GWC中添加切片方案的配置

打开缓存文件夹目录下的geowebcache.xml文件。

找到标记<gridSets>，在此条目下创建新的<gridSet>标记。其中必要的子标记是<name>、<srs>、<extent>、<scaleDenominators>、<tileHeight>以及<tileWidth>。其中scaleDenominator标记中的比例尺参数是查看Geoserver中附带的GridSet来帮助制定的。

附上配置成功的EPSG：3857以供参考

    <gridSet>
      <!-- This does not have to be an EPSG code, you can also have multiple gridSet elements per SRS -->
      <name>EPSG:2163</name>

配置成功之后就可以在各个<wmsLayer>标记下使用<girdSubset>标记进行调用和微调了。

例：

    <wmsLayer>
      <name>cite:xzqxz-test-local2</name>
      <mimeFormats>
        <string>image/gif</string>
        <string>image/jpeg</string>
        <string>image/png</string>
        <string>image/png8</string>
      </mimeFormats>
       <gridSubsets>
        <gridSubset>
          <gridSetName>EPSG:4326</gridSetName>
        </gridSubset>
        <gridSubset>
          <gridSetName>EPSG:3857</gridSetName>
          <extent>
            <coords>
              <double>-20037508.34</double>
              <double>-20037508.34</double>

            </coords>
          </extent>
        </gridSubset>
        <gridSubset>
          <gridSetName>EPSG:900913</gridSetName>
        </gridSubset>
      </gridSubsets>
      <wmsUrl>
        <string>http://localhost:8080/K-TopHighGisServer/wms</string>
      </wmsUrl>
