Has always been this problem these days, Spring boot startup error, scanning is no need to register the class, today finally found that Spring boot startup classes need on the scanning of the upper directory, so you can scan to class or subclass need to register at the same level, but I found a other problem on the net, some say write directly with @ ComponentScan need scan class path, but I haven't successful test, don't know why, help to look at the trouble! Just contact spring boot first thank you,

Below is I want to scan the dao and the service, but has been an error, since the start of a see be wrong ReadingListRepository didn't scan to class, this class inherits JpaRepository

This annotation scanning the bag under the class, and at the same level of class package, if there are other different parent-child bag, can use basePackage assigned specific package, recommend will launch a class in the top of the bag

ReadingListRepository this into ordinary Java classes, do not use interface, then add @ in the class above Service
