我正在使用一个Spring-MVC应用程序，我正在使用Cometd进行聊天。为此，我必须在tomcat中使用async-mode。经过一些研究，我发现我可以为异步模式配置tomcats NIO连接器。
即使这样做，我也会遇到同样的错误。我发布了调试日志，web.xml和服务器配置。请告诉我有什么问题。
调试日志：

Server.xml :(我暂时删除了8080上的重定向）
<Connector connectionTimeout="20000" maxThreads="1000" port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol"/>
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" SSLEnabled="true" maxThreads="150"
scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" maxHttpHeaderSize="8192" connectionTimeout="20000"
keystoreFile="/home/username/.keystore" keystorePass="password" />
Web.xml :( Cometd相关部分）
<servlet>
<servlet-name>cometd</servlet-name>
<servlet-class>org.cometd.server.CometDServlet</servlet-class>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>cometd</servlet-name>
<url-pattern>/cometd/*</url-pattern>
</servlet-mapping>
有什么问题，请告诉我。我还尝试在POM.xml中添加带有提供范围的apache.tomcat.util，但这没有帮助。非常感谢。 ： - ）
答案 0 :(得分：0)
您使用的是会话管理器（Redis，Terracota ......）吗？ 如果是，则必须在Tomcat的context.xml文件中定义会话Valve。
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
尝试添加asyncSupported =＆＃34; true＆＃34;属性为此配置：
<Valve asyncSupported="true" className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
