Question

我有一个带有Quartz-Scheduler的Java Web应用程序，每天触发一次。但问题是他一次多次请求同一个触发器，有时它说有多个id为“cronTrigger”的实例。

Caused by: org.xml.sax.SAXParseException; lineNumber: 50; columnNumber: 90; cvc-id.2: There are multiple occurrences of ID value 'cronTrigger'.

我的意思是：

Trigger started .....
Trigger started .....
Trigger started .....
Trigger started .....

Trigger started .....
Trigger started .....
Trigger started .....
Trigger started .....

而不是：

Trigger started .....

Trigger started .....

Trigger started .....

Trigger started .....

Trigger started .....

等

我的applicationContext.xml如下所示：

<bean name="schedulerTask" class="com.myapp.struts.triggers.SchedulerTask"></bean>

<bean id="schedulerJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="schedulerTask" />
    <property name="targetMethod" value="execute" />
</bean>

<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
    <property name="jobDetail" ref="schedulerJob" />
    <property name="cronExpression" value="0/10 * * * * ?"/> //for test: scheduler is triggered each 10 seconds
</bean>

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
            <ref bean="cronTrigger"/>
        </list>
    </property>
</bean>

我无法找到问题的来源，也许你们可以帮助我......

我添加了新的applicationContext-scheduler.xml文件，然后将其添加到web.xml中：

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/applicationContext.xml,
        /WEB-INF/applicationContext-scheduler.xml
    </param-value>
</context-param>

唯一运行良好的解决方案。

Spring Quartz-Scheduler不断发出请求
