我在src文件夹下添加了log4j.properties:

I added log4j.properties under src folder:

# 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.

推荐答案

我再次检查了包含的库，发现包含了 LogBack.我认为 JVM 加载 logback 而不是 log4j.一旦我提供了 logback.xml，问题就解决了.

I have checked again my included library, and I found out that LogBack was included. I think JVM load logback instead of log4j. Once I supply logback.xml, the problem is solved.
