Spring使用Quartz配置调度事务
首先编写服务类:(需要调度的类)
package QuartzTest;import java.util.Date;public class CourseService { public void start(){ System.out.println(new Date().getSeconds()); }}
?

编写调度类,需要继承QuartzJobBean :
package QuartzTest;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;import org.springframework.scheduling.quartz.QuartzJobBean;public class QuartzJob extends QuartzJobBean{ protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException{ courseService.start(); } private CourseService courseService; //使用注入方式获取对象 public CourseService getCourseService(){ return courseService; } public void setCourseService(CourseService courseService){ this.courseService = courseService; } }
?
编写配置文件
需要说明的是,我们有两种trigger,分别是simple和cron模式,simple方式和timertask类似,采用设置interval方式进行调度,而cron可以特有的语法很详细的定制调度执行时间,具体描述在配置文件的注释中
<?xml version="1.0" encoding="UTF-8"?><beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"> <bean id="courseService" ref="courseService"/> <property name="targetObject"> <ref bean="courseService"/> </property> //或者这么写<property name="targetMethod" value="start"/> <property name="targetMethod"> <value>start</value> </property>? //concurrent:对于相同的JobDetail,当指定多个Trigger时, 很可能第一个job完成之前,第二个job就开始了。指定concurrent设为false,多个job不会并发运行,第二个job将不会在第一个job完成之前开始。??? <property name="concurrent" value="false"/> </bean> --> <!-- 配置调度任务,简单模式 <bean id="simpleReportTrigger" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
???? <property name="targetObject">
????? <ref bean="courseService"/>
???? </property>
???? <property name="targetMethod">
??????? <value>start</value>
???? </property>
?? </bean>
配置文件中注释部分。?
spring quartz 需要的包有:spring.jar?? quartz-all-1.6.0.jar?? log4j-1.2.14.jar?? commons-collections.jar?? jta.jar?? commons-logging.jar
