org.hibernate.PropertyAccessException：调用setter时发生IllegalArgumentException

Question

我在尝试获取实体列表时得到]，这是1-n关联的n侧。

这是例外

PropertyAccessException

DB

org.hibernate.PropertyAccessException: IllegalArgumentException occurred while calling setter of com.upload.model.UploadFeeEntryItem.uploadFile

DAO：

CREATE TABLE UPLOAD_FEE_ENTRY (
UPLOAD_ID NUMBER NOT NULL PRIMARY KEY,
NUMBER_OF_RECORDS NUMBER(4,0),
STATUS VARCHAR2(50 BYTE),
USER_ID VARCHAR2(50 BYTE),
UPLOAD_DATE_TIME TIMESTAMP(6)
);

ROUTING_NUMBER  VARCHAR2(50 BYTE),
CONSTRAINT FK_UPLOAD_FEE_ENTRY
    FOREIGN KEY (UPLOAD_ID)
    REFERENCES UPLOAD_FEE_ENTRY(UPLOAD_ID)
);

Java类UploadEntry：

@Transactional(propagation = Propagation.REQUIRED)
public List<UploadFeeEntryItem> getAllFileRecords(int pageNumber,int pageSize, Long fileId) throws DAOException 
{
    log.debug("get getAllFileRecords records");
    try {

        List<UploadFeeEntryItem> instance = (List<UploadFeeEntryItem>) sessionFactory.getCurrentSession().createCriteria("com.wf.fx.ibh.upload.model.UploadFeeEntryItem").list();

        return instance;
    } catch (Exception e) {
        e.printStackTrace();
        throw new DAOException("Exception in " + this.getClass() + ", method - getAllFileRecords() ", e);
    }
}

这是hbm文件：
