GeoServer简介、下载、配置启动、发布shapefile全流程(图文实践)：

https://blog.csdn.net/BADAO_LIUMANG_QIZHI/article/details/109636080

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。

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

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>
                <Mark>
                  <WellKnownName>square</WellKnownName>
                  <Fill>
                    <CssParameter name="fill">#CCCCCC</CssParameter>
                      <CssParameter   name="fill-opacity">0</CssParameter>
                  </Fill>
                </Mark>
              <Size>6</Size>
            </Graphic>
          </PointSymbolizer>
           <TextSymbolizer>
            <Label>
              <ogc:PropertyName>TEXTSTRING</ogc:PropertyName>
            </Label>
            <Font>
              <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>
            </Font>
            <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

          <MinScaleDenominator>5000</MinScaleDenominator>
          <MaxScaleDenominator>11000</MaxScaleDenominator>

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。
