Question

几个月前我用Spring Batch制作了一个项目。

此项目工作正常，包括JobExecutionDecider

的实现

public class BatchDecider implements JobExecutionDecider {
private static final Logger log = LoggerFactory.getLogger(BatchDecider.class);

@Autowired
ConfigurationServiceWs config;

public FlowExecutionStatus decide(JobExecution jobExecution, StepExecution stepExecution) {

    if (codition) {

        return new FlowExecutionStatus("AGAIN");
    } else {

        return new FlowExecutionStatus("FINISH");
    }
}

这只有Spring Batch。

现在我必须将它与Spring Boot Batch一起使用。所有过程都正常工作，直到决策步骤。我返回好的FlowExecutionStatus，但我不知道为什么，作业以“FAILED”状态完成。

有人知道为什么不工作？

谢谢！

我找到了解决方案。

我使用决策程序在我的工作上制作一个循环。

我正在使用它：

@Bean(name = "myJob")
public Job importUserJob() {
    return jobBuilderFactory.get("Global Job")
            .incrementer(new RunIdIncrementer())
            .flow(getListeDocMiseADispo())
            .next(decider).on("FINISH").end()

            .next(boucle())
            .next(decider).on("AGAIN").to(boucle())

            .end()
            .build();
}

与此同工：

@Bean(name = "myJob")
public Job importUserJob() {
    return jobBuilderFactory.get("Global Job")
            .incrementer(new RunIdIncrementer())
            .flow(getListeDocMiseADispo())
            .next(decider).on("AGAIN").to(boucle())
            .next(decider).on("FINISH").end()

            .next(boucle())
            .next(decider).on("AGAIN").to(boucle())

            .end()
            .build();
}

但我不知道为什么。也许，Spring-boot-batch-starter更新我的批处理版本并打破它？

有人知道。

使用JobExecutionDecider和spring boot batch
