log4j2配置文件未记录到控制台/文件

Question

I have the following log4j2.xml config that I am using. I have 2 issues :-

1. When my application runs up, I have nothing logged to either the console or to mylog.log file by either of apache or springframework or hibernate classes.

2. Classes within the package "com.foo.bar", I am able change the log LEVEL via "level" attribute but the messages are only logged to mylog.log file but nothing to the console

Any suggestions to above would be appreciated ?

thank you Pete

Answer 1

Please try replacing

<Root level="all">

With

<Root level="trace">

Answer 2

It sounds like you have a misconfigured log.

Can you debug remotely and where you find use the logger to log something place a breakpoint. Inspect the logger and then you will find a location of where its picking up the log file from.

Also try providing a VM argument for log4j configuration (-Dlog4j.configuration)on start-up of your application.
