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

報錯：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.

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

我的天，我一直在實現類里面找錯誤，結果最后發現是我在接口寫了一個@Cacheable忘記刪除了。難受，浪費2個小時。
