 A servlet filter that allows for advanced dispatching.

servlet过滤器：用来做高级分发。

简介：This fiter allows for a single mapping from web.xml for all requests to the spring dispatcher.  It creates a wrapper around the servlet request object that "fakes" the serveltPath property to make it look like the mapping was created in web.xml when in actuality it was created in spring. @author Justin Deoliveira, OpenGeo

简介：该过滤器用来为向spring分发器的连接请求创建一个来自web.xml的单个映射。它为servlet请求创建一个wrapper，伪造servletPath属性，从而使得它看上去像是在web.xml中创建的映射，但是它实际上是在spring中创建的。作者：Justin Deoliveira

public class AdvancedDispatchFilter implements Filter {

}

目的: 改变请求参数的值,满足项目需求(如:过滤请求中 lang != zh 的请求)
