我有一个使用Grails开发的Web应用程序。我正在尝试实现一个后台进程，该进程使用Grails的quutz1.0-RC9插件每5分钟扫描一次DB中的表。

在尝试编写实际逻辑之前，我正在学习如何使用这个插件，因为我是石英的新手。所以我创建了一个作业，每5秒打印一次带有当前时间戳的消息“hai”。

class checkJob {
    static triggers = {
      simple name:'sampleQuartz', startDelay:10000, repeatInterval: 5000l, repeatCount: -1 // execute job once in 5 seconds
    }

    def execute() {
        println "hai!!!"+new Date()// execute job
    }
}

还有我的QuartzConfig。groovy是

quartz {
    autoStartup = true
    jdbcStore = false
    waitForJobsToCompleteOnShutdown = true
    exposeSchedulerInRepository = false

    props {
        scheduler.skipUpdateCheck = true
    }
}

environments {
    test {
        quartz {
            autoStartup = true
        }
    }
    production {
        quartz {
            autoStartup = true
        }
    }
}

当使用命令grails run-app运行时，这可以正常工作。但是当使用命令grails prod war创建战争并且部署在Tomcat中时，什么都不起作用。即使index.html页面没有加载，它也会出现Http-404错误。

我在BuilConfig中引用了这个插件。groovy，如插件类别下的文档中所述。

compile ":quartz:1.0-RC9"

但什么都不管用。

然后我创建了一个新的Grails项目，它除了上面提到的quartz代码之外什么都没有，并使用Grails prod war创建了一个war。这对Tomcat很管用。

我在用

Tomcat 6
Grails 2.0.1
石英1.0-RC9

在已经存在的grails应用程序中创建作业时我错过了什么？

请有人帮帮我。

我在这个问题上做了一些基础工作。通过grails dev war创建我的grails应用程序“Timeprocess”的war并在Tomcat6下部署，我在localhost中获得了以下信息。txt文件
