springMVC项目异步处理请求的错误Async support must be enabled on a servlet and for all filters involved in async

从github上down下来一个项目，springMVC-chat。作者全是用的注解，也就是零配置。

这可苦了我，经过千辛万苦，最终集成到现在的项目中有一点样子了，结果报出来下面的错误。红色部分。解决方法为，在web.xml中也就是springMVC的总配置文件中加上一句话：

<async-supported>true</async-supported>

这句话的位置一定要放正确，否则，一切都是徒劳。至于配置spring异步支持（其实是配置servlet异步支持）的放置位置见下图。
