请教一个 Spring 的问题： MethodValidationPostProcessor 是不是和 Scheduled 冲突呀

刚刚提了一个 issue

然后为了方便老哥们看，我直接复制过来

I use the Spring Boot v2.0.5.RELEASE which depends on Spring 5.0.9 Release

I got a problem when I need both MethodValidationPostProcessor and Scheduled

here's the detail.

When I just use Scheduled like below

@SpringBootApplication
@EnableConfigServer
@EnableScheduling
public class SpringConfigServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringConfigServerApplication.class, args);
    }

    @Scheduled(fixedDelay = 5000)
    public void test() {
        System.out.println("Demo");
    }
}

the scheduler works well as what I want. But when I add a MethodValidationPostProcessor like below

@SpringBootApplication
@EnableConfigServer
@EnableScheduling
public class SpringConfigServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringConfigServerApplication.class, args);
    }

    @Bean
    public MethodValidationPostProcessor methodValidationPostProcessor() {
        MethodValidationPostProcessor methodValidationPostProcessor = new MethodValidationPostProcessor();
        methodValidationPostProcessor.setProxyTargetClass(true);
        return methodValidationPostProcessor;
    }

    @Scheduled(fixedDelay = 5000)
    public void test() {
        System.out.println("Demo");
    }
}

the scheduler doesn't work. I have already checked the org.springframework.scheduling.config.ScheduledTaskRegistrar, the scheduler inits as well, but there isn't any task in all of the task variables such as fixedRateTasks, fixedDelayTasks and etc.

Is there any chance that we can use MethodValidationPostProcessor and the scheduler together?
