@Scheduled(cron = "0 0 0 ? * 5#3")不支持。

已提交的issue : https://github.com/spring-projects/spring-framework/issues/22436

@Scheduled(cron = "0 0 0 ? * 5#3") 不支持。

代码如下 :

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;

@SpringBootApplication
@EnableScheduling
public class TestScheduledApplication{
    public static void main(String[] args) {
        SpringApplication.run(TestScheduledApplication.class, args);
    }
    @Scheduled(cron = "0 0 0 ? * 5#3")
    public void testScheduled(){
        System.out.println("hello world");
    }
}

报错如下 :
