Spring Quartz-Scheduler多次发出请求

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，他一直在一次多次请求相同的触发器，有时它会说有多个id "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 .....

而不是这样：

Trigger started .....

Trigger started .....

Trigger started .....

Trigger started .....

Trigger started .....

等。

我的applicationContext.xml看起来像这样：

<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>

我找不到问题是从哪里来的，也许你们可以帮我。

Answer 1

我已经添加了新的applicationContext-scheduler.xml文件，然后在web.xml中添加为：

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

唯一有效的解决方案。
