properties components is used per camel context.
I'm afraid you have to define it inside of the camel context if you have
multiple camelContext to use.

Hi,
I'm using Camel 2.7.2, and I have a Spring XML file with multiple Camel
Contexts defined. To expose the properties defined in an external file to
the camel contexts, we have the following lines in the XML:
<bean id="properties"
class="org.apache.camel.component.properties.PropertiesComponent">
<property name="location" value="file:///location/to/file.properties" />
</bean>
We can then use the syntax {{my.property}} in multiple camelContext
definitions in the same file, for example in from:
<camel:from
uri="activemq:name.of.queue?selector=myHeaderProperty='{{my.property}}'" />
However when using Simple, the use of {{ }} for properties does not work, we
must use ${properties:my.property}:
<camel:simple>${properties:my.property} == 'true'</camel:simple>
We must also add the following line to load the properties again for this
camelContext:
<camel:propertyPlaceholder id="properties2"
location="file:///location/to/file.properties"/>
Otherwise it does not work as it doesn't seem to use the bean "properties"
defined elsewhere outside of the camelContext.
My question is, is there a better way of doing this? At the moment, I have
to add a reference to my properties file three times: once for Spring, once
for Camel and once again in the camelContext using camel:simple.
Thanks for any tips!
