休眠：无法从结果集中读取列值：无法转换为内部表示

Question

我正在尝试从数据库中获取值。我已经成功配置休眠。下面是我的 hbm 文件和 pojo 类。

<class name="UserMasterBean" table="EMPLOYEE_MASTER">
    <id name="Id" type="long">
        <column name="EMP_ID" length="10" />
        <generator class="assigned" />
    </id>
    <property name="FirstName" type="string">
        <column name="EMP_FIRST_NAME" length="30" not-null="true" />
    </property>
    <property name="SecondName" type="string">
        <column name="EMP_SECOND_NAME" length="30" />
    </property>
    <property name="LastName" type="string">
        <column name="EMP_LAST_NAME" length="30" />
    </property>

    <property name="empDob" type="date">
        <column name="EMP_DOB" length="7" not-null="true" />
    </property>
    <property name="empDoj" type="date">
        <column name="EMP_DOJ" length="7" not-null="true" />
    </property>
    <property name="empPermAdd1" type="string">
        <column name="EMP_PERM_ADD1" length="50" not-null="true" />
    </property>
<!--Other Properties removed-->

我面临以下错误。

Sep 04, 2013 11:50:19 AM org.hibernate.type.NullableType nullSafeGet
INFO: could not read column value from result set: EMP1_0_; Fail to convert to internal           representation

Sep 04, 2013 11:50:19 AM org.hibernate.util.JDBCExceptionReporter logExceptions
SEVERE: Fail to convert to internal representation

我没有发现我的代码有什么问题。

我查询为

String hql = "from UserMasterBean";
    List empList = attendance.getList(hql, factory);

对于其他类它的工作

Answer 1

当为不是数字的字符串表示形式的 VARCHAR 值调用 getInt（或其他一些数字类型）时，将引发此错误。如果 VARCHAR 列包含“BOB”并且您对该列调用 getInt，则会收到此错误。
