using values from a properties-file in setHeader-method

[Christoph Burmeister]

hi,

how can I set a header with a value from a properties-file using
spring-xml?
Doing this with the const-tag is no problem, but then the value has to be
directly written in the camel.xml:

<setHeader>
   <const>foobar</const>
</setHeader>

I like to use something like this:

environment.properties:
-----------------------------
header.value=foobar

camel.xml
---------------
<beans>
   <bean id="placeholderConfig"

class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>environment.properties</value>
                <value>another-file.properties</value>
            </list>
        </property>
    </bean>


    <route>
     ...
         <setHeader>
                 ${header.value}
         </setHeader>
      ...
    </route>
</beans>

Is there a solution for camel 2.7 ?

best,
christoph

Does this solve your needs: http://camel.apache.org/constant.html

<from uri="seda:a"/>
<setHeader headerName="theKey">
<constant>theValue</constant>
</setHeader>

Best,
Christian

My guess is that something like this should work:

    <setHeader headerName="myHeader">
            <simple>${properties:key}</simple>
    </setHeader>

Hi,

@Christian: That would mean, I have to hold the value for the header in my
camel.xml and that's not what I need. I need it in a separate file :-/
Thank's anyway.

@Bilgin: That's the way it works :-) Thank you.

For others: you need to define a propertyPlaceholder in the context to use
external properties:


camel.properties
-----------------------
header.value = foobar

camel.xml
---------------

    <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<propertyPlaceholder id="properties" location="camel.properties"/>
                <route>
                      .....
                      <setHeader headerName="foobarHeader">
<simple>${properties:header.value}</simple>
                      </setHeader>
                      <log message="set header >>foobarHeader<< to
value ${properties:header.value}" loggingLevel="INFO" />
                      ...
                </route>
    <camelContext>


best,
christoph

Hi All,

I am trying to set few header's, but does not seem to work.
I guess I am missing something but not able to find that out.
The below logs age not printted in the log file.

<route>
      <from ref="acquireltel2" />
            <setHeader headerName="pathName"><simple>${file:path}</simple></setHeader>
                  <log message="set header pathName to ${file:path}" loggingLevel="INFO"/>
            <setHeader headerName="fileName"><simple>${file:name}</simple></setHeader>
              <log message="set header fileName to ${file:name}" loggingLevel="INFO"/>
        <setHeader headerName="fileType"><constant>ltel2</constant></setHeader>
              <log message="set header fileType to ltel2" loggingLevel="INFO"/>
      <to ref="producerQueue"/>
</route>

Appriciate your help.

Ebe

Put the <log> outside the <setHeader>.

I see something strange here.
If I have the below to routes, the logginf works perfectly.
<route>
        <from ref="acquireltel2" />
                <setHeader headerName="pathName"><simple>${file:path}</simple></setHeader>
                        <log message="set header pathName to ${file:path}" loggingLevel="INFO"/>
                <setHeader headerName="fileName"><simple>${file:name}</simple></setHeader>
                        <log message="set header fileName to ${file:name}" loggingLevel="INFO"/>
                <setHeader headerName="fileType"><constant>ltel2</constant></setHeader>
                        <log message="set header fileType to ltel2" loggingLevel="INFO"/>
                <to ref="producerQueue"/>
</route>
<route>
        <from ref="producerQueue"/>
                <log message="Processing messege out of producerQueue ${file:name}   ${file:path}" loggingLevel="INFO"/>
        <to uri="jms:queue:test_request_2"/>
</route>

But NOT if I have the second route as below. Do not know what difference it makes in the flow.
I am not seeing any of the logs.


<route>
        <from ref="producerQueue"/>
                <log message="Processing messege out of producerQueue" loggingLevel="INFO"/>
                <choice>
                        <when>
                                <simple>${header.fileType} == "ltel2"</simple>
                                <log message="processing ltel2 file type" loggingLevel="INFO" />
                                <threads executorServiceRef="ltel2threadpool1">
                                        <bean ref="ltel2Consumer" method="doConsume" />
                                </threads>
                        </when>
                </choice>
</route>


Also please adive if the above Choice evaluation is correct.
