Question

我正在将我的遗留应用程序从Hibernate 3.6升级到4.3。该应用程序适用于Hibernate 3.6。但是，在我将应用程序升级到Hibernate 4.3之后，我遇到了com.microsoft.sqlserver.jdbc.SQLServerException：字符串或二进制数据将被截断。

应用程序中这些实体的映射配置未经历任何更改，并且与以前相同。有问题的数据库表都没有改变。所以我现在无法意识到出了什么问题。该应用程序使用的是Spring 4.1和Java 8，MS SQL 2014是数据库。

我搜索了这个错误，人们似乎建议在多对一关系缺少hbm文件的情况下发生这种类型的问题。但是，我没有在下面的配置中看到这一点

<class name="com.mycompany.rm.pmech.common.domain.AdditionalFee"
       table="AdditionalFee">
    <id name="id" column="AdditionalFeeId" type="int">
        <generator class="identity"/>
    </id>
    <many-to-one name="station" column="stationId" class="com.mycompany.rm.pmech.common.domain.Station" />
    <many-to-one name="carGroup" column="carGroupId" class="com.mycompany.rm.pmech.common.domain.CarGroup" />
    <property name="effectiveDate" column="EffectiveDate" />
    <property name="feeType" column="FeeType" type="com.mycompany.rm.pmech.common.hibernate.types.HibernateFeeType"/>
    <property name="feeAmount" column="FeeAmount" type="com.mycompany.rm.common.types.DecimalUserType" />
    <property name="feeCalculationType" column="FeeUnit" type="com.mycompany.rm.pmech.common.hibernate.types.HibernateFeeCalculationType" />
    <property name="taxable" column="taxable" type="boolean" />
</class>

以下是我的表格外观

CREATE TABLE [[AdditionalFee](
            [AdditionalFeeId] [bigint] IDENTITY(1,1) NOT NULL,
            [CarGroupId] [int] NOT NULL,
            [StationId] [int] NOT NULL,
            [EffectiveDate] [datetime] NOT NULL,
            [FeeType] [varchar](3) NOT NULL,
            [FeeUnit] [varchar](1) NOT NULL,
            [FeeAmount] [money] NOT NULL,
            [Taxable] [bit] NOT NULL,
)

这是之前使用的配置和表，并且与hibernate 3.6一起工作正常，所以我并不怀疑它是关系映射的问题。

以下是保存实体时抛出异常的代码。

getHibernateTemplate().save(additionalFee);

以下是异常的堆栈跟踪。

非常感谢任何有助于解决问题的帮助/指示。

我有类似的问题，终于设法解决了它：在hibernate3下，我为我的enumType（Sex）制作了一个特殊的enumType。迁移到hibernate4时似乎不再需要了，所以我删除了它。一切都运行正常，但在一个非常特殊的情况下，我从sql server收到消息，数据将被截断。

使用SQL事件探查器（可能与您的SQL服务器一起安装），我设法看到实际发送到数据库的内容，并看到我的枚举类型的值太长。然后我从

更改了我的hibernate映射

    <property name="sex" column="SEX"/>

到

    <property name="sex" column="SEX">
        <type name="org.hibernate.type.EnumType">
            <param name="enumClass">ch.in4medicine.e4med.common.Sex</param>
        </type>
    </property>

一切都有效（目前）。

我身边有两个提示：

使用SQL事件探查器查看实际发送给DB的内容
检查您是否正确映射了枚举。

升级Hibernate 3.6到4.3获取com.microsoft.sqlserver.jdbc.SQLServerException：字符串或二进制数据将被截断
