Use of SimpleLayout in Log4j
In the previous example we have studied that there are
many Layout classes for displaying logging output in the desired format. In this
section we are going to describe you one of them, SimpleLayout, the
simplest of all.
Example of SimpleLayout log message is as
follows:
"Debug - and debug log message".
In our example of SimpleLayoutExample we are
using FileAppender to append the output log message to a
log file "SimpleLog.log". First we have created an object of Logger
class by calling static method getLogger(). After creating FileAppender
object we have added this appneder to our logger with the addAppender() method.
Here is the example code of SimpleLayoutExample class:
import org.apache.log4j.*;
public class SimpleLayoutExample{
static Logger logger =
Logger.getLogger("SimpleLayoutExample.class");
public static void main
(String[] args) {
try
{
FileAppender fileappender =
new FileAppender(new SimpleLayout(),"SimpleLog.log");
logger.addAppender(fileappender);
logger.info("First Log");
logger.info("Second Log");
logger.info("Third Log");
logger.info("Fourth Log");
logger.info("See your SimpleLog.log");
logger.info("Exiting from the Main method ");
}catch(Exception e){
e.printStackTrace();
}
}
}

After creating and executing this
SimpleLayoutExample class file you will get SimpleLog.log file with
the following Log event messages.
