我试图将我的应用程序从 Hibernate 3.2 升级到 Hibernate 3.5.6，但我得到了以下以前没有的异常：

我在这个页面堆栈溢出上发现它可能是缓存的问题。我仍在使用ehcache，没有改变任何东西。所以我尝试禁用它，但我仍然遇到问题。
此问题发生在此方法中
@Transactional
public void createLocalEntriesForEmployeeType(List<RemotePhone> dataToBeAddedLocally, Integer employeeId) {
{
for (RemotePhone remote : dataToBeAddedLocally) {
ExternalDetails externalDetails = new ExternalDetails();
externalDetails.setRemoteId(remote.getRemoteId().toString());
externalDetails.setLastUpdated(remote.getUpdateDate());
EmployeePhoneNumber localPhone = createLocalPhone(remote);
employeeService.savePhoneNumber(localPhone, employeeId);
ExternalPhoneDetails externalPhoneDetails = new externalPhoneDetails();
externalPhoneDetails.setPayrollDataType(localPhone);
externalPhoneDetails.setExternalDetails(externalDetails);
externalDao.save(externalPhoneDetails);
}
}
方法 savePhoneNumber 是：
@Transactional
public void savePhoneNumber(EmployeePhoneNumber phoneNumber, Integer employeeId) {
validationService.assertValid(phoneNumber, "employeePhoneNumber");
Employee employee = getEmployee(employeeId);
employee.getPhoneNumbers().add(phoneNumber);
}
映射是：
<class
name="Employee"
table="EMPLOYEE"
lazy="true"
>
<id
name="id"
column="EMPLOYEEID"
type="java.lang.Integer"
unsaved-value="undefined"
>
<generator class="sequence">
<param name="sequence">EMPLOYEEID_SEQ</param>
</generator>
</id>
<property name="firstName" column="FIRSTNAME" type="java.lang.String"/>

</id>
<many-to-one

cascade="save-update, delete"
/>
<many-to-one

</class>
我找到了一种通过在调用 employeeService.savePhoneNumber() 后刷新 hibernateSession 来解决此问题的方法，但我不喜欢此解决方案，并且它曾经在 Hibernate 3.2 中正常工作。这是hibernate 3.5中的错误还是我想升级时需要更改的东西？
谢谢
