具有独特 jobParamIncrementer 的 Spring 批处理作业

Question

我为简单的查询编写了一个 spring 批处理应用程序。这在第一次使用某些作业 ID 时可以正常工作，但对于下一次执行，它需要新的作业 ID。对于这个编写的 jobParamIncrementer 类，仍然得到 bean defn not found 异常。我不完全明白发生了什么。请帮帮我。

下面是堆栈跟踪。

            // TODO Auto-generated catch block
            e.printStackTrace();

}

Answer 1

您似乎没有将作业名称传递给 CommandLineJobRunner。 尝试将 JobRunner.main() 方法中对 CommandLineJobRunner.main 的调用更改为：

CommandLineJobRunner.main(new String[] { "applicationContext.xml", "uniqueJob", id});

Answer 2

已解决 :) 在应用程序上下文中的代码行下方添加

<bean id="jobExplorer" class="org.springframework.batch.core.explore.support.JobExplorerFactoryBean">
 <property name="dataSource" ref="dataSource"/>
</bean> 

在 JobRunner.java 中

CommandLineJobRunner.main(new String[] { "applicationContext.xml", "uniqueJob","-next"});

感谢大家的时间和帮助...
