}誰在數據庫中有這種關係：
我想在休眠查詢，顯示所有的Staff INNER JOIN RtStaffDispenser ON Staff.idstaff = RtStaffDispenser.idRtsdispenser的元素。 我該怎麼做？我知道SQL INNER JOIN，但我不知道HIBERNATE INNER JOIN

你的Rtsdispenser在rt_staff_dispenser bean中？你可以在Staff.idstaff = R上使用inner join tStaffDispenser.idrtStaffDispenser，而不是Staff.idstaff = RtStaffDispenser.Rtsdispenser。 –
反正它不起作用 –
JUNIT顯示以下錯誤：org.hibernate.hql.internal.ast.QuerySyntaxException：加入的路徑！ [from it.jack.fdd.domain.Staff內部加入RtStaffDispenser在Staff.idstaff = RtStaffDispenser.idrtStaffDispenser] –
