Question

Rational

I would like to have more detailed logging debugging/logging output on a few superclasses, so the subclass name will not actually be effecting real-time performance nor application logic. I’m also of the opinion that it is fairly bad design to do this normally, however I really do want this info to be logged during development runs.

Question

Suppose I have a simple class structure as below, how do I pull the name of the subclass into the superclass without having to explicitly pass a reference?

public abstract AbstractClass {     private Logger logger = LoggerFactory.getLogger(getClass());      public AbstractClass() {}      public void execute(ContextObject context) {         if (logger.debuggingEnabled()) {             String invokingClassName = ''; // <-- how do I get this?             logger.debug('Executing {}', invokingClassName);         }         // shared application logic is here...     } }  public MyClass extends AbstractClass {     public MyClass() {}      @Override     public void execute(ContextObject context) {         super.execute(context);         // application logic...     } } 

I have worked with parsing stack traces before and I suspect that is the route I will have to go if I want this information. Does anyone know of a library that will do this for me or a good code snippet?

Answer 1

Doesn’t this.getClass().getName() do the trick? Namely:

public void execute(ContextObject context) {     if (logger.debuggingEnabled()) {         String invokingClassName = ''; // <-- how do I get this?         logger.debug('Executing {}', this.getClass().getName());     }     // shared application logic is here... }
