我在NumberFormatException代码中收到Grails错误，该错误是将电影分类到数据库中。该错误表明它来自cron插件。我做了我的研究，我一直试图通过使用NumberFormatException来捕捉错误，但无济于事。我认为问题在于IndexService。任何帮助将非常感激。
确切的错误是：
2014-07-25 10:09:07,779 [quartzScheduler_Worker-1] ERROR listeners.ExceptionPrinterJobListener - Exception occurred in job: Grails Job

我正在使用：
Grails version: 2.4.2
Groovy version: 2.3.3
JVM version: 1.7.0_51
quartz - 1.0.2
我的代码：

记录域名
package movie
class Record {
//static searchable = true
//data will be recieved via http://www.omdbapi.com/
String artwork
String title
Date dateReleased
String pathToFile
String userRated
String lengthOfFilm
String genre
String plot
float rating
static constraints = {
artwork nullable: true
title nullable: false, unique: true
dateReleased nullable: false
pathToFile nullable: false
userRated nullable: true
lengthOfFilm nullable: true
genre nullable: true
plot nullable: true, maxSize: 2000
rating nullable: true
}
}
最后是IndexJob
package movie
class IndexJob {
static triggers = {
/*
cronExpression: "s m h D M W Y"
| | | | | | `- Year [optional]
| | | | | `- Day of Week, 1-7 or SUN-SAT, ?
| | | | `- Month, 1-12 or JAN-DEC
| | | `- Day of Month, 1-31, ?
| | `- Hour, 0-23
| `- Minute, 0-59
`- Second, 0-59
*/
cron name: "indexTrigger", cronExpression: "0 0/1 * * * ? *"
}
def indexService
def execute() {
indexService.indexFiles()
}
}
答案 0 :(得分：1)
试试这个：
