Spring +quartz获取ApplicationContext上下文 _application

非淡泊无以明志，非宁静无以致远。这篇文章主要讲述Spring +quartz获取ApplicationContext上下文相关的知识，希望能为你提供帮助。
job存在数据库中，能够进行动态的增增删改查，近期遇到了怎样获取ApplicationContext上下文的问题。解决的方法例如以下
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="https://www.songbingjia.com/android/applicationContextKey"/> < property name="configLocation" value="https://www.songbingjia.com/android/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。能够用applicationContextSchedulerContextKey所定义的key得到相应的spring上下文-->

相应的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"); WebServicePOJOwebService = 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就可以获取ApplicationContext上下文，进而获取相应的bean
