jsp页面编译不通过，直接看jsp页面吧，jsp中的request没有getDispatcherType这个方法，直接把jsp中<%request.getDispatcherType();
request.getDispatcherType();%>类似这段代码删除掉就行了。
request.getDispatcherType();%>类似这段代码删除掉就行了。

亲，就是说你的代码出问题了，编译你的jsp为servlet的时候出错了，错误原因是：
getDispatcherType() is undefined for the type HttpServletRequest
这句话就是说 HttpServletRequest中是没有getDispatcherType() 这个方法的，也就是说request.getDispatcherType();这句java代码有问题！
你可以给我讲讲你想要实现的功能，可以帮您看看！
有什么问题你都可以追问我，没问题，望采纳，谢谢

maven tomcat8中建了一个jsp 然后打包运行 访问一个随便的jsp就出错了
追答
从表面报错的来看就是HttpServletRequest没有你的这个方法，我查了下，你的这个方法在这个类中javax.servlet.ServletRequestWrapper。
