title: Spring-Retry cannot locate recovery method when implement an interface
body: <p>I found a problem when doing spring-retry with spring boot. When a class implements an interface, it cannot enter the @recover method after exceeding the maximum number of retries. But when I inject a normal class, I can enter this method.Your prompt help and kind advices would be much appreciated,thanks!</p>

  <pre><code>@Service
  public class TestService {
  
      @Retryable(Exception.class)
      public String retry(String c) throws Exception{
          throw new Exception();
      }
  
      @Recover
      public String recover(Exception e,String c) throws Exception{
          System.out.println("got error");
          return null;
      }
  }
  </code></pre>
