Grails NumberFormatException
我在我的Grails NumberFormatException,grails,groovy,cron,Grails,Groovy,Cron,我在我的Grails代码中收到NumberFormatException错误，该代码用于将电影排序到数据库中。错误表明它来自cron插件。我已经做了研究，我一直试图通过使用NumberFormatException捕捉错误，但没有成功。我认为问题在于索引服务。任何帮助都将不胜感激 确切的错误是： 2014-07-25 10:09:07,779 [quartzScheduler_Worker-1] ERROR listeners.ExceptionPrinterJobListener - Exc

我花了一个小时才弄明白 您发布了太多不相关的代码，很难说出您做错了什么。哪一行抛出异常？哦，对不起，忘记解释了，我看到你有NumberFormatException错误，所以我认为它一定是来自你导入的浮点，所以我所做的就是捕获它并将其设置为0。对不起，我是这个stackoverflow系统的新手！
