篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了插入空的，通过地理服务器将请求文本/ xml发送到postgis整数字段中相关的知识，希望对你有一定的参考价值。

我正在尝试通过geoserver将属性类型为整数的几何插入到Postgis表中。客户端基于Openlayers，请求使用WFS模块。如果我在该字段中输入数字就可以了，但是当尝试发送一个空字段时，我会返回parsing failed for integer: java.lang.stringindexoutofboundsexeptionajax请求看起来像这样：

   url: source.url,
   data: serializer.serializeToString(node),
   contentType: 'text/xml'

这是节点：

<Transaction service=​"WFS" version=​"1.1.0" xsi:schemaLocation=​"http:​/​/​www.opengis.net/​wfs http:​/​/​schemas.opengis.net/​wfs/​1.1.0/​wfs.xsd">​
<Insert>​
<typetests fid=​"0febc253-56de-46f3-8e55-5c2cb46ef9c0">​<geom>​…​</geom>
​<ttextmax8>​​</ttextmax8>​
<ttextareamax256>​​</ttextareamax256>​
<tdropdown>​​</tdropdown>​

<tinteger>​​</tinteger>​
<tdecimal>​​</tdecimal>

​<tdate>​2020-04-02​</tdate>
​<ttime>​10:53:44​</ttime>​
<ttimestamp>​2020-04-02T10:53:44​</ttimestamp>​
<timage>​​</timage>
​<tcolor>​#000000​</tcolor>​
<temail>​​</temail>​
<tulr>​​</tulr>​
<tcheckbox>​0​</tcheckbox>
​</typetests>​
</Insert>
</Transaction>

有人遇到这个问题并有解决方案吗？

从地理服务器登录如下：

其他信息：如果我从同一客户端编辑一行，并在整数字段中插入一个数字，则将其保存（一切正常），然后删除其仍然有效并被接受的数字。 Pgadmin再次显示[null]。更新时的事务与插入看起来不同：

答案

我的解决方案是不要在值为空的地方插入任何东西。

以上是关于插入空的，通过地理服务器将请求文本/ xml发送到postgis整数字段中的主要内容，如果未能解决你的问题，请参考以下文章
