Hi，大家好，我是编程小6，很荣幸遇见你，我把这些年在开发过程中遇到的问题或想法写出来，今天说一说javax.servlet.FilterChain[通俗易懂],希望能够帮助你!!!。
javax.servlet

Interface FilterChain

public interface FilterChain

A FilterChain is an object provided by the servlet container to the developer giving a view into the invocation chain of a filtered request for a resource. Filters use the FilterChain to invoke the next filter in the chain, or if the calling filter is the last filter in the chain, to invoke the resource at the end of the chain. FilterChain是一个由servlet容器提供给开发人员的对象，给出某资源的过滤请求的调用链视图。 Filter使用FilterChain调用链中的下一个过滤器，如果调用过滤器是链中的最后一个过滤器， 调用链尾部的资源。

Since:

Servlet 2.3
