如何解决tomcat10仲javax和jakarta的冲突问题

引用 **org.apache.tomcat.util.http.fileupload.servlet.*** 或 **org.apache.commons.fileupload.servlet.*** 的时候，java文件最开头标出异常：**The type jakarta.servlet.http.HttpServletRequest cannot be resolved. It is indirectly referenced from required .class files**

上网查了一下感觉像是javax的jakarta冲突问题，网上大多数解决方法就是放弃tomcat10用回tomcat9，难道就没有其他更好的解决方法了吗？

环境是 win10 + eclipse-2021-06 + java11 + tomcat-10.0.8 。

另外附上源码，希望会有帮助：
