Could not resolve placeholder in string value

by

In your configuration you have 2 PropertySourcesPlaceholderConfigurer instances.

applicationContext.xml

<bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer">
    <property name="environment">
        <bean class="org.springframework.web.context.support.StandardServletEnvironment"/>
    </property>
</bean>

infraContext.xml

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

By default a PlaceholderConfigurer is going to fail-fast, so if a placeholder cannot be resolved it will throw an exception. The instance from the applicationContext.xml file has no properties and as such will fail on all placeholders.

Solution: Remove the one from applicationContext.xml as it doesn’t add anything it only breaks things.
