原生SQL方法

設(shè)置@Query的屬性為nativeQuery = true

@Query(value = "select u.* from Article u where u.title =  ? ", nativeQuery = true)

:title 、?1 匹配第一個參數(shù)title

    @Query(value = "select u.* from Article u where u.title = :title ", nativeQuery = true)
    List<Article> queryArticleList(String title) ;

    @Query(value = "select u.* from Article u where u.title = ?1 ", nativeQuery = true)
    List<Article> queryArticleList(String title) ;
