禁用Java zookeeper api中的日志消息

我反复收到这些日志消息

12:31:39.085 [localhost-startStop-1-SendThread(localhost:2182)] DEBUG org.apache.zookeeper.ClientCnxn - Got ping response for sessionid: 0x14f7213a94000bc after 0ms

我还使用root-level=“OFF”更改了log4j2.xml

如何关闭此日志记录？

您的日志级别是DEBUG，这确实非常冗长，不适合在生产系统中使用。我会提高日志级别，以警告log4j.properties文件（confdirector）中的错误。有关更完整的说明，请参见此处：

您可以在

log4j2.xml

中添加另一个记录器来更改zookeeper的日志级别。假设您已经定义了名为

file

的Appender，您可以添加

记录器

部分，如下所示

<Appenders>
  <RollingFile name="file" ...
   ...
  </RollingFile>
</Appenders>
<Loggers>
  ...
  <Logger name="org.apache.zookeeper" level="warn" additivity="false">
    <AppenderRef ref="file"/>
  </Logger>
  ...
</Loggers>
