Java 休眠 java.lang.IllegalArgumentException: 未知参数位置: 1

Question

这是我的查询方法：

@Query(value = "select new com.twognation.hub.dto.GameDTO(game.id, game.name, game.active, game.description, game.coverImage, game.logo, game.backgroundImage, game.featuredImage, game.characterImage, game.smallCoverImage, count(tournament.id) as tournamentCount) from Game game left join Tournament tournament on game.id=tournament.game where lower(game.name) like '%:name%' group by game.id order by tournamentCount desc, game.id",
                countQuery = "select count(1) from Game game left join Tournament tournament on game.id=tournament.game where lower(game.name) like '%:name%' group by game.id order by tournamentCount desc, game.id")
Page<GameDTO> findAllOrderByTournamentCount(@Param("name") String name, Pageable page);

当我调用此方法时出现此错误：

Answer 1

这个：

'%:name%'

在 JPA 中只是一个原生字符串，要解决此问题，您可以使用 CONCAT 运算符，如下所示：

CONCAT('%', :name, '%')

稍后将转换为 '%some_value%' 例如

Answer 2

您似乎对 like 有疑问。

而不是

'%:name%'

做：

%:name%
