迁移到Hibernate 6后中断的查询

当更新到Hibernate 6(来自5.6)时,一些现有的查询会被破坏。
例如,在5.6中执行以下查询工作正常:

@Query(
      "SELECT new Position(p, CASE WHEN p.sourceSetId IS NULL THEN p.sourceSetName ELSE s.name END as sourceSetName, pos.optimizedDisplayOrder) FROM Position p "
          + "LEFT JOIN Position pos ON pos.projectId = p.projectId AND pos.positionId = p.sourceSetPositionId "
          + "LEFT JOIN Manufacturer m ON p.optimizedItem.manufacturer.manufacturerId = m.manufacturerId "
          + "LEFT JOIN Set s ON p.sourceSetId = s.setId AND p.projectId = s.projectId "
          + "WHERE p.setId = :setId AND p.projectId = :projectId "
          + "AND (UPPER(p.optimizedItem.code) LIKE UPPER(CONCAT('%', :searchParam, '%')) "
          + "OR UPPER(m.name) LIKE UPPER(CONCAT('%', :searchParam, '%')) "
          + "OR UPPER(p.optimizedItem.description) LIKE UPPER(CONCAT('%', :searchParam, '%')))")

但导致6中的以下错误:

我读了migration guide,但找不到对此的解释。
我错过什么了吗?

据我所知,从查询您返回的DTO具有相同的名称作为实体,您正在查询。你必须以某种方式区分它们。请使用DTO声明的完全限定名:

@Query(
      "SELECT new com.your.package.name.Position(p, CASE WHEN p.sourceSetId IS NULL THEN p.sourceSetName ELSE s.name END as sourceSetName, pos.optimizedDisplayOrder) FROM Position p "
          + "LEFT JOIN Position pos ON pos.projectId = p.projectId AND pos.positionId = p.sourceSetPositionId "
          + "LEFT JOIN Manufacturer m ON p.optimizedItem.manufacturer.manufacturerId = m.manufacturerId "
          + "LEFT JOIN Set s ON p.sourceSetId = s.setId AND p.projectId = s.projectId "
          + "WHERE p.setId = :setId AND p.projectId = :projectId "
          + "AND (UPPER(p.optimizedItem.code) LIKE UPPER(CONCAT('%', :searchParam, '%')) "
          + "OR UPPER(m.name) LIKE UPPER(CONCAT('%', :searchParam, '%')) "
          + "OR UPPER(p.optimizedItem.description) LIKE UPPER(CONCAT('%', :searchParam, '%')))")
