Question

我有一个由宁静引发的直接Camel路线。 restful在Exchange正文中传递文件的名称（需要处理）。路线很简单：

from("direct:myRoute")
   .log("Reading file with name ${in.body}")
   .pollEnrich().simple(inboundUri).timeout(5000)
   .choice()
   .when(body().isNull())
      .log("Cannot read file. Body is null")
   .otherwise()
      .log("Processing file: ${in.headers.CamelFileAbsolutePath}")
   ...

inboundUri是：

smb://DOMAIN;username:password@myLocation/myFolder/?include=${in.body}.csv&delay=5000&noop=true&idempotent=false&readLock=none&recursive=false&sortBy=reverse:file:modified

我第一次触发此路线时，我总是得到＆＃34;无法读取文件。身体是空的＆＃34;。但是，如果我再次触发它，它然后工作正常，文件得到处理。
知道为什么吗？

P.S。我试图在DEBUG模式下设置CAMEL，但我很难理解它的作用。我第一次运行它时得到的结果如下：

DefaultCamelContext : Using ComponentResolver: org.apache.camel.impl.DefaultComponentResolver@1016b44e to resolve component with name: smb
ResolverHelper : Lookup Component with name smb in registry. Found: null
ResolverHelper : Lookup Component with name smb-component in registry. Found: null
DefaultComponentResolver : Found component: smb via type: org.apacheextras.camel.component.jcifs.SmbComponent via: META-INF/services/org/apache/camel/component/smb
DefaultManagementAgent : Registered MBean with ObjectName: org.apache.camel:context=camel-1,type=components,name="smb"
...
PollEnricher : Consumer received no exchange
FilterProcessor : Filter matches: true for exchange: Exchange[ID-server-43626-1517937470434-0-2]

第二次输出更短，主要区别似乎是：

ServiceHelper : Resuming service Consumer[smb://DOMAIN;username:password@myLocation/myFolder/?include=${in.body}.csv&delay=5000&noop=true&idempotent=false&readLock=none&recursive=false&sortBy=reverse:file:modified]
PollEnricher : Consumer received: Exchange[]
FilterProcessor : Filter matches: false for exchange: Exchange[ID-server-43626-1517937470434-0-4]

Answer 1

将入站uri中的延迟值设置为较低的值，因为它的延迟为5000，与您的超时相同，因此无法有足够的时间运行它。将其设置为1000或500或其他。

Camel pollEnrich仅次于第二次
