Write AMP log into a separate logger file?

[sunquanbin]

Hi,

I'm currently using the "org.apache.log4j.Logger" to write logs in the Java controllers of web scripts for the AMP I'm working on.

I have noticed that the logs are written in "Alfresco.log" file. It is possible that I can write logs of an AMP into a separate file, e.g. my_amp.log?

Regards,

Sun

Of course you can,it is the same with configuring separate log file for different categories in log4j.
Just create a log4j configure file for your module,
in your log4j file configure a new file appender,for example

log4j.appender.moduleLog=org.apache.log4j.FileAppender
log4j.appender.moduleLog.File=yourmodule.log
log4j.appender.moduleLog.layout=org.apache.log4j.PatternLayout
log4j.appender.moduleLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n
‍‍‍‍‍‍

then configure you module class to use the appender.

log4j.logger.com.yourcompany.your.module=info,moduleLog
‍‍‍

Hi kaynezhang,

Thanks for the reply, but I cannot get it to work. In the built amp file, I have two two log4j.properties files in the following path:

1: my_module_id.amp\log4j.properties
2: my_module_id.amp\config\alfresco\module\my_module_id\
‍‍‍‍

In the first file:

log4j.logger.my_module_id=info,moduleLog‍‍

In the second file:

log4j.appender.moduleLog=org.apache.log4j.FileAppender

log4j.appender.moduleLog.File=my_module_id.log

log4j.appender.moduleLog.layout=org.apache.log4j.PatternLayout

log4j.appender.moduleLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n
‍‍‍‍‍‍‍‍‍

In the java code:

logger.error("test error msg");‍

The error still was logged in alfresco.log file.

Can you help?

Many thanks,

Sun

1.First you must place your log4j.properties file in correct location,you should place and name it under following pattern

classpath*:alfresco/module/*/log4j.properties
‍‍‍

2.Second why did you separate your module log4j configuration into two files ? following is a sample module log4j config file,you can copy and past it into your amp log4j.properties .it should work.

log4j.rootLogger=TRACE, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.appender.moduleLog=org.apache.log4j.FileAppender
log4j.appender.moduleLog.File=my_module_id.log
log4j.appender.moduleLog.layout=org.apache.log4j.PatternLayout
log4j.appender.moduleLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.logger.com.yourcompany.your.custom.demo=info,moduleLog
‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thanks very much. I have used the second section of your settings, as the first section makes the programming not running properly.

log4j.appender.moduleLog=org.apache.log4j.FileAppender

log4j.appender.moduleLog.File=my_module_id.log

log4j.appender.moduleLog.layout=org.apache.log4j.PatternLayout

log4j.appender.moduleLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n 

log4j.logger.com.yourcompany.your.custom.demo=info,moduleLog

I now only use 1 file in the path you specified. It works now.

The reason to have 2 files it's because I'm using the Maven alfresco SDK and it comes with 2 files.
