geoserver 常见问题笔记

1、cql查询示例，根据点查询返回code的空间查询示例

http://192.168.0.226:8080/geoserver/lgum/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=lgum:jd&cql_filter=CONTAINS(geom%2cPOINT(114.23859+22.68015))&maxFeatures=1&propertyName=JDCODE&outputFormat=json

 根据坐标查询单元网格编码

http://192.168.0.226:8080/geoserver/lgum/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=lgum:grid&cql_filter=CONTAINS(geom%2cPOINT(114.23859+22.68015))&maxFeatures=1&propertyName=GRIDCODE&outputFormat=json

 2、根据WFS更新图层属性

请求的URL：

http://192.168.0.228:8080/geoserver/wfs

POST XML参数值

 <!--       YOU PROBABLY DO NOT WANT TO RUN THIS QUERY SINCE 
       IT WILL MODIFY YOUR SOURCE DATA FILES

      This will update the type field for the tasmania_roads dataset.
      
   -->


<wfs:Transaction service="WFS" version="1.0.0"
  xmlns:topp="http://www.openplans.org/topp"
  xmlns:ogc="http://www.opengis.net/ogc"
  xmlns:wfs="http://www.opengis.net/wfs">
  <wfs:Update typeName="baum:sq_baidu">
    <wfs:Property>
      <wfs:Name>MC</wfs:Name>
      <wfs:Value>罗田社区_new</wfs:Value>
    </wfs:Property>
    <ogc:Filter>
         <ogc:PropertyIsEqualTo>
      <ogc:PropertyName>TYDZBM</ogc:PropertyName>
      <ogc:Literal>440306004009</ogc:Literal>
      </ogc:PropertyIsEqualTo>
    </ogc:Filter>
  </wfs:Update>
</wfs:Transaction>

更新图层时，遇到is read-only的解决方法：

打开geoserver管理界面，点击左侧的“”Security“”中的“”Data“”栏，点击“Rule path”中的“..w”，勾选“Grant access to any role”下面的单选框，点击保存，清理缓存，再是修改后点击提交，保存成功。
