public class PlaceholderWithDefaultConfigurer
extends PropertiesPlaceholderConfigurer

PropertyPlaceholderConfigurer that allows to define inline default values.

Example:

 <bean class="org.riotfamily.example.HelloWorld">
     <property name="message" value="${hello.message=Hello World}" />
 </bean>
 

Since Riot 7.0 you can specify null as default value:

 <bean class="org.riotfamily.example.HelloWorld">
     <property name="message" value="${hello.message=}" />
 </bean>
 

Please note the the trailing equals sign. If omitted, the behavior will depend on the setting of the ignoreUnresolvablePlaceholders flag.
