java - 如何为 org.quartz.JobDetail 创建自定义编辑器？

Question

我正在尝试使用 Spring 设置 CronTriggerFactoryBean，它有一个名为 JobDetail 的属性，我正在尝试初始化该属性。

  <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>

但是我收到一个错误:

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.

我认为它采用String作为默认类型。

我查看了[propertyeditors][1]。我想我需要使用ClassEditor。我的想法正确吗？

如何消除此错误？我如何为此创建自定义编辑器？

看来您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'

CronTriggerFactoryBean

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

参见 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>
