Primefaces 当前链的筛选器或servlet不支持推送servlet中的异步操作

当我们试图在大气依赖的帮助下实现USEServlet时，我们遇到了一个问题 我们可以使用当前配置在本地运行，但当我的应用程序部署到aws时，推送servlet无法工作。 aws中的日志是 我的Aws服务器配置为Java 8和Tomcat 8版本2.1.3

64位Amazon Linux 2016.03 v2.1.3运行Tomcat 8 Java 8 2016.03.2 Java 1.8.0_91 Tomcat 8.0.35 Apache 2.2.31

web.xml中的推送servlet配置为

<servlet>
    <servlet-name>Push Servlet</servlet-name>
    <servlet-class>org.primefaces.push.PushServlet</servlet-class>
   <init-param>
        <param-name>org.atmosphere.cpr.broadcasterCacheClass</param-name>

</servlet>

  <servlet-mapping>
    <servlet-name>Push Servlet</servlet-name>
    <url-pattern>/primepush/*</url-pattern>
</servlet-mapping>

我被修好了。这是我错了的原因

当我检查所有的过滤器时，我发现了另一个过滤器元素true，当push servlet调用时，该过滤器工作。

更改为false
