4. service.xx类impl

讯享网@Autowired private RedisTemplate redisTemplate;

查

@Cacheable(cacheNames = "xxx",key = "'getEmpList'")

讯享网@Cacheable(cacheNames = "xxx",key = "'emp:id'+#id") 

增改

讯享网

@CachePut(cacheNames = "xxx",key = "'emp:id'+#shopping.id")

删

讯享网@CacheEvict(cacheNames = "xxx",key = "'emp:id'+#id")
