@Service
public class MyService {
    @Autowired

    @Retryable
    public void doSomething() {
        // 重试的逻辑
    }
}

public class Application {
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        MyService myService = context.getBean(MyService.class);
        myService.doSomething();
    }
}
