Question

我正在尝试使用Spring设置CronTriggerFactoryBean，并且它有一个名为 JobDetail 的属性，我试图初始化。

  <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>

但我收到的错误是：

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.

我认为它需要String作为默认类型。

我看一下[propertyeditors][1]。我想我需要使用ClassEditor。我的想法是否正确？

如何删除此错误？如何为此创建自定义编辑器？

Answer 1

您似乎需要传递引用而不是字符串：

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

<强> CronTriggerFactoryBean

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

请参阅 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>

您需要创建转换模式。

将<property name="jobDetail" value="Group Trigger"></property>更改为<property name="jobDetail" ref="myconversion" />

添加转换模式：

<bean id="myconversion" class="org.springframework.scheduling.quartz.JobDetailBean"> 
<property name="jobClass" value="com.nuance.ndm.ou.jobs.MserverCalllogTransformerJob" /> 
<property name="jobDataAsMap"> 
  <map> 
    <entry key="groupTrigger" value="Group Trigger"" />            
  </map> 
</property>

如何为org.quartz.JobDetail创建自定义编辑器？
