How to stop logging in jetty application

use*_*565 2 java jetty logback slf4j embedded-jetty

I am using jetty to implement websocket client. This is producing a lot of noise in log file in start up of application and when failed reconnect websocket. Actually in case of websocket connection failure i am retrying after a minute so after every minute it it producing this kind of log:

Can someone give me hint how i can reduce this unused logging as it creating a lot of disk space when program is running. I am wondering is it possible to enable disable this jetty log from application or by adding some parameter in logback.xml file

如果您只想完全禁用来自 jetty 的日志，您可以添加以下行：

<configuration>
...
    <logger name="org.eclipse.jetty" level="OFF" />
....
</configuration>

ERROR如果您只想要错误级别消息，也可以将其更改为。

将<root level="DEBUG">增加到更高级别将影响整个应用程序以及来自码头的日志。
