我刚刚下载了 Pet Clinic 示例（我想将其重写为 Spring Portlet MVC）并且在每个包中都有package-info.java类。除了包声明，文件是空的，那么这有什么用？我可以在 Spring Portlet MVC 中安全地省略它吗？

You can safely delete these but normally from my experience you'd just put a description of what the package is for in a comment in this file.
You can find more info on the Oracle website here
