Question

我创建了两个集成流程，一个是File inbound flow，它是查找我的本地目录，另一个是Sftp outbound flow，它将这些文件从本地发送到远程目录。我正在从Main类运行这些流，即不使用Junit。那么我如何从File Inbound流向Sftp outblound流发送消息。在Junit测试方法中，我可以使用send（）方法进行文件传输，但在这种情况下无法发送文件。所以任何人都可以帮助我，因为我无法继续。

这是我的文件入站流程..

@Bean
public IntegrationFlow sftpOutboundFlow() {
    System.out.println("enter out  bound flow.....");
    return IntegrationFlows
            .from("toSftpChannel")
            .handle(Sftp.outboundAdapter(this.sftpSessionFactory)
                    .remoteFileSeparator("\\")
                    .useTemporaryFileName(false)
                    .remoteDirectory(remDir)).get();
}

这是我的sftp出境流程..

@Bean
public IntegrationFlow fileReadingFlow() {          
    return IntegrationFlows
            .from("fileReadingResultChannel")
            .transform(Transformers.fileToByteArray())
            .handle(Sftp.outboundAdapter(this.sftpSessionFactory)
                    .remoteFileSeparator("\\")
                    .useTemporaryFileName(false)
                    .remoteDirectory(remDir))
            //.channel(this.fileReadingResultChannel)
                    .channel(MessageChannels.direct("fileReadingResultChannel"))
            .get();
}

正如加里所说，我的新流程是......


org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'fileReadingFlow' defined in class src.SftpOutBoundDsl: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.integration.dsl.IntegrationFlow]: Factory method 'fileReadingFlow' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: The 'currentComponent' (org.springframework.integration.file.remote.handler.FileTransferringMessageHandler@629a) is a one-way 'MessageHandler' and it isn't appropriate to configure 'outputChannel'.

错误日志是......

Answer 1

将入站适配器通道更改为使用...

MessageChannels.direct("fileReadingResultChannel")

并将两个流连接在一起......

return IntegrationFlows
        .from("fileReadingResultChannel")
        .handle(...

修改：

.channel（MessageChannels.direct（＆＃34; fileReadingResultChannel＆＃34））

出站渠道适配器不会产生任何结果，因此您无法通过渠道跟踪它。

错误信息对我来说非常清楚......

... FileTransferringMessageHandler ...是一个单向的MessageHandler＆＃39;并且配置＆quot; outputChannel＆＃39;是不合适的。这是整合流程的结束。

...但如果您认为需要澄清，请告诉我们。

如果您希望在文件传输后继续流，请在变换器后添加publishSubscribeChannel，如果文件传输成功，则消息将转到另一个订户（流）。
