Description
Logger Not Declared Static Final
Loggers should be declared to be static and final.
It is good programming practice to share a single logger object between all of the instances of a particular class and to use the same logger for the duration of the program.
The following statement errantly declares a non-static logger.
private final Logger logger = Logger.getLogger(MyClass.class);
Poor Logging Practice: Multiple Loggers
It is a poor logging practice to use multiple loggers rather than logging levels in a single class.
Good logging practice dictates the use of a single logger that supports different logging levels for each class.
The following code errantly declares multiple loggers.
public class MyClass {
private final static Logger good =
Logger.getLogger(MyClass.class);
private final static Logger bad =
Logger.getLogger(MyClass.class);
private final static Logger ugly =
Logger.getLogger(MyClass.class);
...
}
