特别注意一点,与Spring3.1以下版本整合必须使用Quartz1,最初我拿2.1.3的,怎么搞都报错:
Caused by: org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [org.springframework.scheduling.quartz.CronTriggerBean] for bean with name 'mytrigger' defined in class path resource [applicationContext.xml]: problem with class file or dependent class; nested exception is java.lang.IncompatibleClassChangeError: class org.springframework.scheduling.quartz.CronTriggerBean has interface org.quartz.CronTrigger as super class
查看发现spring3.0.5中org.springframework.scheduling.quartz.CronTriggerBean继承了org.quartz.CronTrigger(public class CronTriggerBeanextends CronTrigger),而在quartz2.1.3中org.quartz.CronTrigger是个接口(publicabstract interface CronTrigger extends Trigger),而在quartz1.8.5及1.8.4中org.quartz.CronTrigger是个类(publicclass CronTrigger extends Trigger),从而造成无法在applicationContext中配置触发器。这是spring3.1以下版本和quartz2版本不兼容的一个bug。(感谢tiren的回复,spring3.1以及以后版本支持quartz2)
在Spring中使用Quartz有两种方式实现:第一种是任务类继承QuartzJobBean,第二种则是在配置文件里定义任务类和要执行的方法,类和方法仍然是普通类。很显然,第二种方式远比第一种方式来的灵活。
第一种方式的JAVA代码:
- package com.ncs.hj;
- import org.quartz.JobExecutionContext;
- import org.quartz.JobExecutionException;
- import org.springframework.scheduling.quartz.QuartzJobBean;
- public class SpringQtz extends QuartzJobBean{
- private static int counter = 0;
- protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
- System.out.println();
- long ms = System.currentTimeMillis();
- System.out.println("\t\t" + new Date(ms));
- System.out.println(ms);
- System.out.println("(" + counter++ + ")");
- String s = (String) context.getMergedJobDataMap().get("service");
- System.out.println(s);
- System.out.println();
- }
- }
package com.ncs.hj; import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean; public class SpringQtz extends QuartzJobBean{
private static int counter = 0;
protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
System.out.println();
long ms = System.currentTimeMillis();
System.out.println("\t\t" + new Date(ms));
System.out.println(ms);
System.out.println("(" + counter++ + ")");
String s = (String) context.getMergedJobDataMap().get("service");
System.out.println(s);
System.out.println();
}
}
第二种方式的JAVA代码:
- package com.ncs.hj;
- import org.quartz.JobExecutionContext;
- import org.quartz.JobExecutionException;
- import org.springframework.scheduling.quartz.QuartzJobBean;
- import java.util.Date;
- public class SpringQtz {
- private static int counter = 0;
- protected void execute() {
- long ms = System.currentTimeMillis();
- System.out.println("\t\t" + new Date(ms));
- System.out.println("(" + counter++ + ")");
- }
- }
package com.ncs.hj; import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean; import java.util.Date; public class SpringQtz {
private static int counter = 0;
protected void execute() {
long ms = System.currentTimeMillis();
System.out.println("\t\t" + new Date(ms));
System.out.println("(" + counter++ + ")");
}
}
Spring的配置文件:
- <!------------ 配置调度程序quartz ,其中配置JobDetail有两种方式-------------->
- <!--方式一:使用JobDetailBean,任务类必须实现Job接口 -->

关于cronExpression表达式,这里讲解一下:
字段 允许值 允许的特殊字符
秒 0-59 , - * /
分 0-59 , - * /
小时 0-23 , - * /
日期 1-31 , - * ? / L W C
月份 1-12 或者 JAN-DEC , - * /
星期 1-7 或者 SUN-SAT , - * ? / L C #
年(可选) 留空, 1970-2099 , - * /
