Spring Quartz��d��调度�C�Z��

淘声依旧 — Wed, 18 Apr 2007 10:33:00 GMT

package com.xzl.quartz;

import org.apache.log4j.Logger;

public class TJob {
    private Logger logger = Logger.getLogger(this.getClass().getName());
    public void doAuth(){
        logger.info("开始进行�Q务调�?验证信息:");
    }
}

1.创徏一个类�Q�类中方法doAuth()�Q�对�q�个�Ҏ��q�行触发

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

<beans>

    <bean id="job" class="com.xzl.quartz.TJob">bean>

    <bean id="jobtask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject">
            <ref local="job"/>
        property>
        <property name="targetMethod">

    <bean id = "cron" class = "org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail">
            <ref bean="jobtask"/>
        property>
        <property name="cronExpression">
            <value>* * 18 * * ?value>
        property>

                <ref local ="cron"/>
            list>
        property>
    bean>

beans>

2.对应的xml�Q�名字JobQuartz.xml [18点的每一分，每一�U�都�q�行doAuth()�Ҏ��的触发]

package com.xzl.quartz;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        System.out.println("��试开�?/span>");
        ApplicationContext ctx = new ClassPathXmlApplicationContext("JobQuartz.xml");
        System.out.println("��试�l�束");

    }

}

3.�q�行��试�Q�只要加载JobQuartz.xml
4.需要加入spring.jar quartz-all-1.6.0.jar log4j-1.2.14.jar commons-collections.jar jta.jar commons-logging.jar�q�几个包
# For JBoss: Avoid to setup Log4J outside $JBOSS_HOME/server/default/deploy/log4j.xml!
# For all other servers: Comment out the Log4J listener in web.xml to activate Log4J.
log4j.rootLogger=INFO, stdout, logfile

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - <%m>%n

log4j.appender.logfile=org.apache.log4j.RollingFileAppender
log4j.appender.logfile.File=logs\\test.log
log4j.appender.logfile.MaxFileSize=512KB
# Keep three backup files.
log4j.appender.logfile.MaxBackupIndex=3
# Pattern to output: date priority [category] - message
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n

5.以上是log4j.properties内容
