Question

我已经实现了Spring Batch + Spring Integration与DSL的结合，参考以下链接

https://github.com/cppwfs/spring-batch/blob/1f7cada52aba95bcb23d06bc034b21fe1de0a7a5/spring-batch-docs/asciidoc/spring-batch-integration.adoc#launching-batch-jobs-through-messages

这是代码。

@Bean
public IntegrationFlow integrationFlowUi(JobLaunchingGateway jobLaunchingGateway) {
    return IntegrationFlows.from(Files.inboundAdapter(new File(incomingDirUi)).
                    filter(new SimplePatternFileListFilter("*.csv")).
                    filter(new AcceptOnceFileListFilter<>()),
            c -> c.poller(Pollers.fixedRate(500).maxMessagesPerPoll(1))).
            channel("bridgeChannel").
            handle(fileMessageToJobRequest()).
            handle(jobLaunchingGateway).
            log(LoggingHandler.Level.WARN, "headers.id + ': ' + payload").
            get();
}

批量配置为

@Bean
public Job fundingCardActivationJob() {
    return jobBuilderFactory.get("fundingCardActivationJob")
            .incrementer(new RunIdIncrementer())
            .flow(activationStep())
            .next(fileRenamingStep())
            .end()
            .build();
}

工作运行。但最后它抛出了异常。

我不知道为什么在集成配置似乎完成时会抛出异常。

Answer 1

在JobExecution结果发送到.log()之前，某事正在关闭（或停止）应用程序上下文。

Spring-batch + Integration DSL throw在作业结束后找不到Dispatcher异常
