我正在为 Geoserver wms 层创建 SLD。 SLD 验证无误，但图标不会显示在地图中。我正在使用基于属性的规则来比较字符串，以便为正确的功能显示正确的图像。这是我的代码，感谢您的帮助！

【问题讨论】：

【参考方案1】：

我知道这篇文章很旧，但也许有人会从我的回答中受益。

我没有成功使用相对图像路径，所以我转而使用 URL 路径。

将图像放入 $GEOSERVER_DATA_DIR/styles 并使用 http://localhost:8081/geoserver/styles/some_image.png 引用它

例如

<ExternalGraphic>
  <OnlineResource xlink:type="simple" xlink:href="http://localhost:8081/geoserver/styles/some_image.png"/>
  <Format>image/png</Format>
</ExternalGraphic>

【讨论】：

非常感谢。我无法以任何其他方式访问图像。【参考方案2】：

不错的答案，但假设地理服务器实例在端口 8080 上工作，您需要将 8081 更改为 8080

【讨论】：

【参考方案3】：

你可以把你的图片放在 style 文件夹中
