Spring WebFlow项目。 我无法从打印调试语句中停止log4j

Question

I am working on a Spring WebFlow Project. I can't stop log4j from printing debug statements. can someone please tell me how to get it to stop putting debug statments on the console and log.

I see this warn as my server starts:

log4j:WARN Continuable parsing error 42 and column 11
log4j:WARN The content of element type "logger" must match "(level?,appender-ref*)".

Below is my log4j.xml file:

Answer 1

This is just a log4j issue. It appears that <priority> is not a valid sub-element of the logger element <root> . Rather, you should have <level> instead.
