Implement Custom Logger with slf4j

Question

I want to implement a Custom logger which logs all log entries to a Database. Currently my app logs this way (slf4j and log4j binding):

private static final Logger logger = LoggerFactory.getLogger( MyClass.class );

I'm not sure how to proceed. My Idea is to implement a Custom Logging binding through implementing the org.slf4j.Logger Interface

What would be the next steps? My target is to not change the current code

Links I considered:

Answer 1

it should be fairly easy. you'll need to implement your own Logger and LoggerFactory. you will not have to change existing code at all.

after doing that you'll need to implement StaticLoggerBinder to return your logger factory and class name. if you download the slf4j zip file then you get the source for all the implementations too, just have a look at the StaticLoggerBinder in slf4j-log4j for an example.

have a look at this link for details : http://www.slf4j.org/faq.html#slf4j_compatible
