如何在Grails中使用Quartz调度程序？

我正在使用Grails2.3.11，我想在Grails应用程序中执行Quartz调度

为此，我添加了两个库

quartz-all-2.1.1.jar

和

c3p0-0.9.1.1.jar

，但当我运行项目时，它会出现此错误

DEBUG [com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread-#1] BasicResourcePool.attemptRefurbishResourceOnCheckin(1616) | A resource could not be refurbished on checkin. [com.mchange.v2.c3p0.impl.NewPooledConnection@5d12d30f]

关闭日志记录c3p0连接池

在加载连接池之前（在启动计划程序之前）添加此行。

你试过grails的quartz插件吗？是的，我也尝试了quartz插件，但它给了我同样的错误。你能提供你的quartz作业的代码吗？你执行了作为quartz安装一部分的DDL吗？quartz插件（或仅使用quartz）不会创建您所需的表，因为有几个表，您可以添加前缀，使它们与常规表轻松分离。查看使用石英的说明。如果没有安装石英插件或这两个jar，应用程序是否会抛出相同的错误？

Properties p = new Properties(System.getProperties());
p.put("com.mchange.v2.log.MLog", "com.mchange.v2.log.FallbackMLog");
p.put("com.mchange.v2.log.FallbackMLog.DEFAULT_CUTOFF_LEVEL", "OFF"); // Off or any other level
System.setProperties(p);
