如何使LogbackValve異步支持？

Question

我在我的web應用程序中使用logback-access。

但是，當我在server.xml中使用<Valve className="ch.qos.logback.access.tomcat.LogbackValve"/>時，使用request.startAsync（）的我的servlet將失敗。

這是因爲ch.qos.logback.access.tomcat.LogbackValve不asyncSupported。 那麼我怎樣才能使它asyncSupported？

Answer 1

您只需要在server.xml中設置配置閥門的asyncSupported="true"屬性。

<Valve className="ch.qos.logback.access.tomcat.LogbackValve" asyncSupported="true"/>
