java - org.springframework.beans.factory.NoSuchBeanDefinitionException : No unique bean of type [org.quartz.JobDetail]已定义

Question

运行 Spring 应用程序时出现以下异常:

org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of 
type [org.quartz.JobDetail] is defined: expected single matching bean but found 2: 
[quartzSchedulerRuntime, jobDetail]

这是我在root-context.xml中配置quartz的部分.

root-context.xml

<bean name="quartzSchedulerRuntime" class="org.springframework.scheduling.quartz.JobDetailBean">
    <property name="jobClass" value="com.task.QuartzScheduler" />
    <property name="jobDataAsMap">
        <map>
            <entry key="runtimeReportServiceImpl" value-ref="RuntimeReportService"  />
        </map>
    </property>
</bean> 


    <bean id="cronTriggerRuntime"
        class="org.springframework.scheduling.quartz.CronTriggerBean">

        <property name="jobDetail" ref="quartzSchedulerRuntime" />
        <property name="cronExpression" value="0 30 12 ? * MON *" />

</bean>


    <bean id="quartzScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" lazy-init="false">
    <property name="schedulerContextAsMap">
        <map>
        <entry key="reportSchedulerServiceImpl" value-ref="reportSchedulerServiceImpl"></entry>
        </map>
        </property>
    <property name="jobDetails">
       <list>
          <ref bean="quartzSchedulerRuntime" />
          <ref bean="jobDetail"/>
       </list>
    </property>

    <property name="triggers">
        <list>
        <ref bean="cronTriggerRuntime" />
        <ref bean="jobTrigger"/>
        </list>
    </property>

    </bean>

    <bean id="jobDetailFactory"
    class="org.springframework.beans.factory.config.ObjectFactoryCreatingFactoryBean">
    <property name="targetBeanName">
        <idref local="jobDetail" />
    </property>

    </bean>

    <bean id="jobDetail" class="org.springframework.scheduling.quartz.JobDetailBean"
    scope="prototype">
    <property name="jobClass" value="com.scheduler.SMTPMailJob " />

     <property name="jobDataAsMap">
        <map>
          <entry key="reportSchedulerServiceImpl" value-ref="reportSchedulerServiceImpl" />
          <entry key="filterUtil" value-ref="filterUtil" />
          <entry key="reportService" value-ref="reportService" />
          <entry key="fusionChartHtmlToImage" value-ref="fusionChartHtmlToImage"/>
          <entry key="fcproperties" value-ref="fcproperties"/>
         </map>
      </property>
    </bean>

    <bean id="jobTriggerFactory"
    class="org.springframework.beans.factory.config.ObjectFactoryCreatingFactoryBean">
    <property name="targetBeanName">
        <idref local="jobTrigger" />
    </property>
    </bean>

    <bean id="jobTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean" scope="prototype">
    <property name="jobDetail" ref="jobDetail" />
    <property name="cronExpression" value="0 0 9 1/1 * ? *" /> 
    </bean>

编辑:我已将问题范围缩小到此。我创建了一个名为 RScheduler 的类，用于安排作业。在该类(class)中我已经声明:

Scheduler scheduler;
ObjectFactory<JobDetail> jobDetailFactory;
ObjectFactory<CronTrigger> jobTriggerFactory;

    @Autowired
    public ReportScheduler(Scheduler scheduler,ObjectFactory<JobDetail> jobDetailFactory,ObjectFactory<CronTrigger> jobTriggerFactory)
            throws SchedulerException 
            {
        Assert.notNull(scheduler, "scheduler cannot be null");
        Assert.notNull(jobDetailFactory, "jobDetailFactory cannot be null");
        Assert.notNull(jobTriggerFactory, "jobTriggerFactory cannot be null");
        this.scheduler = scheduler;
        this.jobDetailFactory=jobDetailFactory;
        this.jobTriggerFactory=jobTriggerFactory;
        this.scheduler.getContext().put("reportSchedulerServ", reportSchedulerServ);
        }

我用另一种方法调用该作业，例如:

JobDetail jobDetail = jobDetailFactory.getObject();

这是给我错误的行。

编辑2:我猜问题是我需要触发许多作业。所以我创建了

ObjectFactory<JobDetail> jobDetailFactory

通过jobDetailFactory捕获物体 bean 。我认为，该行

JobDetail jobDetail = jobDetailFactory.getObject()

无法确定要获取哪个 JobDetail bean，因为它有两个作业详细信息。我不明白@Qualifier怎么了符号将有助于确定这一点。我可以解决这个错误的任何特定方法..？

Answer 1

如您所见，您定义了两个具有相同类型的 bean:

jobDetail 和quartzSchedulerRuntime 属于这种类型org.springframework.scheduling.quartz.JobDetailBean

您可以通过名称(quartzSchedulerRuntime/jobDetail)来区分它们，但如果您通过类型(...JobDetailBean) Autowiring 它们，那就很模糊了。
