Quartz

1、添加插件：

       compile ":quartz:1.0.2"

2、实现代码：

class InitTranReconciliationJob implements Job{    private Logger log = LoggerFactory.getLogger(InitTranReconciliationJob.class)    static triggers = {        cron name: 'initTranReconciliationTrigger', cronExpression: "0 * 20 * * ?"    }    def group = "initTranReconciliationGroup"    @Override    void execute(JobExecutionContext context) throws JobExecutionException {        Date date = new Date();        log.info("Hello World! - " + date.toLocaleString())        println("Hello World! - " + date.toLocaleString())    }}
