Tomcat：NIOConnector抛出异常

标签： java spring tomcat asynchronous nonblocking

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。 ： - ）

1 个答案:

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" />
