Spring +quartz获取ApplicationContext上下文

Spring +quartz获取ApplicationContext上下文

job存在数据库中，可以进行动态的增增删改查，最近遇到了如何获取ApplicationContext上下文的问题，解决办法如下

applicationContext-quartz.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">

<beans>
    <bean name="quartzScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="applicationContextSchedulerContextKey" value="applicationContextKey"/>
        <property name="configLocation" value="classpath:quartz.properties"/>
    </bean>
</beans>

<!-- applicationContextSchedulerContextKey： 是 org.springframework.scheduling.quartz.SchedulerFactoryBean这个类中把spring上 下 文以key/value的方式存放在了quartz的上下文中了，可以用 applicationContextSchedulerContextKey所定义的key得到对应的spring上下文 -->

  

对应的job任务

public class QuartzJobBean implements Job {


/* (non-Javadoc)
 * @see org.quartz.Job#execute(org.quartz.JobExecutionContext)
 */
@Override
public void execute(JobExecutionContext jobContext) throws JobExecutionException {


String jobId = jobContext.getJobDetail().getDescription();
String serviceId = jobContext.getTrigger().getDescription();


ApplicationContext applicationContext=null;
try {
applicationContext=getApplicationContext(jobContext);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
WebServiceService webServiceService = (WebServiceService) applicationContext.getBean("webServiceService");
WebServicePOJO  webService = webServiceService.getWebService(serviceId);
ScheduleService.schedule(webService.getNameSpace(), webService.getServiceName(), webService.getWsdlURL(), webService.getMethod());
}

private static final String APPLICATION_CONTEXT_KEY = "applicationContextKey";
private ApplicationContext getApplicationContext(JobExecutionContext context) throws Exception {
ApplicationContext appCtx = null;
appCtx = (ApplicationContext) context.getScheduler().getContext().get(APPLICATION_CONTEXT_KEY);
if (appCtx == null) {
throw new JobExecutionException("No application context available in scheduler context for key \"" + APPLICATION_CONTEXT_KEY + "\"");
}
return appCtx;
}


}

APPLICATION_CONTEXT_KEY的值是第一个XML中配置的值，通过getApplicationContext方法传入quartz的context即可获取ApplicationContext上下文，进而获取对应的bean
