GeoWebCache 关于GeoWebCache的部署说明(1)
总结了网络的各种资料终于成功部署,并加载arcgis wms服务(当然tilecache部署失败了,有时间再试试)
主要修改2个地方(包用的1.5的,目前最新的1.7的部署失败)
1.将geowebcache-1.5.3-war 解压的tomcat webapp下
修改web.xml内容
<context-param>
<param-name>GEOWEBCACHE_CACHE_DIR</param-name>
<param-value>D:/geowebcache/data</param-value>
</context-param> 在<web-app>根目录下添加上面代码
param-value:指定图片缓存位置
2.启动tomcat
在D:/geowebcache/data下会生成如下文件
2.修改geowebcache.xml添加自己的图层服务,进行切图
修改后的内容

当然具体的参数需要自己去查找与自己图层一致的参数(可以参考部署说明(2))
3.我是直接预览的
4.可以查看1中生成的文件夹内容,就是缓存的切片
5.附上openlayer调用显示代码
