Build a Custom Formatter for a Java.util.logging Logger
For a simple custom logger, you can inherit from the base java.util.logging.Formatter class and override its format method to customize the output. Here's an example:
import java.io.*;
import java.util.*;
import java.util.logging.*;
public class CustomFormatter extends java.util.logging.Formatter
{
public String format(LogRecord log)
{
Date date = new Date(log.getMillis());
String level = log.getLevel().getName();
String logmessage = "{"+level+"}" + "{"+date.toString()+"}\r\n";
logmessage = logmessage + log.getMessage() + "\r\n\r\n";
Throwable thrown = log.getThrown();
if (thrown != null) {
logmessage = logmessage + thrown.toString();
}
return logmessage;
}
}
