Question

我做了一份这样的工作。

<batch:job id="parentJob">
    <batch:step id="parentJob.step1">
        <batch:job ref="childJob" job-launcher="batchJobLauncher" />
    </batch:step>
</batch:job>

parentJob将childJob作为一个步骤。我将batchJobLauncher指定为childJob的启动器。

问题是弹出初始化失败并显示此错误消息。

Caused by: java.lang.IllegalArgumentException: JobRepository must be set
    at org.springframework.util.Assert.notNull(Assert.java:112)
    at org.springframework.batch.core.job.AbstractJob.afterPropertiesSet(AbstractJob.java:109)
    at org.springframework.batch.core.configuration.xml.JobParserJobFactoryBean.getObject(JobParserJobFactoryBean.java:86)
    at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.doGetObjectFromFactoryBean(FactoryBeanRegistrySupport.java:142)
    ... 136 more

作业必须有jobRepository的引用，但parentJob没有。

我很好地定义了工作存储库，另一项工作很好。

如果删除了childJob的特定启动器，则弹出初始化成功。

我调试spring代码，我发现JobParserJobFactoryBean类有null JobRepository，所以parentJob也有null。
