打印下path 就知道了
可以看下源码方法的说明文档。request.getContextPath()获取的是项目的上下文路径，是一个相对路径。是"/"开头的
Returns the portion of the request URI that indicates the context
of the request. The context path always comes first in a request
URI. The path starts with a "/" character but does not end with a "/"
character. For servlets in the default (root) context, this method
returns "". The container does not decode this string.
