项目需要用一些少量的后台调度任务，上周末再完全用jfinal重现项目的时候把quartz替换成了cron4j。虽然以前没用过cron4j但是感觉自己需要的简单功能用这个轻巧的jar包就足够了。刚开始是在一个servlet 监听器里面启动调度程序。后来想完全可以依赖于Jfinal的插件机制做一点点小扩展。献丑直接上代码。

另外cron4j替换quartz会不会出什么问题我也不清楚。求指教。

如果需要的话再弄个QuartzPlugIn

package com.jfinal.plugin.cron;import it.sauronsoftware.cron4j.Scheduler;import com.jfinal.plugin.IPlugin;public class Cron4jPlugIn implements IPlugin {private final Scheduler scheduler = new Scheduler();@Overridepublic boolean start() {scheduler.start();return true;}@Overridepublic boolean stop() {scheduler.stop();return true;}public void addTask(String cronExpress, Runnable task) {scheduler.schedule(cronExpress, task);}}

/*** 配置插件*/public void configPlugin(Plugins me) {C3p0Plugin c3p0Plugin = new C3p0Plugin(getProperty("jdbcUrl"), getProperty("user"), getProperty("password"));me.add(c3p0Plugin);ActiveRecordPlugin arp = new ActiveRecordPlugin(c3p0Plugin);me.add(arp);arp.addMapping("mobilebind", MobileBind.class);arp.addMapping("sendrecord", SendRecord.class);arp.setShowSql(true);SqlReporter.setLogger(true);Cron4jPlugIn cron4jPlugIn = new Cron4jPlugIn();if (getPropertyToBoolean("SendStudentInfo.enable") == true) {cron4jPlugIn.addTask(getProperty("SendStudentInfo.cron"), new SendStudentInfoTask());}if (getPropertyToBoolean("SmsUpReceive.enable") == true) {cron4jPlugIn.addTask(getProperty("SmsUpReceive.cron"), new SmsUpReceiveTask());}me.add(cron4jPlugIn);}
