Java 运行作业时，springBatch中的ItemReadListener未运行

我正在学习SpringBatch抛出一个简单的示例，从数据库中读取数据并将其写入xml文件。作业运行正常，但我看不到我放在ItemReadListener中的消息。配置中是否遗漏了某些内容？谢谢你的帮助。我会把最相关的代码，如果需要我可以添加更多

job.xml：

侦听器配置不正确

由此,

 <batch:job id="personJob">
    <batch:step id="step1bb1" >
        <batch:tasklet transaction-manager="transactionManager">
            <batch:chunk reader="itemReader" writer="itemWriter"   commit-interval="10" />
        </batch:tasklet>
    </batch:step>

    <batch:listeners>
        <batch:listener ref="jobPersonListener" />
        <batch:listener ref="personReadListener"/>
    </batch:listeners> 
</batch:job>

应改为

 <batch:job id="personJob">
    <batch:step id="step1bb1" >
        <batch:tasklet transaction-manager="transactionManager">
            <batch:chunk reader="itemReader" writer="itemWriter"   commit-interval="10" />
            <batch:listeners>
             <batch:listener ref="jobPersonListener" />
                 <batch:listener ref="personReadListener"/>
            </batch:listeners> 
        </batch:tasklet>
    </batch:step>
</batch:job>

ItemReadListener实现StepListener接口，而不是JobListener，因此它必须出现在步骤中。

 <batch:job id="personJob">
    <batch:step id="step1bb1" >
        <batch:tasklet transaction-manager="transactionManager">
            <batch:chunk reader="itemReader" writer="itemWriter"   commit-interval="10" />
        </batch:tasklet>
    </batch:step>

    <batch:listeners>
        <batch:listener ref="jobPersonListener" />
        <batch:listener ref="personReadListener"/>
    </batch:listeners> 
</batch:job>

 <batch:job id="personJob">
    <batch:step id="step1bb1" >
        <batch:tasklet transaction-manager="transactionManager">
            <batch:chunk reader="itemReader" writer="itemWriter"   commit-interval="10" />
            <batch:listeners>
             <batch:listener ref="jobPersonListener" />
                 <batch:listener ref="personReadListener"/>
            </batch:listeners> 
        </batch:tasklet>
    </batch:step>
</batch:job>
