一、导入Maven依赖：

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-cache</artifactId>
	<version>2.7.3</version>
</dependency>

二、实现思路：

三、代码开发：

@Cacheable(cacheNames = "setmealCache",key = "#categoryId") 

@CacheEvict(cacheNames = "setmealCache",key = "#setmealDTO.categoryId")//key: setmealCache::100
 
@CacheEvict(cacheNames = "setmealCache",allEntries = true)
