禁用Java zookeeper api中的日志消息

Question

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

12:31:39.142 [localhost-startStop-1-SendThread(localhost:2182)] DEBUG org.apache.zookeeper.ClientCnxn - Got ping response for sessionid: 0x14f7213a94000be after 0ms

12:31:39.142 [localhost-startStop-1-SendThread(localhost:2182)] DEBUG org.apache.zookeeper.ClientCnxn - Got ping response for sessionid: 0x14f7213a94000bd after 0ms

12:31:39.183 [localhost-startStop-1-SendThread(localhost:2182)] DEBUG org.apache.zookeeper.ClientCnxn - Got ping response for sessionid: 0x14f7213a94000bf after 0ms

12:31:39.183 [localhost-startStop-1-SendThread(localhost:2182)] DEBUG org.apache.zookeeper.ClientCnxn - Got ping response for sessionid: 0x14f7213a94000c0 after 0ms

12:31:39.256 [localhost-startStop-1-SendThread(localhost:2182)] DEBUG org.apache.zookeeper.ClientCnxn - Got ping response for sessionid: 0x14f7213a94000c1 after 0ms

我更改了日志4J2。也使用root level=“OFF”的xml

如何关闭此日志记录

Answer 1

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。我会增加日志级别，以警告日志4j中的错误。属性文件（conf director）。有关更完整的解释，请参见此处：

Why does zookeeper not use my log4j.properties file log directory

Answer 2

您可以在log4j2.xml中添加另一个记录器来更改zookeeper的日志级别。假设已经定义了名为file的Appender，可以添加Logger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>
