大家好，欢迎来到IT知识分享网。
1.下载并安装GeoServer
2.启动服务
默认账号是admin,密码geoserver
3.使用QGIS为样例图层配色(以面积大小分类配色)
导出样式文件
4.添加样式至GeoServer样式库
5.新建工作空间
设置权限，方便服务调用
6.添加图层数据，因为样例是.shp格式，所以我选择Shapefile - ESRI(tm) Shapefiles (*.shp)
7.选择工作区间，设置图层数据的路径
8.发布图层
设置样式，点击发布栏
9.预览图层
如果点击Openlayer出现不能预览，变成下载WMS文件，可以下载用记事本打开查看问题原因！！！
中文乱码了，￣□￣｜｜ 待解决…
**2022-7-28 => **GeoServer发布服务，中文标注乱码
打工人使劲搬砖~~~ 终于解决了，文章的截图就懒得修改了O(∩_∩)O~
10.QGIS加载服务
复制WMS服务链接
打开QGIS,右键WMS/WMTS服务，新建连接
11.ArcGIS for JS 调用服务

出现跨域访问问题
windwos安装包2.21.0版本Geoserver解决跨域（亲测，可行）
打开geoserver\webapps\geoserver\WEB-INF下的web.xml文件。去掉下面代码的注释，在bin文件夹下startup.bat重启即可。
