[GeoServer简介、下载、配置启动、发布shapefile全流程(图文实践)\_霸道流氓气质的博客-CSDN博客\_geoserver简介][GeoServer_shapefile_-CSDN_geoserver]

geoserver在预览图层时，当发大图层时内容不显示。

比如文字text图层，放大到指定层级(比例尺变小时)不显示文字内容。

![f9d64e2d72d94d6491b25f3c2c644410.jpeg][]

这是因为该图层对应的样式文件为自定义的Style，这个样式文件中未设置放大即比例尺缩小范围时对应的样式，

所以文字图层在该比例尺下不显示。

比例尺为预览时左下角的Scale = 1:5000

查看图层对应的样式文件，在图层-发布-WMS Setting-Deafult Style下

![230a26c38a93423d867b39bf94f420c8.jpeg][]

在Styles中找到该样式的具体代码

补充样式中缺失比例尺下的样式设置。

Geoserver的Style的样式中MinScaleDenominator与MaxScaleDenominator分别代表最小比例尺和最大比例尺下

的样式设置。

示例代码如下:

<Rule>
           <MinScaleDenominator>5000</MinScaleDenominator>
           <MaxScaleDenominator>11000</MaxScaleDenominator>
           <Name>rule1</Name>
           <Title>Red Square</Title>
           <Abstract>A 6 pixel square with a red fill and no stroke</Abstract>
             <PointSymbolizer>
               <Graphic>
                 
                   <WellKnownName>square</WellKnownName>
                   <Fill>
                     <CssParameter name="fill">#CCCCCC</CssParameter>
                       <CssParameter   name="fill-opacity">0</CssParameter>
                   </Fill>
                 
               <Size>6</Size>
             </Graphic>
           </PointSymbolizer>
            <TextSymbolizer>
             <Label>
               <ogc:PropertyName>TEXTSTRING</ogc:PropertyName>
             </Label>
             
               <CssParameter name="font-family">宋体</CssParameter>
               <CssParameter name="font-size">18</CssParameter>
               <CssParameter name="font-style">normal</CssParameter>
               <CssParameter name="font-weight">bold</CssParameter>
             
             <LabelPlacement>
               <PointPlacement>
                  <Rotation>             
                  <ogc:PropertyName>TEXT_ANGLE</ogc:PropertyName>
                  </Rotation>
               </PointPlacement>
             </LabelPlacement>
             <Fill>
               <CssParameter name="fill">#CCCCCC</CssParameter>
             </Fill>
              <VendorOption name="spaceAround">15</VendorOption>
              <VendorOption name="group">yes</VendorOption>   
             <VendorOption name="autoWrap">200</VendorOption>
             <VendorOption name="maxDisplacement">5</VendorOption>
           </TextSymbolizer>
         </Rule>

比如这里的

就代表设置比例尺在5000到11000下的样式。

具体样式的属性说明可自行搜索。
