Hibernate Criteria - 从select中排除groupProperty

Question

我想在第二个标准上使用hibernate条件对象作为子查询，如下所示：

    DetachedCriteria latestStatusSubquery = DetachedCriteria.forClass(BatchStatus.class);
    latestStatusSubquery.setProjection(Projections.projectionList()
            .add( Projections.max("created"), "latestStatusDate")
            .add( Projections.groupProperty("batch.id"))
    );

    DetachedCriteria batchCriteria = DetachedCriteria.forClass(BatchStatus.class).createAlias("batch", "batch");
    batch.add( Property.forName( "created" ).eq( latestStatusSubquery ) );

问题是添加groupProperty会自动将该属性添加到subselect查询的select子句中，我找不到任何方法来阻止这种情况发生。

结果当然是DB错误，因为子查询返回的值太多了。

有没有人知道解决这个问题？

尝试以下示例，

DetachedCriteria subquery = DetachedCriteria.forClass(CustomerCommentsVO.class, "latestComment"); 
            subquery.setProjection(Projections.max("latestComment.commentId")); 
            subquery.add(Expression.eqProperty("latestComment.prospectiveCustomer.prospectiveCustomerId", "comment.prospectiveCustomer.prospectiveCustomerId"));

 objCriteria = objSession.createCriteria(CustomerCommentsVO.class,"comment");
            objCriteria.add(Subqueries.propertyEq("comment.commentId", subquery)); 
List lstComments = objCriteria.list();
