Property value is not access - apache-camel

Question

I am beginner for camel. I have some problem.
We are implementing file transfer system using camel.
I set property from external property file.
But application is not accessed to this property file. We cannot use propertyplaceholder because the value will be changed at runtime.
We implemented it like below.
camelContext.xml :
<bean id="myProperties" class="java.util.Properties"/>
<bean id="propertylist"
class="org.apache.camel.component.properties.PropertiesComponent">
<property name="cache" value="true"/>
<property name="location" value="classpath:camelap.properties"/>
<property name="overrideProperties" ref="myProperties"/>
</bean>
<camelContext id="camelContext-f611cb6c-d516-4346-9adc-5512d327a88d"
trace="false" xmlns="http://camel.apache.org/schema/spring">
<camel:route id="initial_info">
<camel:from id="_initial" uri="direct:sqlParam"/>
<camel:to id="_selectReference" uri="sql:{{sql.referenceInfo}}?
dataSource=dataSource"/>
<camel:process id="_process1" ref="tempBean"/>
<camel:log id="_aaaa" loggingLevel="WARN" message="tttttttt :::
{{test}} ::: ${header.sourceDirectory}"/>
</camel:route>
camelap.properties :
path : target/classes
file.uri=/home/WRK/KR/SND/DAT
test=OLD_VALUE
file.pattern=SLPNPM*,SPLNCC*,SLPNCM*,SLPNPC*

If you want to use the properties component, you need to bind a name with properties, just like this.
<camelContext trace="{{foo.trace}}" xmlns="http://camel.apache.org/schema/spring">
<propertyPlaceholder id="properties" location="org/apache/camel/spring/processor/myprop.properties"/>
<template id="camelTemplate" defaultEndpoint="{{foo.cool}}"/>
<route>
<from uri="direct:start"/>
<setHeader headerName="{{foo.header}}">
<simple>${in.body} World!</simple>
</setHeader>
<to uri="mock:result"/>
</route>
</camelContext>

Not sure if you are using spring boot, there is a simple way to leverage the spring boot properties within Camel Route.
