How to disable log4j logging in Http Client 4.1 to

问题:

Here is my log4j configuration for a HTTP client:

log4j.appender.HTTPCLIENT_APPDR=com.xxx.log.FileAppender
log4j.appender.HTTPCLIENT_APPDR.File=${user.dir}/log/access.log
log4j.appender.HTTPCLIENT_APPDR.layout=org.apache.log4j.PatternLayout
log4j.appender.HTTPCLIENT_APPDR_APPDR.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss SSS}ms %-5p [%t] - %m%n
log4j.appender.HTTPCLIENT_APPDR.MaxFileSize=20000KB
log4j.appender.HTTPCLIENT_APPDR.MaxBackupIndex=30
log4j.logger.org.apache.http=DEBUG,HTTPCLIENT_APPDR

I would like it to turn off the httpclient logging from the CODE depending on the environment I am in (I know how to disable it from the log4j.properties).

I tried inserting these lines:

+    System.setProperty("log4j.logger.org.apache.http", "ERROR"); 

or

+    Logger.getLogger("log4j.logger.org.apache.http").setLevel(Level.off)

in the start of my application but it does not work.

1. Can I access the log4j properties from the System class?
2. When I look at the Logger.getLogger("log4j.logger.org.apache.http") the level is null? Should it not be DEBUG?

What worked finally,

Logger.getLogger("org.apache.http").setLevel(org.apache.log4j.Level.OFF);

I was not using the right key.

Regards,

If you have a log4j.properties file, add this line

log4j.logger.org.apache.http=WARN

This is only tested in Apache HttpClient 4
