从Spring批处理中的另一个xml导入Job

Question

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。

extract.xml

Answer 1

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

变换刀具context.xml中

<bean id="jobRegistry" class="org.spr...MapJobRegistry" />

<bean id="jobRegistryBeanPostProcessor" class="org.springframework.batch.core.configuration.support.JobRegistryBeanPostP‌​rocessor">
    <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）

变换刀具scheduler.xml

<task:scheduled-tasks>
        <task:scheduled ref="runScheduler" method="run" cron="*/5 * * * * *" />
   </task:scheduled-tasks>

RunScheduler.java

@Component
public class ExtractStepListener  {

    @Autowired
    private JobLauncher jobLauncher;
    @Autowired
    private JobLocator jobRegistry;

    public void run() {

        try {
                JobParameters param = new JobParametersBuilder().toJobParameters();
                jobLauncher.run(jobRegistry.getJob("extract"), param);
                jobLauncher.run(jobRegistry.getJob("transformationJob"), param);

            } catch (Exception e) {
            System.out.println("Error occured while launching transform");
            e.printStackTrace();
        }

    }   
}
