log problem

冰火共舞

In my hibernate project,
Exception: log4j: WARN No appenders could be found for logger (org.apache.catalina.startup.Embedded).
log4j: WARN Please initialize the log4j system properly.
log4j: WARN No appenders could be found for logger (org.apache.commons.beanutils.ConvertUtils).
log4j: WARN Please initialize the log4j system properly.
log4j: WARN No appenders could be found for logger (org.apache.commons.digester.Digester).
log4j: WARN Please initialize the log4j system properly.

What causes it? How to deal with it? Thank you

It may be that the configuration file is missing.

Cannot find the configuration file, it may be the wrong path

Which configuration file? The project can run, but it is these warnings
log4j: WARN No appenders could be found for logger (org.apache.catalina.startup.Embedded).
log4j: WARN Please initialize the log4j system properly.
log4j: WARN No appenders could be found for logger (org.apache.commons.beanutils.ConvertUtils).
log4j: WARN Please initialize the log4j system properly.
log4j: WARN No appenders could be found for logger (org.apache.commons.digester.Digester).
log4j: WARN Please initialize the log4j system properly.

Please be specific, I am a novice

Because you use tomcat struts, and the printed classes are all used in tomcat / struts, they all use the commons-logging lib, commons-logging find log4j in the classpath, use log4j But your log4j didn't configure corresponding appenders for them, so it will alarm. Can be ignored

It should be a path problem

I probably understand what it means. Where can I configure log4j appender?
