Spring Global Exception Handler - Not MVC

Question

Does regular Spring (Boot) have a way to do global exception handling, or at least catch any uncaught exceptions (such as RuntimeException that may happen randomly)?

I've googled around, but everything I've found talked about the @ControllerAdvice @ExceptionHandler for controllers. Nothing about just a general global exception handler.

I basically just want to make sure that if some exception happens that I'm not already catching, that I log it so I know about it.

Answer 1

Add your own via AOP, something like this will work:

@Aspect
@Component
public class ExceptionHandler {

    @AfterThrowing(pointcut = "within(*.*)", throwing = "t")
    public void log(Throwable t) {
        t.printStackTrace();
    }
}

Look at the cheat sheet to help with the pointcut.

Answer 2

I think spring does not provide an out of the box solution for this.

A possibility to achieve this is using AOP with annotations (you may find an example here: Where can I catch non rest controller exceptions in spring?). With this approach, you can define a global pointcut for all the methods annotated with a pre-defined annotation. The good part of this approach is to have all the error handling logic in one place.
