No cache could be resolved for……. At least one cache should be provided per cache operation

报错：No cache could be resolved for 'Builder[public abstract com.example.cache.generate.Department com.example.cache.generate.DepartmentDao.selectByPrimaryKey(java.lang.Integer)] caches=[] | key='' | keyGenerator='' | cacheManager='' | cacheResolver='' | condition='' | unless='' | sync='false'' using resolver 'org.springframework.cache.interceptor.SimpleCacheResolver@4c504095'. At least one cache should be provided per cache operation.

本来@EnableCaching+@Cacheable(cacheNames={"xx"})就行了，结果……

我的天，我一直在实现类里面找错误，结果最后发现是我在接口写了一个@Cacheable忘记删除了。难受，浪费2个小时。
