JPA findBy field ignore case
Try something like this:
List<User> findByNameInIgnoreCase(List<String> userNames);
As I understood IgnoreCase is not supported with In key, so I changed code this way:
@Repositorypublic interface UserRepository { @Query("select user from SysUser user where upper(name) in :userNames") List<SysUser> findByNameIgnoreCaseIn(@Param("userNames") List<String> userNames);}and previously upper case userNames values.
