Get failure exception in @HystrixCommand fallback method

Question

Is there a way to get the reason a HystrixCommand failed when using the @HystrixCommand annotation within a Spring Boot application? It looks like

Answer 1

I haven't found a way to get the exception with Annotations either, but creating my own Command worked for me like so:

public static class DemoCommand extends HystrixCommand {

    protected DemoCommand() {
        super(HystrixCommandGroupKey.Factory.asKey("Demo"));
    }

    @Override
    protected String run() throws Exception {
        throw new RuntimeException("failed!");
    }

    @Override
    protected String getFallback() {
        System.out.println("Events (so far) in Fallback: " + getExecutionEvents());
        return getFailedExecutionException().getMessage();
    }

}

Hopefully this helps someone else as well.
