Question

I am trying to set up the CronTriggerFactoryBeanusing Spring and it has a property named JobDetail which I am trying to initialise.

  <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="name" value="NTrigger"></property>
        <property name="group" value="Group Trigger"></property>
        <property name="jobDetail" value="Group Trigger"></property>
        <property name="cronExpression" value="${quartz.slaPollerCronExpression.timeInterval}"></property>
    </bean>

But I am getting an error as:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name
'cronTriggerForSLAPoller' defined in ServletContext resource [/WEB-INF/config/quartz
-config.xml]: Initialization of bean failed; nested exception is
org.springframework.beans.ConversionNotSupportedException: Failed to convert property value
of type 'java.lang.String' to required type 'org.quartz.JobDetail' for property
'jobDetail'; nested exception is java.lang.IllegalStateException:
Cannot convert value of type [java.lang.String] to required type [org.quartz.JobDetail
for property 'jobDetail': no matching editors or conversion strategy found.

I think it takes String as a default type.

I have a look at the [propertyeditors][1]. I think I will need to use ClassEditor. Am I thinking correct?

How can I remove this error? How can I create a custom editor for this?

Answer 1

It seems you need to pass a reference instead of a string:

Failed to convert property value of type 'java.lang.String' to required type 'org.quartz.JobDetail' for property 'jobDetail'

CronTriggerFactoryBean

/**
 * Set the JobDetail that this trigger should be associated with.
 */
public void setJobDetail(JobDetail jobDetail) {
    this.jobDetail = jobDetail;
}

See Chapter 23. Scheduling and Thread Pooling.

<bean id="exampleJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="exampleBusinessObject" />
    <property name="targetMethod" value="doIt" />
    <property name="concurrent" value="false" />
</bean>


<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
    <property name="jobDetail" ref="exampleJob" />
    <!-- Runs every morning at 6 AM -->
    <property name="cronExpression" value="0 0 6 * * ?" />
</bean>
