我有 2 个不同的触发器和 2 个不同的工作。TimeLord1 和 TimeLord2 是同时处理的 2 个不同的 Java 类，延迟相同，但它们是不同的类。

仅供参考，TimeLord 课程没有任何问题。

我得到了这个例外：

堆栈跟踪

代码

    <bean name="runScheduleJob1" class="org.springframework.scheduling.quartz.JobDetailBean">
            <property name="jobClass" value="service.quartz.RunScheduleJob" />
            <property name="jobDataAsMap">
                <map>
                    <entry key="runScheduleTask1" value-ref="timeLord1" />
                </map>
            </property>
        </bean>

    <bean name="runScheduleJob2" class="org.springframework.scheduling.quartz.JobDetailBean">
            <property name="jobClass" value="service.quartz.RunScheduleJob" />
            <property name="jobDataAsMap">
                <map>
                    <entry key="runScheduleTask2" value-ref="timeLord2" />
                </map>
            </property>
        </bean>

<bean id="simpleTrigger1"
                class="org.springframework.scheduling.quartz.SimpleTriggerBean">
        <property name="jobDetail" ref="runScheduleJob1" />
        <property name="repeatInterval" value="500" />
        <property name="startDelay" value="10" />
    </bean>


<bean id="simpleTrigger2"
                class="org.springframework.scheduling.quartz.SimpleTriggerBean">
        <property name="jobDetail" ref="runScheduleJob2" />
        <property name="repeatInterval" value="500" />
        <property name="startDelay" value="10" />
    </bean>


<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="jobDetails">
            <list>
                <ref bean="runScheduleJob" />
            </list>
        </property>

        <property name="triggers">
            <list>
                <ref bean="simpleTrigger1" />
                <ref bean="simpleTrigger2" />
            </list>
        </property>
    </bean>

尝试取出这部分：

 <property name="jobDetails">
            <list>
                <ref bean="runScheduleJob" />
            </list>
        </property>

您在触发器中定义 jobDetails。
