How to switch on and off @Recover method in Spring Retry?

Question

I want the @Recover method to be switched on/off based on a flag in the properties file. How to do that?

Actually, I am not using annotations (@Retryable / @Recover), instead, I am using RetryTemplate.

Solution

I am using this following method as a wrapper method to all the recover calls.

private <T> T genericRecover(RetryContext context) {
    if(this.useRecoverMethod) {
        return null;
    }

    throw new RuntimeException(context.getLastThrowable());
}

Here the useRecoverMethod boolean flag is read from the properties file.

public Resource<Camera> myRetyableMethod(Long cameraId) {

    return retryTemplate.execute(context -> anApiCallMethod(param),
                                    context -> genericRecover(context));
}

It's not possible.

But, of course, your @Recover method can re-throw the exception (or not) based on the property.

Looks ok except your recoverer does nothing except ignore the error. Perhaps that's what you want but, generally, people want to do something else, or at least log the problem. – Gary Russell Jan 11 '19 at 14:32
