Java Spring批处理未能序列化类型为org.springframework.Batch.core.StepExecution的对象

java spring spring-batch

Java Spring批处理未能序列化类型为org.springframework.Batch.core.StepExecution的对象,java,spring,spring-batch,Java,Spring,Spring Batch,我有一个Spring批处理作业，它现在给我一个错误：未能序列化以下类型的对象：class org.springframework.batch.core.StepExecution作业侦听器正在打印以下异常： org.springframework.batch.core.JobExecutionException: Flow execution ended unexpectedly at org.springframework.batch.core.job.flow.FlowJob.doExec

我有一个Spring批处理作业，它现在给我一个错误：未能序列化以下类型的对象：class org.springframework.batch.core.StepExecution作业侦听器正在打印以下异常：

配置如下：

  <job id="job2" restartable="false" job-repository="jobRepository" parent="baseJob">
<step id="job2StepBootstrap" parent="parentJobStep">
  <tasklet ref="job2TaskBootstrap"  transaction-manager="jobsTransactionManager" />
</step>
<listeners>
  <listener ref="job2JobListener"/>
</listeners>

我添加了job2TaskBootstrap，您可以看到即使是精简版也无法工作

步骤中使用的一个或多个类在类声明中缺少

implements Serializable

保存到

jobRepository

的任何内容都需要可序列化。这可以用作保存的步骤执行上下文数据的一部分。

我正在使用以下命令将类的对象放入tasklet中的chunkContext中：-

chunkContext.getStepContext().getStepExecution().getJobExecution()
          .getExecutionContext().put("objectToBeStored", obj);

假设这个

obj

属于

class A

，那么我使

A实现了可序列化

，这个错误就消失了。

请共享完整的堆栈跟踪，jobListener不显示完整的堆栈跟踪添加了完整的堆栈跟踪..sun.nio.fs.WindowsPath不可序列化。使用字符串/URI/URL/java.io.File来存储类似问题的pathsee，正如您可以从我在这里发布的配置中看到的，我已经正确地将作业存储库配置为内存中。我不需要保存作业，直到不将任何内容保存到数据库，并且保存在上下文中的所有对象都实现了可序列化接口。当然，您是对的，保存在上下文中的一个对象它的超类有一个Path类型的变量，它不是可序列化的完美解释，除此之外，如果您要在applicationContext中放入任何内容供以后使用，则还需要序列化
