com.ali.druid.support.http.StatViewServlet cannot be cast to class

Caused by: java.lang.ClassCastException: class com.alibaba.druid.support.http.StatViewServlet cannot be cast to class jakarta.servlet.Servlet (com.alibaba.druid.support.http.StatViewServlet and jakarta.servlet.Servlet are in unnamed module of loader 'app')

报错意思，com.alibaba.druid.support.http.StatViewServlet 无法转换为 jakarta.servlet.Servlet ，
你用的Servlet api 是 Jakarta 的吧， 换成 javaee-api 或者 servelt-api
