最近新接触了GeoServer，从零开始的研究也是折磨了好几天，发现GeoServer这块很多大佬分享各种解决方案，也是帮了我大忙，刚好告一个段落了，所以也贡献一下我这几天的研究成果，希望能帮到大家。
目标：使用GeoServer自动化发布NetCDF文件，实现部署在Linux上自动化更新图层
环境：.net6.0，GeoServer 2.21，Linux
先看一下目录结构：
AbstracPublishHandler抽象类中写整体的处理方法，主要是对栅格文件处理的固定流程
附上源码：

DataSourceType中放具体的栅格类型处理方法，目前只用到了NetCDF，NetCDFPublishHandler继承抽象类AbstracPublishHandler直接调用Handling方法即可。

目前只是一个简单跑通的状态，里面其实还有许多需要完善的地方，包括对curl命令执行结果的判断，多个仓库的发布等等，后面再持续更新吧！
