AFAIK你不能在没有太多麻烦的情况下修改jar内的资源（基本上它是一个zip，因此它应该是可能的，但可能有由JVM等文件锁定。）。

AFAIK you can't modify resources inside a jar without much hassle (basically it is a zip and thus it should be possible, but there might be file locks by the JVM etc.).

此外，你不能把一个jar放到另一个jar中。但是，如果需要，可以解压缩驱动程序jar并将内容包含在jar中。 Maven程序集插件的目标是这样做： jar-with-dependencies 。

Additionally, you can't put one jar into another. However, you could unpackage the driver jar and include the contents in your jar, if you want that. The Maven assembly plugin has a goal that does this: jar-with-dependencies.
