问题描述
我在Web应用程序中使用了logback-access.
I'm using logback-access in my web app.
但是当我在server.xml中使用< Valve className ="ch.qos.logback.access.tomcat.LogbackValve"/> 时.我的servlet使用request.startAsync()将失败.
But when I'm using <Valve className="ch.qos.logback.access.tomcat.LogbackValve"/> in server.xml.My servlet using request.startAsync() will fail.
java.lang.IllegalStateException: Not supported.

这是因为ch.qos.logback.access.tomcat.LogbackValve不支持async.那么如何使它成为asyncSupported?
推荐答案
您只需要设置 asyncSupported ="true" 属性，即可在 server.xml中配置阀门代码>.
You just need to set the asyncSupported="true" attribute where you configure the valve in server.xml.
<Valve className="ch.qos.logback.access.tomcat.LogbackValve" asyncSupported="true"/>
