我需要根据location/city、地区、状态、包裹搜索客户详细信息。

我使用内部联接来联接 Cities 、 Regions 、 Paytypes 、 ActiveUser 表。

但是我收到了重复的数据行。

有人可以为我的问题提供解决方案吗？

Answer 1

我添加了这个声明。

queries.setResultTransformer( DistinctRootEntityResultTransformer.INSTANCE ) ;

Answer 2

测试在你的休眠条件中添加这个，在调用 list() 之前：

queries.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);

此致
