您好我想根据appengine上的KML文件创建一个shapefile（.shp .shx .prj .dbf）。我的项目是关于java。
我尝试使用geotools，并且能够在Appengine上创建.shp .shx .prj（在地理工具上进行一些更改以保存在Google Cloud上）但是无法使用它创建.dbf。 Geotools依赖于AWT来创建dbf，而Appengine则限制AWT。
对此有什么消息？我甚至开始考虑调用python模块或其他东西（从未做过这样的事情）。甚至可以从kml创建一个dbf。

当我呼叫ShapefileDatastore.createSchema()时，我必须传递SimpleFeatureType作为参数。
当我尝试创建SimpleFeatureType或甚至使用BasicFeatureTypes.POLYGON时，它给了我错误：

我将RenderingHints替换为非awt RenderingHints，并且他们又出现了另一个错误：

似乎使用了很多AWT的工厂方法（在这种情况下图形不是问题，只是使用AWT的东西）。
我也替换了它并得到了：

我还不知道这个javax.imageio.spi.ServiceRegistry（我已经取代了我找到的所有东西）来自哪里，并且我认为我扭曲了很多这似乎不是那样......
