我有一个包含三个步骤的Spring Batch作业。第一步运行一次，第二步和第三步运行队列中的每个项目。这份工作的代码：
return jobBuilderFactory.get("job")
.incrementer(new RunIdIncrementer())
.listener(jobListener())
.flow(step1())
.next(step2())
.next(encrypt()).on("CONTINUE")
.to(step2()).on("COMPLETED")
.end().end().build();
重复步骤的步骤执行监听器：
@AfterStep
@Override
public ExitStatus afterStep(StepExecution stepExecution) {
if (queue.size() > 0) {
return new ExitStatus("CONTINUE");
} else {
return new ExitStatus("COMPLETED");
}
}
队列已自动装入。
我的问题是，即使步骤没有失败的退出状态完成，作业仍然以失败的退出状态结束。
我已经调试它以查看作业是否失败，因为步骤完成时退出状态不是“已完成”，但事实并非如此。
有什么想法吗？我认为这可能与其中一个没有某个听众的步骤有关，但我不知道那可能是什么。如有必要，我可以提供更多代码。感谢所有帮助。

很抱歉格式化不完美，我不得不更改其中的一些名称，以确保没有任何敏感信息。
答案 0 :(得分：0)
经过大量调试并阅读Spring Batch的文档后，我发现如果要重复步骤，则必须指定在作业流程中重复的所有步骤，以使作业的状态为COMPLETED。
工作流程应如下所示：
return jobBuilderFactory.get("job")
.incrementer(new RunIdIncrementer())
.listener(jobListener())
.flow(step1())
.next(step2())
.next(encrypt()).on("CONTINUE")
.to(step2())
.next(encrypt()).on("COMPLETED")
.end().end().build();
答案 1 :(得分：0)
我知道我迟到但这可能仍然有帮助。如果您使用决策程序来控制流程而不是步骤退出状态，则可以按照以下方式执行此操作以正确结束作业：
Flow syncStrategyFlow = new FlowBuilder<Flow>("syncStrategyFlow")
.start(componentsHolder.syncFlowDecider) -- one of the decider is responsible for determining if flow should continue
.on(SyncFlowDecider.CONTINUE)
.to(componentsHolder.deltaFilterTypeDecider) -- another decider, in this case its responsible for delegating task to specific step
.on(DeltaFilterTypeDecider.FILTER_TYPE_JOURNAL)
.to(componentsHolder.journalBasedSyncStep)
.next(componentsHolder.syncFlowDecider) --call continuation decider
.on(DeltaFilterTypeDecider.FILTER_TYPE_UPDATE_DATE)
.to(componentsHolder.updateDateBasedSyncStep)
.next(componentsHolder.syncFlowDecider) --call continuation decider
.on(DeltaFilterTypeDecider.FILTER_TYPE_HASH)
.to(componentsHolder.hashBasedSyncStep)
.next(componentsHolder.syncFlowDecider) --call continuation decider
.on(SyncFlowDecider.COMPLETED)
.end()
.build();
jobBuilderFactory.get("syncJob")
.incrementer(new RunIdIncrementer())
.start(syncStrategyFlow)
.end()
.build();
