在Java中的ZIP文件中获取目录的内容

Question

I have some default configuration files inside my application jar that I would like to save to the file system if they don't already exist. I would like it to keep the directory structure too. Example:

Jar file
-configs/
    -main-config.cfg
    -another-file.txt
    -stuff/
        -another-file.cfg
-com/
-META-INF/

I would like the contents of configs/ to be mirrored to the file system, including the subfolder.

使用JarFile.entries可以获取Jar文件中所有条目的枚举。
