我有两个xmls，它有两个独立的Spring批处理作业。 我想从第一个job steplistener调用第二个作业（Bean name＆＃34; extractStepListener＆＃34;）。 我已经在我的第一个（extract.xml）中导入了第二个（transform.xml），以便我可以引用该作业。 当我尝试部署它时，我得到一个重复的作业例外。 如果我在一个xml文件中定义了所有作业，它可以正常工作。

我注册了MapJobRegistry＆amp; transform-tool-context.xml中的BeanPostProcessor 并使用Spring批处理调度程序来定位和运行作业。
以下是摘录
将以下bean添加到
<bean id="jobRegistry" class="org.spr...MapJobRegistry" />
<bean id="jobRegistryBeanPostProcessor" class="org.springframework.batch.core.configuration.support.JobRegistryBeanPostProcessor">
<property name="jobRegistry" ref="jobRegistry"/>
</bean>
添加了以下Spring任务调度程序（为简洁而忽略xmlns）
<task:scheduled-tasks>
<task:scheduled ref="runScheduler" method="run" cron="*/5 * * * * *" />
</task:scheduled-tasks>
