问题
I followed this question after getting ExhaustedRetryException on @Retryable function. The @Retryable function is retrying.
Here's the Delegate with the @Retryable function:
@Component
public class OrderRequestDelegate {
private static final Logger LOGGER = LoggerFactory.getLogger(OrderRequestDelegate.class);
private final OrderRequestDao orderRequestDao;
private final SqsQueueDao sqsQueueDao;
@Autowired
public OrderRequestDelegate(OrderRequestDao orderRequestDao, SqsQueueDao sqsQueueDao) {
this.orderRequestDao = orderRequestDao;
this.sqsQueueDao = sqsQueueDao;
}
@Retryable(include=NoResultException.class, backoff = @Backoff(delay = 100, maxDelay = 101), maxAttempts = 5)
public OrderRequest processItem(String storeId, String message) {
Long id = 999L;
OrderRequest result = orderRequestDao.findOne(id);
if (result == null) {
LOGGER.info("Tried in retryable");
throw new NoResultException();
}
return result;
}
@Recover
public void recover(NoResultException e, Long id) {
LOGGER.info("recover triggered");
}
@Recover
public void recover(Exception e, Long id) throws Exception {
LOGGER.info("retry failure");
}
}
Here's the class with the caller of the function:
@RestController
@RequestMapping("/orderRequests")
@Api(description = "orders API")
public class OrderRequestController {
private static final Logger LOGGER = LoggerFactory.getLogger(OrderRequestController.class);
private final OrderRequestDelegate orderRequestDelegate;
@Autowired
public OrderRequestController(OrderRequestDelegate orderRequestDelegate) {
this.orderRequestDelegate = orderRequestDelegate;
}
//...
@ApiOperation(value="test function")
@RequestMapping(method = RequestMethod.GET)
public String get() {
orderRequestDelegate.processItem("100", "abc");
return String.format("Worked");
}
}
And the Application class that includes the @EnableRetry annotation:
@SpringBootApplication
@EnableRetry
public class FulfillmentApplication extends SpringBootServletInitializer {
private static final Logger LOGGER = LoggerFactory.getLogger(FulfillmentApplication.class);
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(FulfillmentApplication.class);
}
public static void main(String[] args) {
LOGGER.debug("Starting Spring application main...");
SpringApplication.run(FulfillmentApplication.class, args);
}
}
Here's the stacktrace when I run the @Retryable function:

Here's the complete app from that answer, modified to be functionally equivalent to yours; if you still can't figure out what's wrong, edit your question with complete configuration and a debug log.
@SpringBootApplication
@EnableRetry
public class So38601998Application {
public static void main(String[] args) {
ConfigurableApplicationContext context = SpringApplication.run(So38601998Application.class, args);
Foo bean = context.getBean(Foo.class);
try {
bean.out("foo");
System.out.println("Recovered");
}
catch (Exception e) {
System.out.println("Not recovered: " + e);
}
try {
bean.out("bar");
}
catch (Exception e) {
System.out.println("Not recovered: " + e);
}
}
@Component
public static class Foo {
@Retryable(include=NoResultException.class, backoff = @Backoff(delay = 100, maxDelay = 101), maxAttempts = 5)
public void out(String foo) {
System.out.println(foo);
if (foo.equals("foo")) {
throw new NoResultException();
}
else {
throw new IllegalStateException();
}
}
@Recover
public void connectionException(NoResultException e) {
System.out.println("Retry failure");
}
@Recover
public void connectionException(Exception e) throws Exception {
System.out.println("Retry failure");
throw e;
}
}
}

回答2:
Looks Like you just missed the basic part like i did.
The method annotated with @Recover should take The same type of argument (and optional Throwable or its subclass typed argument). Beside that the The return type should also be the same.
Here is how your recover method should look like to be fired after the retry exhausted.
@Component
public static class Foo {
@Retryable(include=NoResultException.class, backoff = `@Backoff(delay = 100, maxDelay = 101), maxAttempts = 5)`
public void out(String foo) {
System.out.println(foo);
if (foo.equals("foo")) {
throw new NoResultException();
}
else {
throw new IllegalStateException();
}
}
@Recover
public void connectionException(NoResultException e, String foo) {
System.out.println("Retry failure");
}
@Recover
public void connectionException(Exception e, String foo) throws Exception {
System.out.println("Retry failure");
throw e;
}
}
