Quartz为Grails工作只会触发一次 [英] Quartz job for Grails only fires once

问题描述

我正在尝试使用 Quartz插件在我的Grails Web应用程序中设置一个cron作业。我目前只是简单地尝试使用以下代码每秒执行一次测试任务：

  class TestJob {
 private int counter = 0 
 static triggers = {
 simple repeatInterval：1000 
} 
 
 def execute（）{
 //执行作业
 counter + = 1 
 System.out.println（测试cron+计数器）
} 
} 
   execute（）的初始输出调用两次：一次立即在我收到服务器正在运行的提醒之前，以及之后立即发送一次。

有没有人知道为什么我的Quartz作业可能无法正确触发？我尝试过使用cron而不是简单的以及使用不同的参数，时间间隔等。没有任何改变。

我想我有类似的问题。您不得在石英作业中使用 System.out.println 。尝试使用 log.error 。
 
I am trying to setup a cron job in my Grails web application using the Quartz plugin. I am currently simply trying to get a test job to execute once every second using the following code:
class TestJob {
    private int counter = 0
    static triggers = {
        simple repeatInterval: 1000
    }

    def execute() {
        // execute job
        counter += 1
        System.out.println("Testing the cron " + counter)
    }
}
However, when I run the application I only see the initial output of the first execute() call twice: once immediately before I am alerted that the server is running, and once immediately after.

Does anyone know why my Quartz job might not be firing correctly? I have tried using a cron instead of simple as well as using varying parameters, time intervals, etc. Nothing has made a difference. 

Thanks

I think I had similar issues. You are not allowed to use System.out.println from within a quartz-job. Try to use log.error.
