Before upgrading to Spring 3 I had this
in my applicationContext.xml file:
<bean class="com.northgateis.pole.ws.PolePayloadValidatingInterceptor">
<property name="validateRequest" value="${validateRequest}" />
<property name="validateResponse" value="${validateResponse}" />
</bean>
where ${validateRequest) and ${validateRequest) refer to properties that may or may not be defined
in my properties file.
In Spring 2, if these proeprties were not present
in the properties file the setters on the bean were not called and so the defaults hard-coded
in PolePayloadValidatingInterceptor were used.
After upgrading to Spring 3, it seems the behaviour is different: If the properties are not present
in the properties file I get the following exception:
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'annotationMapping' defined
in class path resource [com/northgateis/pole/ws/applicationContext-ws.xml]: Could not resolve placeholder 'validateRequest'

I tried dabbling with Spring EL but the following doesn't seem to work:
<bean class="com.northgateis.pole.ws.PolePayloadValidatingInterceptor">
<property name="validateRequest" value="${validateRequest?:true}" />
<property name="validateResponse" value="${validateResponse?:false}" />
</bean>
The value after the Elvis operator is always used, even when the properties are defined
in the proeprties file. Interesting that the syntax is accepted.
Any suggestions?
