Spring integration 出站适配器出错后Spring DSL集成流发布消息

我有一个集成流程

IntegrationFlows.from(
            Sftp.inboundAdapter(inboundSftp)
            .localDirectory(this.getlocalDirectory(config.getId()))
            .deleteRemoteFiles(true)
            .autoCreateLocalDirectory(true)
            .filter(new CompositeFileListFilter().addFilter(new LastModifiedLsEntryFileListFilter(config.getRegexFilter())))
            .remoteDirectory(config.getInboundDirectory())
            , e -> e.poller(
                    Pollers.cron(config.getCron())
                    .errorChannel(MessageHeaders.ERROR_CHANNEL).errorHandler((ex) -> {
                        try {

                            this.destroy(String.valueOf(config.getId()));
                            configurationService.removeConfigurationChannelById(config.getId());
                            //loggin here

                            }
                        } catch (Exception ex1) {
                            Logger.getLogger(ExceptionAspect.class.getName()).log(Level.SEVERE, null, ex1);
                        }
                    })
                    .advice(startup.scanRemoteDirectory())
            ))
            .transform(
                file -> util.transform((File) file, config.getSourceEncoding(), config.getTargetEncoding(), doEncoding, doZip))
            .publishSubscribeChannel(s -> s
                .subscribe(f -> {
                    f.handle(Sftp.outboundAdapter(outboundSftp)
                        .useTemporaryFileName(false)
                        .autoCreateDirectory(true)
                        .remoteDirectory(config.getOutboundDirectory()), c -> c.advice(startup.deleteFileAdvice()));

                })
                .subscribe(f -> {

                    if(doArchive) {
                        f.handle(Sftp.outboundAdapter(inboundSftp)
                            .useTemporaryFileName(false)
                            .autoCreateDirectory(true)
                            .remoteDirectory(config.getInboundArchiveDirectory()));
                    } else {
                        f.handle(m -> {});
                    }

                })
                .subscribe(f -> f
                    .handle(m -> {

                        // file transfer logging here
                        if(doArchive) {
                          // file archived logging here
                         }
                        }
                    })
                )
            )
            .get();

在第一个订阅服务器中，如果文件未能上载，则仍会打印日志，该文件将被传输，但实际上并非如此

据我所知，该消息将传递给每个用户，当第一个用户完成其工作时，它将发送给下一个用户

在我的情况下，第一个订户实际上无法上传文件。通知未删除文件

我确实尝试了一些事情

IntegrationFlows.from(
                Sftp.inboundAdapter(inboundSftp)
               ..........
                ))
                .transform(....
                   )
                .publishSubscribeChannel(s -> s
                    .subscribe(f -> {
                        f.handle(Sftp.outboundAdapter(outboundSftp)
                            .useTemporaryFileName(false)
                            .autoCreateDirectory(true)
                            .remoteDirectory(config.getOutboundDirectory()), c -> c.advice(startup.deleteFileAdvice()));

                    }).publishSubcribeChannel(s -> s
                      .subscribe(f -> {

                        if(doArchive) {
                            f.handle(Sftp.outboundAdapter(inboundSftp)
                                .useTemporaryFileName(false)
                                .autoCreateDirectory(true)
                                .remoteDirectory(config.getInboundArchiveDirectory()));
                        } else {
                            f.handle(m -> {});
                        }

                    })
                    .subscribe(f -> f
                        .handle(m -> {

                            // file transfer logging here
                            if(doArchive) {
                              // file archived logging here
                             }
                            }
                        })
                    )
                    )
                )
                .get();

我尝试在outboundAdapter订阅服务器之后再次发布，但错误的是它仍然发布

同时尝试在outboundAdapter订阅服务器中添加.errorChannel，对我无效

根据Artem Bilan的建议，我创建了一个演示应用程序并上传到git repo

服务器配置为

定义了集成流

自述文件我发现了您的问题：

@Bean
public Advice deleteFileAdvice() {

    ExpressionEvaluatingRequestHandlerAdvice advice = new ExpressionEvaluatingRequestHandlerAdvice();
    advice.setOnSuccessExpressionString(AppConstants.SUCCESS_EXPRESSION);
    advice.setTrapException(true);
    return advice;
}

参见其JavaDocs：

/**
 * If true, any exception will be caught and null returned.
 * Default false.
 * @param trapException true to trap Exceptions.
 */
public void setTrapException(boolean trapException) {

---

因此，任何来自消息处理程序的异常，包括SFTP连接失败，都将被吞没。因此，请求消息实际上会移动到

publishSubcribeChannel

配置中的下一个订阅者。

是否有机会看到您关于此问题的一些日志？还不清楚您所谈论的配置的哪一部分…@ArtemBilan我面临第一个订户（包含Sftp.outboundAdapter（outboundSftp））的问题。当我为输出通道设置错误的服务器配置时，Sftp.outboundAdapter（outboundSftp））之后的订阅服务器也会被调用。从技术上讲，这是不可能的，因为默认情况下，

ignoreFailures

为

false

，因此会从失败的订阅中引发异常。如果能看到一些带有该错误的日志就太好了。另外：您使用哪种Spring集成版本？@ArtemBilan Spring boot 2.2.2.RELEASE。Spring集成sftp 5.3.2.1版本。Spring integration ftp 5.3.2.Release如果您说上传过程中出现错误，请共享堆栈跟踪作为对您的问题的编辑。日志在评论中不可读。我添加了这个标志，但它仍然移动到下一个频道。嗯？必须

false

才能重新引发异常。抱歉，我不确定您的逻辑是否正确。按照您的建议将其设置为true。是否有其他方法可以使用？如果它

false

，则会引发异常。请参阅

expressionevaluationRequestHandlerAdvice

源代码。请在

表达式evaluation requestHandlerAdvice.doInvoke（）

中设置断点，以调查调用

回调.execute（）

后的情况，好吗？
