Answer 1

I followed the answer by @Ryan Hoegg and after a few modifications my answer is as below:

Global Element:

<spring:beans>
    <spring:bean id="LoadFile" name="Bean" class="java.lang.String">
        <spring:constructor-arg>
            <spring:bean id="Test" name="org.springframework.util.FileCopyUtils" class="org.springframework.util.FileCopyUtils" factory-method="copyToByteArray">
                <spring:constructor-arg type="java.io.InputStream" value="classpath:MSG_IDENTIFIER.xml"/>
            </spring:bean>
        </spring:constructor-arg>
    </spring:bean>

</spring:beans>

To Retrieve:

<set-variable variableName="Contents" value="#[app.registry['LoadFile']]" doc:name="Variable"/>

P.S - I placed the file under src/main/resources

You could import the custom configuration file in following way :-

<spring:beans>
    <spring:import resource="domain-A-config.xml" />
    <spring:import resource="domain-B-config.xml" />
    <spring:import resource="admin-config.xml" />
  </spring:beans>

One way to get the contents of a file into a flow variable is to create a spring bean with the contents of the file as described in this Stack Overflow question. Then, you can refer to it using MEL:

<set-variable variableName="niftyData" value="#[app.registry['myBeanName']]" />
