Many thanks Claus,
Based on the link provided and feedback received from Costin Leau, here is
what I have done to resolve the issue :
To work with the following uri :
file://d:/temp/data/?move=d:/temp/done/${file.name}
in your camel route and define it in a property file,
here is what you have to do
*Step 1 : Create
org.springframework.beans.factory.config.PropertyPlaceholderConfigurer bean
*
Define a PropertyPlaceHolder (using another prefix/suffix delimiter) to
avoid conflict between your camel variable and Spring property
<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="placeholderPrefix" value="#{"/> (1)
<property name="placeholderSuffix" value="}" /> (2)
<property name="location"
value="classpath:META-INF/spring/org.apache.camel.example.reportincident.routing.properties"
/> (2)
</bean>
(1) : Define a different prefix instead of ${ which is the value by default
and used as variab
(2) : Define the value of the suffix. In this case, this is the same as the
default value
*Step 2 : Create org.apache.camel.example.reportincident.routing.properties*
Create the following file :
org.apache.camel.example.reportincident.routing.properties and put it in
your classpath. If you plan to deploy your camel route under Apache
ServiceMix Kernel --> Apache Karaf, add this file in the META-INF/spring
directory by example
Add the following property :
uriFile=file://d:/temp/data/?move=d:/temp/done/${file.name}
*Step 3 : Create an endpoint in your Camel Spring DSL file*
Create a camel endpoint for the uri that you would like to use
<camel:endpoint id="fileEndpoint" uri="#{uriFile}"/> (1)
(1) As you can see, we use as a Spring variable reference the syntax #{} so
spring will retrieve the value from the variable declared in the file
*Step 4 : Adapt your route*
Define the uri of your route like this :
<camel:from ref="fileEndpoint" />
