Quartz+spring实例应用

1. javabean类

在Test.QuartzJob中

package Test;

public class QuartzJob {
public void work()
{
System.out.println("Quartz的任务调度！！！");
}
}

2. 设置Spring的xml

我新建了一个applicationContext_quartz.xml，内容如下：

<?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:jee="http://www.springframework.org/schema/jee"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.0.xsd"> 
<!-- 要调用的工作类 -->
<bean id="quartzJob" class="Test.QuartzJob"></bean>
<!-- 定义调用对象和调用对象的方法 -->
<bean id="jobtask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<!-- 调用的类 -->
<property name="targetObject">
<ref bean="quartzJob"/>
</property>
<!-- 调用类中的方法 -->
<property name="targetMethod">
<value>work</value>
</property>
</bean>
<!-- 定义触发时间 -->
<bean id="doTime" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail">
<ref bean="jobtask"/>
</property>
<!-- cron表达式 -->
<property name="cronExpression">
<!-- 每隔10秒执行一次-->
<value>0/10 * * * * ?</value>
</property>
</bean>
<!-- 总管理类 如果将lazy-init='false'那么容器启动就会执行调度程序 -->
<bean id="startQuertz" lazy-init="false" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="doTime"/>
</list>
</property>
</bean>

</beans>

3. 设置web.xml对Spring加载

<!-- 加载spring -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/classes/applicationContext*.xml
</param-value>
</context-param>
<servlet>
<servlet-name>context</servlet-name>
<servlet-class>
org.springframework.web.context.ContextLoaderServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

注意：1.导入quartz-all-1.5.2.jar 下载http://download.csdn.net/source/1026766

2.导入spring.jar（我用的是spring2.0以前的版本） 下载http://download.csdn.net/source/1041819

如果不导入的话

org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean

org.springframework.scheduling.quartz.CronTriggerBean

org.springframework.scheduling.quartz.SchedulerFactoryBean

spring中的这三个类找不到，spring不能正常加载，由于第一次使用Quartz，我就是当时忽略了这一点，浪费了很多时间来调配置，其实配置一点没有错误。

3. 你会问为什么用spring后就不用

quartz.properties

quartz-jobsxml

这两个文件了么？

我回答：是的，它会自动找到quartz包中默认的这两个文件，如果你有特殊需要，也可以自己定义这两个文件。

附：quartz.properties

#
# Configure Main Scheduler Properties
#

org.quartz.scheduler.instanceName = TestScheduler
org.quartz.scheduler.instanceId = one

#
# Configure ThreadPool
#

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 5
org.quartz.threadPool.threadPriority = 4

#
# Configure JobStore
#

#org.quartz.jobStore.misfireThreshold = 5000

#org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

# ===========================================================================
# Configure SchedulerPlugins ===============================================
# ===========================================================================
#org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingTriggerHistoryPlugin
#org.quartz.plugin.triggHistory.triggerFiredMessage = Trigger {1}.{0} fired job {6}.{5} at: {4, date, HH:mm:ss MM/dd/yyyy}
#org.quartz.plugin.triggHistory.triggerCompleteMessage = Trigger {1}.{0} completed firing job {6}.{5} at {4, date, HH:mm:ss MM/dd/yyyy} with resulting trigger instruction code: {9}

org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializationPlugin
org.quartz.plugin.jobInitializer.fileName =quartz_jobs.xml
org.quartz.plugin.jobInitializer.overWriteExistingJobs = false
org.quartz.plugin.jobInitializer.failOnFileNotFound = true

org.quartz.plugin.shutdownhook.class = org.quartz.plugins.management.ShutdownHookPlugin
org.quartz.plugin.shutdownhook.cleanShutdown = true

系统会根据配置文件找到quartz_jobs.xml
