org.hibernate.PropertyAccessException：调用getter时发生IllegalArgumentException

Question

我尝试将我的应用程序从Hibernate 3.2升级到Hibernate 3.5.6，然后我得到以下我以前没有的异常：

我在此页stack overflow上发现它可能是缓存的问题。我还在使用ehcache，没有改变它。所以我试图禁用它，我仍然有问题。

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);
    }
}

savePhoneNumber方法是：

@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">EXTERNAL_PHONE_NUMBER_DETAILS_ID_SEQ</param>
        </generator>
    </id>

    <many-to-one
        name="externalDetails"
        column="EXTERNAL_DETAILS"
        class="ExternalDetails"
        cascade="save-update, delete"
    />

    <many-to-one
        name="payrollDataType"
        column="PHONE_NUMBER"
        class="EmployeePhoneNumber"
        cascade="save-update, delete"
    />
</class>

我找到了一种通过在调用employeeService.savePhoneNumber（）之后刷新hibernateSession来解决这个问题的方法，但是我不喜欢这个解决方案，它曾经和Hibernate 3.2一起使用。 这是hibernate 3.5中的一个错误，还是我想要升级时需要更改的内容？

谢谢
