我有一个使用Grails开发的Web应用程序。我正在尝试使用quartz1.0-RC9插件为Grails实现一个后台进程，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秒打印一条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
}
}
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
}
}
}
使用命令grails run-app运行时，此方法正常。但是当使用命令grails prod war创建战争并且在Tomcat中部署时，没有任何作用。即使index.html页面没有加载，它也会出现Http-404错误。
我已在BuilConfig.groovy中引用此插件，如插件类别下的文档中所述。
compile ":quartz:1.0-RC9"
但是没有任何作用。
然后我创建了一个新的Grails项目，除了上面提到的石英代码之外什么都没有，并使用grails prod war创建了一个战争。这适用于Tomcat。
我正在使用
Tomcat 6
Grails 2.0.1
石英1.0-RC9
在现有的Grails应用程序中创建作业时我缺少什么？
请有人帮助我。
我在这个问题上做了一些基础工作。在grails dev-war创建我的grails应用程序“Timeprocess”的战争并在Tomcat6下部署时，我在localhost.txt文件中获得以下内容

有人可以帮我指出这里出了什么问题吗？
答案 0 :(得分：2)
我建议做一个：
grails clean
并删除.slcache文件夹，您可以在
下找到该文件夹~/.grails/.slcache
