properties - Escape property reference in Spring property file

Question

I want to escape my Spring propeties file in order to get in my bean property: ${ROOTPATH}/relativePath

I have a simple Spring config file that contains:

<context:property-placeholder location="classpath:myprops.properties" />

<bean id="myBean" class="spring.MyBean">
    <property name="myProperty" value="${myproperty}" />
</bean> 

The myprops.properties contains:

myproperty=${ROOTPATH}/relativePath

The above setup returns: Could not resolve placeholder 'ROOTPATH'. I tried a lot of possible syntaxes but was not able to find the right one.

Answer 1

Instead of ${myproperty} use #{'$'}{myproperty}. Simply replace $ with #{'$'}.
