Spring Retry @Recover passing parameters

Question

I couldn't find any info about a possibility of action I need. I am using @Retryable annotation with @Recover handler method. Smth like this:

    @Retryable(value = {Exception.class}, maxAttempts = 5, backoff = @Backoff(delay = 10000))
    public void update(Integer id)
    {
        execute(id);
    }

    @Recover
    public void recover(Exception ex)
    {
        logger.error("Error when updating object with id {}", id);
    }

The problem is that I don't know, how to pass my parameter "id" to recover() method. Any ideas? Thanks in advance.

According to the Spring Retry documentation, just align the parameters between the @Retryable and the @Recover methods :

The arguments for the recovery method can optionally include the exception that was thrown, and also optionally the arguments passed to the orginal retryable method (or a partial list of them as long as none are omitted). Example:

@Service
class Service {
    @Retryable(RemoteAccessException.class)
    public void service(String str1, String str2) {
        // ... do something
    }
    @Recover
    public void recover(RemoteAccessException e, String str1, String str2) {
       // ... error handling making use of original args if required
    }
}

So you could write :

@Retryable(value = {Exception.class}, maxAttempts = 5, backoff = @Backoff(delay = 10000))
public void update(Integer id) {
    execute(id);
}

@Recover
public void recover(Exception ex, Integer id){
    logger.error("Error when updating object with id {}", id);
}
