Question

我在liferay6中有我的自定义portlet，我在数据库中插入长数据时遇到异常java.sql.BatchUpdateException: Data truncation: Data too long for column 'XXXX' at row 1

即使我在portlet-modal-hints

中提供了以下参数，也会发生这种情况

<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

任何人都可以告诉我为什么这仍然是一个错误？

任何人都可以给我一些建议吗？

Answer 1

将我的comment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。

然后你应该重新部署插件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。

Answer 2

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

您可以尝试使用属性maxlength =“4000”限制文本框或文本区域这不会让你发布超过4000个单词。

获取异常java.sql.BatchUpdateException：数据截断：列'XXXX'的数据太长
