本文介绍如何使用Spring框架集成Quartz实现任务调度。通过具体代码示例，展示了配置任务细节及触发器的方法，并实现了每五秒重复执行的任务。

学Spring中接触了Quartz（计划任务调度框架），测试成功后，将简单代码保存在此。

首先导入 log4j quartz slf4j JAR包

package Text;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;
public class MyJob extends QuartzJobBean{
private SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
	@Override
	protected void executeInternal(JobExecutionContext context)
			throws JobExecutionException {
		// TODO Auto-generated method stub
	    String s = (String) context.getJobDetail().getJobDataMap().get("studentName");
		String now=sdf.format(new Date());
		System.out.println(s+"在"+now+"执行了计划任务");
		}
}

<pre name="code" class="java">package Text;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Text {
public static void main(String[] args) {
	ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");

}
}
