加载Spring配置文件时，如果Spring配置文件中所定义的Bean类，如果该类实现了ApplicationContextAware接口，那么在加载Spring配置文件时，会自动调用ApplicationContextAware接口中的 public void setApplicationContext(ApplicationContext context) throws BeansException方法，并且自动可获得ApplicationContext 对象。当初始化该类的时候，自动生成上下文对象（ApplicationContext ），Spring配置文件中指定该类，进行初始化。
xml如下：
<bean id="schedulerManage" class="com.isoftskill.zc.task.SchedulerManage" depends-on="schedulerDao" init-method="init" />
程序如下：
package com.isoftskill.zc.task;
import com.isoftskill.zc.constants.SchedulerTypeEnum;
import com.isoftskill.zc.model.dao.SchedulerDao;
import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.impl.StdSchedulerFactory;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import java.util.Date;
import java.util.List;
import java.util.Map;
public class SchedulerManage implements ApplicationContextAware {
private StdSchedulerFactory stdSchedulerFactory = new StdSchedulerFactory();
private ApplicationContext applicationContext;
@Autowired(required = true)//注解，省略get/set方法
private SchedulerDao schedulerDao;
public void init() throws Exception {
Scheduler scheduler = stdSchedulerFactory.getScheduler();
scheduler.start();
List<com.isoftskill.zc.model.vo.Scheduler> schedulers_reports =
schedulerDao.getSchedulerByShType(SchedulerTypeEnum.REPORT_SCHEDULER.getCode());
List<com.isoftskill.zc.model.vo.Scheduler> schedulers_reportwarnings =
schedulerDao.getSchedulerByShType(SchedulerTypeEnum.REPORTWARNING_SCHEDULER.getCode());
for (com.isoftskill.zc.model.vo.Scheduler sh: schedulers_reports) {
saveJob(sh.getShName(), sh.getShTrigger());
}
for (com.isoftskill.zc.model.vo.Scheduler sh: schedulers_reportwarnings) {
saveJob(sh.getShName(), sh.getShTrigger());
}
}
public void saveJob(String beanName, String triggerReg) throws Exception {
Scheduler scheduler = stdSchedulerFactory.getScheduler();
String groupName = "groupName";
scheduler.pauseJob(beanName, groupName);
scheduler.deleteJob(beanName, groupName);
JobDetail job = new JobDetail();
job.setName(beanName);
job.setJobClass(ReportSchedulerJob.class);
Map dataMap = job.getJobDataMap();
dataMap.put("runMeTask", applicationContext.getBean(beanName));
job.setGroup(groupName);
CronTrigger trigger = new CronTrigger();
trigger.setName("trigger_" + beanName);
trigger.setCronExpression(triggerReg);
scheduler.scheduleJob(job, trigger);
}
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext;
}
}
