geoserver学习1（三）图层样式sld标签

https://docs.geoserver.org/latest/en/user/styling/sld/cookbook/points.html#example-points-layer

给图层的样式添加文字标签

该标签在设定<TextSymbolizer>上 ，确定要在标签中显示的文本，在这种情况下，<ogc:PropertyName>num</ogc:PropertyName>是shp文件中的属性列的值。

<Fill> <CssParameter name=”fill”>#000000</CssParameter> </Fill>设置文本颜色。有关标签的所有其他详细信息均设置为渲染器默认值，这里是Times New Roman字体，黑色字体和10像素的字体大小。标签的左下方与该点的中心对齐。
