Data Truncation Exception不打印列名

标签: java sql sql-server hibernate truncate

我正在使用Hibernate 3.0和SQL Server 2008。

我的问题是,每当发生数据截断异常时,它都不会显示列名,这会导致此异常。它都没有显示使用实际值触发的查询。

例如,我有以下POJO:

Teacher.java

private long id;
private String name;

// getter-setter of both

name字段已映射到name列。

name列的数据类型为varchar(50)

现在,如果我尝试添加Teacher的记录,其名称的字符串包含超过50个字符(session.save(teacher)),则会给出以下异常:

如您所见,上述异常并未提供与列或输入数据相关的任何类型的通知。

我找到了以下链接:http://www.cereslogic.com/pages/2008/06/10/use-hibernate-validators-to-find-nasty/

但它使用注释。我没有使用注释,而是映射文件。

我也试过处理异常&以下内容:

dataTruncation.getIndex();
dataTruncation.getDataSize();
dataTruncation.getTransferSize();

但那些也没有帮助,因为他们都返回-1。

有人可以建议我适当的方式吗?
