUser", new Long(1)); }}

功能完善

回显数据涉及两个表的数据，到DishService中自定义get方法（获取dish表中基本信息以及dish_flavor中对应的口味信息）

这里使用DishDto为返回对象类型，与页面数据对应

// 根据dishId查询 菜品信息和口味信息public DishDto getByDishIdWithFlavor(Long dishId); /*** 根据id查询菜品信息和对应的口味信息* @param dishId* @return*/@Overridepublic DishDto getByDishIdWithFlavor(Long dishId) {// 只是关联查询两张表，没有涉及事务，不用加 @Transactional// 从dish表中查询 菜品的基本信息Dish dish = this.getById(dishId);DishDto dishDto = new DishDto();BeanUtils.copyProperties(dish,dishDto);// 从dish_flavor表查询 当前菜品对应的口味信息LambdaQueryWrapper<DishFlavor> queryWrapper = new LambdaQueryWrapper<>();queryWrapper.eq(DishFlavor::getDishId,dishId);List<DishFlavor> list = dishFlavorService.list(queryWrapper);dishDto.setFlavors(list);return dishDto;} /*** 根据id查询菜品信息和对应的口味信息* @param id* @return*/@GetMapping("/{id}")public Result<DishDto> get(@PathVariable Long id){DishDto dishDto = dishService.getByDishIdWithFlavor(id);return Result.success(dishDto);}

套餐管理功能

新增套餐功能

需求分析

数据模型

代码开发

SetmealDish 套餐餐品

package com.yjq.reggie.entity;import com.baomidou.mybatisplus.annotation.FieldFill;import com.baomidou.mybatisplus.annotation.TableField;import lombok.Data;import java.io.Serializable;import java.math.BigDecimal;import java.time.LocalDateTime;/*** 套餐菜品关系*/@Datapublic class SetmealDish implements Serializable {private static final long serialVersionUID = 1L;private Long id;//套餐idprivate Long setmealId;//菜品idprivate Long dishId;//菜品名称 （冗余字段）private String name;//菜品原价private BigDecimal price;//菜品的份数private Integer copies;//排序private Integer sort;@TableField(fill = FieldFill.INSERT)private LocalDateTime createTime;@TableField(fill = FieldFill.INSERT_UPDATE)private LocalDateTime updateTime;@TableField(fill = FieldFill.INSERT)private Long createUser;@TableField(fill = FieldFill.INSERT_UPDATE)private Long updateUser;//是否删除private Integer isDeleted;}

SetmealDto 继承 Setmeal套餐的基本属性，
另外根据前端页面需求数据添加了特有属性

package com.yjq.reggie.dto;import com.yjq.reggie.entity.Setmeal;import com.yjq.reggie.entity.SetmealDish;import lombok.Data;import java.util.List;@Datapublic class SetmealDto extends Setmeal {//新增套餐中自选菜品的集合private List<SetmealDish> setmealDishes;//设置分页查询页面的套餐分类名称private String categoryName;}

接口和控制层省略…

---

1-2.套餐分类和菜品分类的数据获取（CategoryController中处理过）
3.在DishController中

/*** 套餐管理/新增套餐/* 添加菜品功能中根据套餐id查询相应的菜品* @param dish* @return*/@GetMapping("/list")public Result<List<Dish>> list(Dish dish){//构造条件查询LambdaQueryWrapper<Dish> queryWrapper = new LambdaQueryWrapper<>();//等值查询queryWrapper.eq(dish.getCategoryId() != null,Dish::getCategoryId,dish.getCategoryId());//必须是起售的菜品才显示queryWrapper.eq(Dish::getStatus,1);//排序条件：根据sort升序排，根据更新时间降序排queryWrapper.orderByAsc(Dish::getSort).orderByDesc(Dish::getUpdateTime);List<Dish> dishList = dishService.list(queryWrapper);return Result.success(dishList);}

4-5.图片上传下载也已经处理过了

6.需要自定义保存方法
（原因：只操作setmeal表，套餐中的菜品信息无法保存）
在SetmealService中自定义保存方法，调用setmeal和seatmeal_dish表

/*** 新增套餐，同时需要保存套餐和菜品的关联关系* @param setmealDto*/@Transactionalpublic void saveWithDish(SetmealDto setmealDto) {//保存套餐的基本信息，操作setmeal，执行insert操作this.save(setmealDto);//保存套餐和菜品的关联关系，操作setmeal_dish，执行insert操作List<SetmealDish> setmealDishes = setmealDto.getSetmealDishes();setmealDishes.stream().map((item)->{//setmealDto.getId()就是setmeal表中每次创建一个新的套餐分类自动生成的id//setSetmealId是SetmealDish套餐菜品关系中的setmealId属性，对应setmeal_dish表中的setmeal_id//新增套餐下的自选菜品的每个setmeal_id都会在setmeal表中的id中找到对应，大家想不通的去数据库看这两个表item.setSetmealId(setmealDto.getId());return item;}).collect(Collectors.toList());//保存套餐和菜品的关联信息，操作setmeal_dish,执行insert操作setmealDishService.saveBatch(setmealDishes);}
