这个是由于Java 9及以上版本引入了模块化系统，加强了对Java核心库的访问控制，而某些第三方库使用了Java核心库的非公开API，就会导致这种警告信息的出现。可以通过添加--add-opens命令行参数来解决这个问题，例如：--add-opens java.base/java.lang=ALL-UNNAMED。这样可以打开对java.base/java.lang包的访问，但这并不是推荐的做法，因为这可能会导致安全问题。更好的解决方案是更新使用的第三方库，或者等待它们更新以适应新的Java版本。

WARNING: An illegal reflective access operation has occurred

This warning message indicates that the Java code is using a feature that is not officially supported or recommended by the Java development team. This can be caused by using an outdated or deprecated API, or by using a third-party library that is not compliant with the latest Java standards.

While this warning message does not necessarily mean that the code is broken or will not function, it is a good idea to investigate why the code is generating this warning and see if there is a more compliant way to achieve the same functionality. Ignoring this warning could result in compatibility issues or security vulnerabilities in the future.

这是一个由于 Java 程序运行时反射操作导致的错误。反射是 Java 程序中用于在运行时访问、操作类、接口、字段和方法的机制，但是反射操作也可能会导致安全问题。请检查程序代码是否正确使用了反射操作。
