java - postgres中的array_agg函数，在java中使用时不返回任何记录/数据？

Question

我有这样的查询

select sender_id, ARRAY_AGG(receiver_id) as receiver_id from senderTbl group by sender_id

当我在pgAdmin中执行此查询时，它运行良好并返回像此 图像一样的记录 但是当从 java 代码调用时它不起作用

String query = "select sender_id, ARRAY_AGG(receiver_id) as receiver_id from senderTbl group by sender_id"
Query q = session.createSQLQuery(query);
 List li = new LinkedList();
 li = q.list();
