终于找到了解决方案。
我必须从官方来源下载SIGAR。

Finally found the solution. I had to download SIGAR from the official source.

然后我必须复制/粘贴整个lib文件夹（包含所有 .so 和 .dll 和诸如此类的东西）进入项目的main / src / webapp文件夹，Spring用它来存储所需的应用程序（或者我假设）。

Then I had to copy/paste the entire "lib" folder (with all the .so and .dll and whatnot) into the folder "main/src/webapp" of the project, which is used by Spring to store needed apps (or so I assume).

然后在运行 mvn install 之后，检查target文件夹并运行新生成的 .war 文件，一切都按预期运行。

Then after running mvn install, checking the "target" folder and running the newly generated .war file, everything runs as expected.
