這篇文章主要講解了“spring命名出現(xiàn)No property user found for type怎么解決”，文中的講解內(nèi)容簡單清晰，易于學(xué)習(xí)與理解，下面請大家跟著小編的思路慢慢深入，一起來研究和學(xué)習(xí)“spring命名出現(xiàn)No property user found for type怎么解決”吧！
如果命名不正確會(huì)出現(xiàn)
No property user found for type
public interface UserRepository extends JpaRepository<User, Long>{
User findByName(String userName);
}
可以看出實(shí)體類字段是userName,而repository卻是findByName!改為findByUserName就好了
