1.实现思路

具体的实现思路如下：

①导入Spring Cache和Redis相关的Maven坐标

②在启动类加入@EnableCaching注解，开启缓存注解功能

③在用户端接口SetmealController的list方法上加入@Cacheable注解

/*** 条件查询** @param categoryId* @return*/@GetMapping("/list")@ApiOperation("根据分类id查询套餐")@Cacheable(cacheNames = "setmealCache",key = "#categoryId")public Result<List<Setmeal>> list(Long categoryId) {Setmeal setmeal = new Setmeal();setmeal.setCategoryId(categoryId);setmeal.setStatus(StatusConstant.ENABLE);List<Setmeal> list = setmealService.list(setmeal);return Result.success(list);}

④在管理端接口SetmealController的save、delete、update、startOrStop等方法上加入CacheEvict注解

package com.sky.controller.admin;import com.sky.dto.SetmealDTO;
import com.sky.dto.SetmealPageQueryDTO;
import com.sky.result.PageResult;
import com.sky.result.Result;
import com.sky.service.SetmealService;
import com.sky.vo.SetmealVO;
