Throwing an exception from @ExceptionHandler to get caught by another handler

Question

I have a @ControllerAdvice class to handle exceptions from my SpringMVC controllers. I would like to catch an exception of a known type (RuntimeException) in an @ExceptionHandler method then throw the e.getCause() exception and have this exception caught by the same @ControllerAdvice class.

Sample code:

@ControllerAdvice
public class ExceptionHandlingAdvice
{
    @ExceptionHandler( RuntimeException.class )
    private void handleRuntimeException( final RuntimeException e, final HttpServletResponse response ) throws Throwable
    {
        throw e.getCause(); // Can be of many types
    }

    // I want any Exception1 exception thrown by the above handler to be caught in this handler
    @ExceptionHandler( Exception1.class )
    private void handleAnException( final Exception1 e, final HttpServletResponse response ) throws Throwable
    {
        // handle exception
    }
}

Is this possible?

Answer 1

You can check if that RuntimeException is instance of Exception1.class and call the method directly:

 private void handleRuntimeException( final RuntimeException e, final HttpServletResponse response ) throws Throwable
{
    if (e instanceof Exception1) handleAnException(e,response);
    else throw e.getCause(); // Can be of many types
}
