Using Local Work Directory Camel JCIFS supports consuming from remote servers and downloading the files directly into a local work directory.

Camel JCIFS will store to a local file with the same name as the remote file. And finally, when the [Exchange] is complete the local file is deleted.

Using Local Work Directory
Camel JCIFS supports consuming from remote servers and downloading the files directly into a local work directory. This avoids reading the entire remote file content into memory as it is streamed directly into the local file using FileOutputStream.
Camel JCIFS will store to a local file with the same name as the remote file. And finally, when the Exchange is complete the local file is deleted.
So if you want to download files from a remote server and store it as files then you need to route to a file endpoint such as:
| Code Block | ||||
|---|---|---|---|---|
| ||||
from("smb://foo@myserver.example.com/sharename?password=secret&localWorkDirectory=/tmp")
.to("file://inbox");
{code}

| Tip | ||

The route above is ultra efficient as it avoids reading the entire file content into memory. It will download the remote file directly to a local file stream. The handle is then used as the []body. The file producer leverages this fact and can work directly on the work file {{
handle and perform a {{
to the target filename. As Camel knows it's a local work file, it can optimize and use a rename instead of a file copy, as the work file is meant to be deleted anyway. |
Samples
In the sample below we set up Camel to download all the reports from the SMB/CIFS server once every hour (60 min) and store it as files on the local file system.

{tip} h3. Samples In the sample below we set up Camel to download all the reports from the SMB/CIFS server once every hour (60 min) and store it as files on the local file system. {code:java} protected RouteBuilder createRouteBuilder() throws Exception { return new RouteBuilder() { public void configure() throws Exception { // we use a delay of 60 minutes (eg. once pr. hour) we poll the server long delay = 60 * 60 * 1000L; // from the given server we poll (= download) all the files // from the public/reports folder and store this as files // in a local directory. Camel will use the filenames from the server from("smb://foo@myserver.example.com/public/reports?password=secret&delay=" + delay) .to("file://target/test-reports"); } }; } from("smb://foo@myserver.example.com/sharename?password=secret&delay=60000") .to("file://target/test-reports") {code} |

use

the

org.apache.camel.component.file.GenericFileFilter

You

So

you

need

to

depend
...
on

camel-spring
...
if
...
you
...
are
...
using

Maven.

The

reason

is

that

we

leverage

Spring's
...

to
...
do
...
the
...
actual

matching.

The

file

paths

are

matched
...
with
...
the
...
following
...
rules:
?matches one character*matches zero or more characters**matches zero or more directories in a path
The sample below demonstrates how to use it:
| Code Block | ||||
|---|---|---|---|---|
| ||||
- {{?}} matches one character - {{\*}} matches zero or more characters - {{\*\*}} matches zero or more directories in a path The sample below demonstrates how to use it: {code:xml} <camelContext xmlns="http://camel.apache.org/schema/spring"> <template id="camelTemplate"/> <!-- use myFilter as filter to allow setting ANT paths for which files to scan for --> <endpoint id="mySMBEndpoint" uri="smb://foo@myserver.example.com/sharename?password=secret&recursive=true&filter=#myAntFilter"/> <route> <from ref="mySMBEndpoint"/> <to uri="mock:result"/> </route> </camelContext> <!-- we use the AntPathMatcherRemoteFileFilter to use ant paths for includes and exclude --> <bean id="myAntFilter" class="org.apache.camel.component.file.AntPathMatcherGenericFileFilter"> <!-- include any files in the sub folder that has day in the name --> <property name="includes" value="**/subfolder/**/*day*"/> <!-- exclude all files with bad in name or .xml files. Use comma to separate multiple excludes --> <property name="excludes" value="**/*bad*,**/*.xml"/> </bean> {code} {include:Endpoint See Also} - [File2] |
