配置如下：

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:task="http://www.springframework.org/schema/task"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.1.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd"><context:component-scan base-package="cn.zno" /><task:executor id="threadPoolTaskExecutor" pool-size="1" /><bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"><property name="jobFactory"><bean class="org.springframework.scheduling.quartz.SpringBeanJobFactory" /></property><property name="applicationContextSchedulerContextKey" value="applicationContextKey" /><property name="startupDelay" value="0" /><property name="overwriteExistingJobs" value="true" /><property name="exposeSchedulerInRepository" value="true" /><property name="taskExecutor" ref="threadPoolTaskExecutor" /><property name="triggers"><list><ref bean="cronTrigger_1" /></list></property></bean><bean id="cronTrigger_1"class="org.springframework.scheduling.quartz.CronTriggerFactoryBean"><property name="jobDetail" ref="jobDetail_1" /><property name="cronExpression" value="* * * * * ?" /></bean><bean id="jobDetail_1"class="org.springframework.scheduling.quartz.JobDetailFactoryBean"><property name="jobClass" value="cn.zno.job.Breathe" /></bean><bean id="breath" class="cn.zno.job.Breathe" /> </beans>

為什么要配置這個(gè)

<property name="applicationContextSchedulerContextKey" value="applicationContextKey" />

因?yàn)榭梢酝ㄟ^這個(gè)key取到Spring上下文。

配置1存在的問題：不能自動(dòng)注入。

package cn.zno.job;import org.quartz.Job; import org.quartz.JobExecutionContext; import org.quartz.JobExecutionException; import org.springframework.context.ApplicationContext;import cn.zno.service.AService;public class Breathe implements Job {// @Autowired // private AService aService; @Overridepublic void execute(JobExecutionContext context)throws JobExecutionException {try { // aService.Show();ApplicationContext ctx = (ApplicationContext)context.getScheduler().getContext().get("applicationContextKey");AService aService = ctx.getBean(AService.class);aService.Show();} catch (Exception e) {e.printStackTrace();}}}

?

配置一改：解決自動(dòng)注入問題

change

<property name="jobFactory"><bean class="org.springframework.scheduling.quartz.SpringBeanJobFactory" /></property>

to

<property name="jobFactory"><bean class="cn.zno.common.SpringBeanJobFactory" /></property>

?

cn.zno.common.SpringBeanJobFactory

package cn.zno.common;import org.quartz.spi.TriggerFiredBundle; import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware;public class SpringBeanJobFactory extendsorg.springframework.scheduling.quartz.SpringBeanJobFactory implementsApplicationContextAware {private ApplicationContext applicationContext;@Overridepublic void setApplicationContext(ApplicationContext applicationContext)throws BeansException {this.applicationContext = applicationContext;}@Overrideprotected Object createJobInstance(TriggerFiredBundle bundle)throws Exception {Object jobInstance = super.createJobInstance(bundle);applicationContext.getAutowireCapableBeanFactory().autowireBean(jobInstance);return jobInstance;} }

另一種實(shí)現(xiàn)方式為：

package cn.zno.common;import org.quartz.spi.TriggerFiredBundle; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.config.AutowireCapableBeanFactory;public class SpringBeanJobFactory extendsorg.springframework.scheduling.quartz.SpringBeanJobFactory {@Autowiredprivate AutowireCapableBeanFactory autowireCapableBeanFactory;@Overrideprotected Object createJobInstance(TriggerFiredBundle bundle)throws Exception {Object jobInstance = super.createJobInstance(bundle);autowireCapableBeanFactory.autowireBean(jobInstance);return jobInstance;} }
