Question

我试图在某个步骤中作业失败时配置重启可启动性，然后在解决问题后，它应该能够在重启时从失败的步骤继续。但它没有发生。请在下面找到我的代码。我在这里失踪了什么？

<job id="OneJob" xmlns="http://www.springframework.org/schema/batch" restartable="true">
<listeners>
<listener ref="jobStatusListener" />
</listeners>

<step id="aA" next="bB">
 <tasklet>
     <chunk commit-interval="1000" reader="o_reader" writer="o_writer" />
 </tasklet>
<listeners> <listener ref="stStepListener" /> </listeners>
</step>

<step id="bB" parent="aA">
 <tasklet>
   <chunk commit-interval="1000" reader="t_reader" writer="t_writer" />
</tasklet>
<fail on="FAILED" exit-code="EARLY TERMINATION"/>  
<next on="*" to="cC"/>       
<listeners> <listener ref="stStepListener" /> </listeners>
</step>

<step id="cC">
 <tasklet>
   <chunk commit-interval="1000" reader="th_reader" writer="th_writer" />
 </tasklet>
<listeners> <listener ref="stStepListener" /> </listeners>
</step>
</job>

在第2步中失败（使用不正确的读取语法查询使测试失败）并将状态存储为

BATCH_JOB_EXECUTION.STATUS= FAILED  
BATCH_JOB_EXECUTION.EXIT_CODE=EARLY TERMINATION

解决问题后，当我使用相同的作业参数重新启动时，它失败并将状态存储为

BATCH_JOB_EXECUTION.STATUS= FAILED  
BATCH_JOB_EXECUTION.EXIT_CODE=FAILED

我看到如下例外

尽管已配置Failed元素，为什么重启失败的作业会失败？
