java.lang.IllegalStateException: Async support must be enabled on a servlet and for all filters invo
Spring MVC 项目在使用 DeferredResult 实现异步接口时出现错误。
完整错误信息如下：
十一月 03, 2017 8:59:53 上午 org.apache.catalina.core.StandardWrapperValve invoke
严重: Servlet.service() for servlet [SpringMVC] in context with path [/smarthome] threw exception [Request processing failed; nested exception is java.lang.IllegalStateException: Async support must be enabled on a servlet and for all filters involved in async request processing. This is done in Java code using the Servlet API or by adding "true " to servlet and filter declarations in web.xml.] with root cause

} else {
req.setAttribute(ConstantDict.SESSION_USER, p);
// 继续访问其他资源
chain.doFilter(req, res); //这里为发生错误的语句
}
}这个问题怎么解决呢？
其实错误提示中已经写的很清楚了：
java.lang.IllegalStateException: Async support must be enabled on a servlet and for all filters involved in async request processing. This is done in Java code using the Servlet API or by adding "
需要在 web.xml 文件中的 filter 和 servlet 定义中添加："
以下是完整的 web.xml，请参考"
