带Projection的Spring JPA本机查询给出“ ConverterNotFoundException”

借助弹簧数据，您可以削减中间人并简单地定义

public interface Idsonly {  Integer getId();  String getOtherId();}

并使用本机查询，例如；

@Query(value = "Id, OtherId from TestTable where CreationDate > ?1 and Type in (?2)", nativeQuery = true)    public Collection<IdsOnly> findEntriesAfterDate(Date creationDate, List<Integer> types);
