Apache camel Apache Camel multiple pollenrich（）和移动参数错误

我使用的是ApacheCamel版本2.21.1，我在使用该版本时遇到了问题 从ftp下载特定文件。当我用pollRich下载2个文件时，操作需要几分钟（4分钟），在.done目录中移动第一个文件时，camel出错。 我有一个例外：

这是我的路线：

         from(queueSource)
            .errorHandler(deadLetterChannel("direct:dead")
               .useOriginalMessage()
               .maximumRedeliveries(3)
               .redeliveryDelay(180000)
               .retryAttemptedLogLevel(LoggingLevel.WARN)
            )
            .unmarshal().json(JsonLibrary.Jackson,MyClass.class)
            .process(setHeaderWithMyVariableProcessorClass)
            .choice()
                .when(header("DownloadFilename").isEqualTo(true))
                  .pollEnrich()
                   .simple("{{ftp.path}}
                    &useList=false
                    &consumer.bridgeErrorHandler=true
                    &autoCreate=false
                    &username={{ftp.username}}&password={{ftp.password}}             
                    &passiveMode=true
                    &localWorkDirectory={{ftp.localWorkDirectory}}
                    &maxMessagesPerPoll=1
                    &disconnectOnBatchComplete=true
                    &move={{ftp.fullFileDir}}/.done
                    &soTimeout=600000
                    &fileName=${body.getFileAssetName()}")                          
                .aggregationStrategy(new ApplyOldExchangeAggregationStrategy())
                .end()
               .end()
              .choice()
                .when(header("DownloadAttach0").isEqualTo(true))
                  .pollEnrich()
                   .simple("{{ftp.attachmentspath}}&.....&soTimeout=600000&fileName=${body.getAttachmentList()[0]}")
                   .aggregationStrategy(new ApplyOldExchangeAggregationStrategy())
                   .end()
                  .end()                                    
                 .log("<<<<<< ${body} >>>>>>>")                 
                .end();

from（队列源）
.errorHandler（死信通道（“直接：死信”）
.useOriginalMessage（）
.最大可再交付量（3）
.重新交付显示（180000）
.retryAttemptedLogLevel（LoggingLevel.WARN）
)
.unmarshal（）.json（JsonLibrary.Jackson，MyClass.class）
.process（setHeaderWithMyVariableProcessorClass）
.choice（）
.when（标题（“下载文件名”）.isEqualTo（true））
.poll（）
.simple（{ftp.path}
&useList=false
&consumer.bridgeErrorHandler=true
&自动创建=错误
&用户名={{ftp.username}}和密码={{ftp.password}}
&被动模式=真
&localWorkDirectory={{ftp.localWorkDirectory}
&maxMessagesPerPoll=1
&DisconnectionBatchComplete=true
&move={ftp.fullFileDir}}/.done
&soTimeout=600000
&文件名=${body.getFileAssetName（）}”）
.aggregationStrategy（新的ApplyOldExchangeAggregationStrategy（））
(完)
(完)
.choice（）
.when（标题（“下载附件0”）.isEqualTo（真））
.poll（）
.simple（“{ftp.attachmentspath}&….&soTimeout=600000&fileName=${body.getAttachmentList（）[0]}”）
.aggregationStrategy（新的ApplyOldExchangeAggregationStrategy（））
(完)
(完)
.log（“>>”）
.end（）；

您可以尝试使用

.pollRich（）.simple（“ftp://...“”.cacheSize（-1）

@Bedla感谢您的建议，但我在缓存大小方面有另一个错误：org.apache.camel.component.file.GenericFileOperationFailedException:文件操作失败：空连接未打开。代码：221，当应用程序等待几分钟以提交交换并移动.done目录中的第一个文件时，似乎有些东西不起作用。我将尝试更改对错误的描述，因为我发现问题不在soTimeout中
