jfinal定时任务

实现如下：

1、去quartz官网下载最新的定时任务jar包（http://www.quartz-scheduler.org/）

2、自己实现QuartzPlugin.java文件，代码如下

import static org.quartz.CronScheduleBuilder.cronSchedule;
import static org.quartz.JobBuilder.newJob;
import static org.quartz.TriggerBuilder.newTrigger;
import java.io.IOException;
import java.io.InputStream;
import java.util.Date;
import java.util.Enumeration;
import java.util.Properties;
import org.apache.log4j.Logger;
import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.impl.StdSchedulerFactory;

import com.jfinal.plugin.IPlugin;

/**

• 实现作业的调度
  */
  public class QuartzPlugin implements IPlugin {

private Logger logger = Logger.getLogger(QuartzPlugin.class);
private SchedulerFactory sf = null;
private Scheduler sched = null;
private String config = null;
private Properties properties;

public QuartzPlugin(String config) {
this.config = config;
}

@SuppressWarnings({ "rawtypes", "unchecked" })
public boolean start() {
sf = new StdSchedulerFactory();
try {
sched = sf.getScheduler();
} catch (SchedulerException e) {
new RuntimeException(e);
}
loadProperties();
Enumeration enums = properties.keys();
while (enums.hasMoreElements()) {
String key = enums.nextElement() + "";
if (!key.endsWith("job")) {
continue;
}
String cronKey = key.substring(0, key.indexOf("job")) + "cron";
String enable = key.substring(0, key.indexOf("job")) + "enable";
if (isDisableJob(enable)) {
continue;
}
String jobClassName = properties.get(key) + "";
String jobCronExp = properties.getProperty(cronKey) + "";
Class clazz;
try {
clazz = Class.forName(jobClassName);
} catch (ClassNotFoundException e) {
throw new RuntimeException(e);
}
JobDetail job = newJob(clazz).withIdentity(jobClassName,
jobClassName).build();
CronTrigger trigger = newTrigger()
.withIdentity(jobClassName, jobClassName)
.withSchedule(cronSchedule(jobCronExp)).build();
Date ft = null;
try {
ft = sched.scheduleJob(job, trigger);
sched.start();
} catch (SchedulerException ee) {
new RuntimeException(ee);
}
logger.info(job.getKey() + " has been scheduled to run at: " + ft

• " and repeat based on expression: "
• trigger.getCronExpression());
  }
  return true;
  }

private boolean isDisableJob(String enable) {
return Boolean.valueOf(properties.get(enable) + "") == false;
}

private void loadProperties() {
properties = new Properties();
InputStream is = QuartzPlugin.class.getClassLoader()
.getResourceAsStream(config);
try {
properties.load(is);
} catch (IOException e) {
throw new RuntimeException(e);
}
}

public boolean stop() {
try {
sched.shutdown();
} catch (SchedulerException e) {
logger.error("shutdown error", e);
return false;
}
return true;
}
}

3、创建定时任务

import java.io.File;
import java.util.List;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import com.jfinal.kit.PathKit;
import com.fs.eams.model.InventoryTaskResultRecord;
import com.fs.eams.utils.DateUtils;

public class InventoryQuartzTask implements Job {

public void execute(JobExecutionContext arg0) throws JobExecutionException {
// 内容
}
}

4、properties配置文件内容（名称自定义，我这叫：inventoryQuartzTask.properties）

inventoryQuartzTask.job=com.fs.eams.common.quartzTask.InventoryQuartzTask
inventoryQuartzTask.cron= 0 0 2 * * ?
inventoryQuartzTask.enable=true

每隔5秒执行一次：*/5 * * * * ?

每隔1分钟执行一次：0 */1 * * * ?

每天23点执行一次：0 0 23 * * ?

每天凌晨1点执行一次：0 0 1 * * ?

每月1号凌晨1点执行一次：0 0 1 1 * ?

每月最后一天23点执行一次：0 0 23 L * ?

每周星期天凌晨1点实行一次：0 0 1 ? * L

在26分、29分、33分执行一次：0 26,29,33 * * * ?

每天的0点、13点、18点、21点都执行一次：0 0 0,13,18,21 * * ?

5、jfinal定时任务配置

public void configPlugin(Plugins me) {
/*

• 定时任务
  */
  QuartzPlugin inventoryQuartzTask = new QuartzPlugin("inventoryQuartzTask.properties");
  me.add(inventoryQuartzTask);
  }
