spring-retry中@Recover方法的触发时机：是否在全部重试失败后调用？

Hey there! Let’s break this down plainly so you’ve got no confusion left:

• The @Recover annotated method will only be triggered when two conditions are met:
  1. The associated @Retryable method has used up all its configured retry attempts (e.g., if you set maxAttempts = 3, it will run 3 total times)
  2. The final attempt of the @Retryable method still ends in failure (throws an exception that’s specified in the @Retryable configuration)

To directly answer your second question: It’s not just after all retries are done—it’s only after all retries are done AND the method still fails on that last try. If at any point during the retries the @Retryable method succeeds (doesn’t throw the targeted exception), the @Recover method will never be called.

Here’s a quick code example to make this tangible:

@Service
public class PaymentService {

    // Retry up to 2 more times (total 3 attempts) if a PaymentException is thrown
    @Retryable(value = PaymentException.class, maxAttempts = 3)
    public void processPayment(String orderId) {
        System.out.println("Processing payment for order: " + orderId);
        // Simulate a failing payment
        throw new PaymentException("Payment gateway unavailable");
    }

    // This runs ONLY after 3 failed payment attempts
    @Recover
    public void handlePaymentFailure(PaymentException e, String orderId) {
        System.out.println("All retries exhausted for order " + orderId + ". Notifying customer...");
        // Logic to send failure notification, log, etc.
    }
}

In this case, processPayment() will execute 3 times (all throwing PaymentException), and then handlePaymentFailure() will kick in. If on the second or third attempt the payment went through without an exception, the recovery method would never run.
