我在 liferay6 中有我的自定义 portlet，在将长数据插入数据库时​​遇到异常java.sql.BatchUpdateException: Data truncation: Data too long for column 'XXXX' at row 1

即使我在portlet-modal-hints

<field name="advurl" type="String">
    <hint name="max-length">4000</hint>
</field>

这是抛出错误的列中的字符串：http://www.coderanch.com/t/435635/java/java/Regular-expression-check-specific-special

谁能告诉我为什么这仍然会引发错误？

将我的评论转换为答案以解决此问题:-)

您应该在portal-model-hints.xml文件更改后重建服务。

然后您应该重新部署插件 portlet 以使更改生效。

因此，请在执行上述步骤后检查数据库列是否已更新。

当您使用 service.xml 创建的表（字段长度）与您提交的不同时，会出现此错误。

您可以尝试使用属性 maxlength="4000" 限制您的文本框或文本区域，这不会让您发布超过 4000 个字。
