原因分析

sql语法手误。1?这地方写错了，应该是?1。这在敲代码的时候，手速一旦稍有不慎，就会导致前后顺序颠倒，而导致输入错误。这个虽然说是“低级错误”，但是错误搞起来，确实有时候很难想到这个你从来不会认为出错的地方。

@Query(value = "select * from `user` where `username` = 1? limit 1", nativeQuery = true)  def findByUsername(username: String): User

解决方案

@Query(value = "select * from `user` where `username` = ?1 limit 1", nativeQuery = true)  def findByUsername(username: String): User
