web.xml过滤器如何工作？你有两个过滤器映射到所有页面（/ *）并指定顺序吗？ [英] How do web.xml filters work? Can you have two filters map to all pages (/*) and specify the order?

问题描述

我想使用Spring Security，它说要将过滤器映射到/ ***。但我已经有一个映射到/ *的过滤器，它是Tuckee URLRewrite过滤器。

I want to use Spring Security, and it says to map the filter to /***. But I already have a filter mapped to /*, which is the Tuckee URLRewrite filter.

是否可以将两个过滤器映射到同一个东西，并且还有一个指定过滤器被调用的顺序的方法？

Is it possible to map two filters to the same thing, and also is there a way to specify the order that the filters get called?

推荐答案

是的，你可以：

servlet 2.5 xsd ：

调用过滤器的顺序是与servlet的请求URI匹配的过滤器映射声明出现在过滤器列表中的顺序 - 映射元素

The order in which filters are invoked is the order in which filter-mapping declarations that match a request URI for a servlet appear in the list of filter-mapping elements

即它取决于 web.xml中< filter-mapping> 元素的顺序

i.e. it depends on the order of your <filter-mapping> elements in the web.xml
