休眠更新父表和它的子表，但不工作porp？

Question

在这里，我有两个JPA类：的TimeSheet和TimeSheetDetails

在这种情况下，我有时间表的更新用一个麻烦，而更新用的时间表（主表）顺畅更新，但时间表细节（子表）生成新的行，而不是更新用和链接表还更新了新的价值观.....的

这里什么是重新

1）TimeSheet.java

Answer 1

的问题是在日是行：

obj.setTimesheetDetails(objTimeSheet.getTimesheetDetails()); 

你应该做同样的更新孩子到你正在做什么来更新父母。即：

obj.getTimesheetDetails().setTsd_Date(objTimeSheet.getTimesheetDetails().getTsd_Date);
