我在一个项目上使用JAK已有一年多了。我用它来创建KML，然后将其编组为普通的KML（而不是KMZ）。我创建了一个单独的实用程序类，该实用程序类使用Java
SE“
Zip”类手动创建KMZ。它工作正常。KMZ只不过是一个.zip存档，其中仅包含一个.kml文件和0个或多个资源文件（例如图像等）。唯一的区别是，在输出文件时，将其命名为.kmz而不是.zip。在KML文档
<Style>定义中，请使用与KML文档本身有关的路径来引用您的资源文件。KML文件被认为位于KMZ归档文件的“根目录”中。如果您的资源文件也位于KMZ（.zip）的根目录中，则您不需要路径，只需文件名。
编辑： 我实际上忘记Kml
了在压缩文件之前删除了将JAK
对象编组到文件的中间步骤。我下面的实用程序方法会将Kml
对象直接封送到ZipOutputStream
。
这是我创建的实用程序类，用于执行我所描述的事情。我将其发布在这里，希望其他人发布仅使用JAK的替代解决方案，以便将来我可以停用此代码。目前，这将为您完成工作。
注意：如果不使用slf4j，Apache Commons Lang或Commons I /
O，则只需对代码进行一些调整即可用您自己的代码删除/替换这些位。 显然，此代码需要JAK库。
