System.out.println(xuqiuForm.getName());

xuqiu.setType(t);

System.out.println(xuqiuForm.getType());



xuqiu.setTypeid(Integer.getInteger(xuqiuForm.getType()));

xuqiu.setXuqiu(xuqiuForm.getXuqiu());

System.out.println(xuqiuForm.getXuqiu());

xuqiu.setFdate(xuqiuForm.getFdate());

System.out.println(xuqiuForm.getFdate());

xuqiu.setGdate(xuqiuForm.getGdate());

System.out.println(xuqiuForm.getGdate());

xuqiu.setState(Integer.getInteger(xuqiuForm.getState()));

System.out.println(xuqiuForm.getState());



try {

this.ixuqiudao.Save(xuqiu);

} catch (Exception e) {

// TODO 自动生成 catch 块

e.printStackTrace();

}



typeid为null  但是我System.out显示了值

尝试把你的pojo写成这样，在Type 上我添加了一个方便的方法 addXuqiu。另外，你的cascade控制在one端，所以保存时候只要保存one端，one端所依赖的另一端就自动保存了。
