java---定时任务@Scheduled注解报错：Encountered invalid @Scheduled method ‘xxx‘: For input string: ““

ssm框架，做定时任务，一直报这个错误
Encountered invalid @Scheduled method ‘setTimeAgain’: For input string: ""En

加上下边这个就Ok了

@Bean
    public TaskScheduler scheduledExecutorService() {
    
    
        ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
        scheduler.setPoolSize(8);
        scheduler.setThreadNamePrefix("scheduled-thread-");
        
        return scheduler;
    }
