聊聊SpringBoot的@Scheduled的并发问题

@Component("aa")
public class aa {
    @Scheduled(cron = "0 44 17 * * ?")
    public void bb() {
        try {
            System.out.println("aa执行时间：" + new Date());
            Thread.sleep(65000);
            System.out.println("aa完成时间：" + new Date());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

@Component("bb")
public class bb {
    @Scheduled(cron = "0 55 17 * * ?")
    public void aa() {
        try {
            System.out.println("bb执行时间：" + new Date());
            Thread.sleep(10000);
            System.out.println("bb完成时间：" + new Date());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
