我遇到了以下情况:

我的实体彼此相关,但是这样我就无法使用JPQL.我被迫使用原生SQL.现在我想将这些结果映射到ValueObject.要清楚,我不想得到Object array(List<Object[]>)的列表.我有6个实体,我只需要一些列.任何人都可以举例说明如何从本机查询实现这样的映射？

我经历过的教程.

我的代码:

@SqlResultSetMapping(
    name = "findAllDataMapping",
    classes = @ConstructorResult(
            targetClass = MyVO.class,
            columns = {

                    @ColumnResult(name = "userLastName"),
                    @ColumnResult(name = "id"),
                    @ColumnResult(name = "packageName")
            }
    )
)

@NamedNativeQuery(name = "findAllDataMapping",
    query = "SELECT " +
            "    u.first_name as userFirstName, " +
            "    u.last_name as userLastName, " +
            "    i.id as id, " +
            "    s.title as packageName, " +
            "FROM " +
            "    invoice as i " +
            "JOIN user …
