使用Spring Quartz执行定时��d��

Quartz是OpenSymphony下的一个开源项目，提供了比JDK的TimeTask更强大的定时��d��执行功能�?a target="_blank">Spring在Quartz的基��上包装了一层，使得在不使用数据库配�|�Quartz的情况下�Q�不必再用Quartz的JavaBean讄��参数�Q�代码更优雅�Q�可配置性高�?

下面我就举个��单的例子。首先，配置Spring的配�|�文�Ӟ��起名叫applicationContext.xml

   test.RandomPriceJob




    5












   0 * 11 * * ?

然后�~�写具体操作代码

package test;

import org.apache.log4j.Category;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

/**
* @author shenshan
* @version 1.0
*/
public class RandomPriceJob extends QuartzJobBean
{
private static final Category cat = Category
.getInstance( RandomPriceJob.class );

private int timeout;

/**
* @param timeout
*/
public void setTimeout( int timeout )
{
this.timeout = timeout;
}

/*
* (non-Javadoc)
*
* @see org.springframework.scheduling.quartz.QuartzJobBean�Q�e xecuteInternal(org.quartz.JobExecutionContext)
*/
protected void executeInternal( JobExecutionContext context )
throws JobExecutionException
{
cat.debug( "Job start" );

//执行具体操作

}
}

最后编写运行程�?/p>

package test;

import org.quartz.Scheduler;
import org.quartz.impl.StdSchedulerFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;
import org.springframework.scheduling.quartz.CronTriggerBean;
import org.springframework.scheduling.quartz.JobDetailBean;

/**
* @author shenshan
* @version 1.0
*/
public class RandomPrice
{

public static void main( String[ ] args ) throws Exception
{
  ClassPathResource res = new ClassPathResource( "applicationContext.xml" );
  XmlBeanFactory factory = new XmlBeanFactory( res );
  JobDetailBean job = ( JobDetailBean ) factory
    .getBean( "randomPriceJob" );
  CronTriggerBean trigger = ( CronTriggerBean ) factory
    .getBean( "cronTrigger" );
  Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler( );
  scheduler.start( );
  scheduler.scheduleJob( job, trigger );
}
}

�~�译后运行RandomPrice��OK了。需要注意的是，必须使用main函数才能�q�行�Q�不能��用JUnit�?/p>

附：cronExpression配置说明

Spring IDE Guide

冰雨 — Tue, 25 Apr 2006 07:10:00 GMT

Spring IDE Guide ¶

From: http://springide.org/project/wiki/SpringideGuide

To start working with Spring IDE you need a SpringProject. A SpringProject can be created by adding the SpringProjectNature to an existing project or by creating a new Spring project with the SpringProjectWizard.

Add SpringProject nature ¶

select open project nodes in Eclipse resource navigator or JDT package explorer
activate context menu item "Add Spring Project Nature" on selected projects

once the nature is added, these projects are now decorated with a small 'S' in the upper right corner (overwriting other decorators, e.g. Java project decorator 'J')

to remove the nature, right click the project and select "Remove Spring Project Nature"

Create new SpringProject ¶

open the wizard selection dialog via the menu "File / New / Project..."

select the wizard "Spring IDE / New Spring Project"

enter the project name
(optionally) modify the comma-separated list of supported BeansConfig file extensions (default is "xml")
if you don't need a Java project then deselect the checkbox "Create a Java project"
for a Java project you can change the project's settings (source / classes folder, classpath, libraries, ...) on the next dialog page

Add references to other Spring projects (optional) ¶

open a Spring project's properties dialog from the context menu in Eclipse resource navigator or JDT package explorer
select the properties page "Project References" from the list on the left side
enable all Spring project(s) containing Spring Beans config files which are referenced from within this project via Spring Beans config sets (defined later on)

Add Spring BeansConfig files ¶

open a Spring project's properties dialog from the context menu in Eclipse resource navigator or JDT package explorer
select the properties page "Spring Beans" from the list on the left side

(optionally) modify the comma-separated list of supported BeansConfig file extensions (default is "xml")
use the button "Add..." to open a selector dialog providing a list of all files with the specified extensions in your Spring project and select the corresponding Spring BeansConfig files

once the config files are selected the corresponding files are decorated with a small 'S' in Eclipse resource navigator or JDT package explorer

Create Spring BeansConfig file sets (optional) ¶

open a Spring project's properties dialog from the context menu in Eclipse resource navigator or JDT package explorer
select the properties page "Spring Beans" from the list on the left side
select the second tab labeled "Config Sets"

use the button "New..." to open a dialog for creating a new config set with a selection of all config files (added in the previous step) belonging to this config set
- define a unique name for the config set
- activate the checkbox "Enable bean override" if multiple beans with the same ID should be overidden by the last bean (used by the BeansConfigValidator only -> if activated then bean overriding is not treated as validation error)
- activate the checkbox "Is incomplete" if this config set does not contain all beans which are referenced by other beans defined in this config set (used by the BeansConfigValidator only -> if activated then unresolved bean references are not treated as validation errors)
- externally defined config files (as described in section "Add references to other Spring projects") are decorated with a small blue arrow)

use the buttons "Move Up" and "Move Down" to change the order of the config files within the config set (important for bean overriding)

Open Spring BeansView ¶

select from within any of the added Spring BeansConfig files opened in an Eclipse editor the menu item "Navigate/Show In/Spring Beans"

once the menu item is selected the Spring BeansView is opened and the corresponding Spring BeansConfig file is selected in the view's model

double-clicking on certain entries in the Spring BeansView (bean, property or constructor argument) navigates to the corresponding location in the config file
by selecting the corresponding toolbar actions the BeansView supports alphabetical sorting and syncing with the BeansXmlEditor

Validate Spring BeansConfig file ¶

after modifying and saving any of the added Spring BeansConfig files from within an open Eclipse editor this config is automatically validated by Spring IDE
for any error occured during validation a problem marker is created and listed in Eclipse's problem view

Open Spring BeansGraph ¶

right-clicking on certain entries in the Spring BeansView (config, config set or bean) opens a read-only editor showing a graph with all beans referenced by the selected view entry

Search for Spring Beans ¶

open the search dialog via the "Search / Search..." menu
select the tab "Spring Beans Search" to switch to the BeansSearch dialog
