Answer 1

解决方法：项目目录下的WEB-INF/lib里面的jar包有冲突，把他们删除就行了。
如果是别的地方移过来的程序 删除里面的 catalina.jar 重新启动 tomcat

Answer 2

端口被占用了，你到tomcat的目录下，有一个server.xml文件，把里面的商品修改下，然后重启下试试

追问

可以肯定 不是端口被占用，我tomcat启动 没有报错 亲。只是访问程序出现那个。

Answer 3

看错误提示:org.apache.jasper.JasperException: java.lang.ClassCastException: org.apache.catalina.util.DefaultAnnotationProcessor cannot be cast to org.apache.AnnotationProcessor

这问题网上有好多成功解决的例子
ava.lang.ClassCastException: org.apache.catalina.util.DefaultAnnotationProcessor cannot be cast to org.apache.AnnotationProcessor

Answer 4

com.huafeng.web.listens.TransmitFilter.doFilter(TransmitFilter.java:51)
，这个应该是你自己的代码，看看这里有什么问题。
