Question

我正在使用Jetty 8和ZooKeeper 3.4.5。当我连接到ZooKeeper时，jetty会继续生成DEBUG级别的消息。怎么抑制它？

我在src文件夹下添加了log4j.properties：

# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, A1

# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender

# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r - [%t] %-5p %c %x - %m%n

log4j.logger.org.apache.zookeeper.ZooKeeper=INFO

仍然没有运气。

Answer 1

我再次检查了我的附带库，我发现LogBack已包含在内。我认为JVM加载logback而不是log4j。一旦我提供logback.xml，问题就解决了。

Answer 2

配置中的这样的东西应该有所帮助：

<logger name="com.apache.zookeeper" level="info">
   <!-- appenders -->
</logger>

在Jetty中嵌入Apache ZooKeeper会生成调试日志消息
