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          


        

Answer 1

You do not have to write your own logging implementation, how about switching the logging framework to logback? Loback supports logging to database natively. As you use the SLF4J API both times your code won't change.

Take a look at the ch.qos.logback.classic.db.DBAppender. If the default table layout does not fit your needs, you can implement ch.qos.logback.classic.db.names.DBNameResolver to customzie the table and coloum names.

Answer 2

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
