增加和修改部門返回的值為NULL，一直報Could not create and/or set value back on to object，求助
評論和問答區(qū)的方法都試過了。。。之前只有修改員工的部門會返回空值，后來連增加員工信息的部門也會變成空。在數(shù)據(jù)庫上輸入dno能在表單查到，在表單修改就為空，jsp頁面也沒有寫錯:<td>所屬部門:</td>
<td><s:select name="department.did" list="list" listKey="did" listValue="dname" headerKey="" headerValue="----請--選--擇----"/></td>
下面是控制臺報的錯:
DAO中查詢所有部門方法執(zhí)行了。。。Hibernate:
??? select??????? department0_.did as did0_,??????? department0_.pname as pname0_,??????? department0_.introduction as introduc3_0_????
from???????
department department0_

這個問題困擾了我好久，百度一下發(fā)現(xiàn)好多人都有這個問題，本來以為是spring3的getHibernateTimplate().find()方法過期了，可是評論區(qū)有用spring4的還是報同樣的問題，希望解決的大佬回復一下
