关于spring的quratz任务调度问题
调用的方法
package test;
public class TestQuarz {
public void sayHello() {
System.out.println( "-----------chulai... ");
}
}
测试的类
package test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
public class Test {
public static void main(String[] args) {
ApplicationContext a = new FileSystemXmlApplicationContext(
"WebContent\\WEB-INF\\applicationContext.xml ");
}
}
spring文件配置
<?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= "testQuarz " class= "test.TestQuarz " />
<bean id= "helloworldTask "
class= "org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean ">
<property name= "targetObject ">
<ref bean= "testQuarz " />
</property>
<property name= "targetMethod ">
<value> sayHello </value>
</property>
</bean>
<bean id= "simpleTrigger "
class= "org.springframework.scheduling.quartz.SimpleTriggerBean ">
<property name= "jobDetail " ref= "helloworldTask " />
<property name= "startDelay " value= "1000 " />

<bean

<property name= "triggers ">
<list>
<ref bean= "simpleTrigger " />
</list>
</property>
</bean>
</beans>
我运行test类的时候报这个异常
是怎么回事

[解决办法]
要改两个地方:
1、要把quartz的类包加到classpath中，在spring的安装目录下的lib\quartz\下就有
2、applicationContext.xml文件中增加
<property name= "repeatInterval ">
<value> 1000 </value>
</property>
完整的applicationContext.xml文件如下：
<?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= "testQuarz " class= "test.TestQuarz " />
<bean id= "helloworldTask " class= "org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean ">
<property name= "targetObject ">
<ref bean= "testQuarz " />
</property>
<property name= "targetMethod ">
<value> sayHello </value>
</property>
</bean>
<bean id= "simpleTrigger " class= "org.springframework.scheduling.quartz.SimpleTriggerBean ">
<property name= "jobDetail " ref= "helloworldTask " />
<property name= "startDelay " value= "1000 " />
<property name= "repeatInterval ">
<value> 1000 </value>
</property>
</bean>
<bean class= "org.springframework.scheduling.quartz.SchedulerFactoryBean ">
<property name= "triggers ">
<list>
<ref bean= "simpleTrigger " />
</list>
</property>
</bean>
</beans>
