[Springframework-developer] PropertyPathFactoryBean

[<jue...@we...>]

I've just added a PropertyPathFactoryBean, following this suggestion:

http://opensource.atlassian.com/projects/spring/browse/SPR-343


Usage examples:

 // target bean to be referenced by name
 <bean id=3D"tb" class=3D"org.springframework.beans.TestBean" =
singleton=3D"false">
   <property name=3D"age"><value>10</value></property>
   <property name=3D"spouse">
     <bean class=3D"org.springframework.beans.TestBean">
       <property name=3D"age"><value>11</value></property>
     </bean>
   </property>
 </bean>

 // will result in 12, which is the value of property 'age' of the inner =
bean
 <bean id=3D"propertyPath1" =
class=3D"org.springframework.beans.factory.config.PropertyPathFactoryBean=
">
   <property name=3D"targetObject">
     <bean class=3D"org.springframework.beans.TestBean">
       <property name=3D"age"><value>12</value></property>
     </bean>
   </property>
   <property name=3D"propertyPath"><value>age</value></property>
 </bean>

 // will result in 11, which is the value of property 'spouse.age' of =
bean 'tb'
 <bean id=3D"propertyPath2" =
class=3D"org.springframework.beans.factory.config.PropertyPathFactoryBean=
">
   <property name=3D"targetBeanName"><value>tb</value></property>
   <property name=3D"propertyPath"><value>spouse.age</value></property>
 </bean>

 // will result in 10, which is the value of property 'age' of bean 'tb'
 <bean id=3D"tb.age" =
class=3D"org.springframework.beans.factory.config.PropertyPathFactoryBean=
"/>


The last one, interpreting the bean name as 'beanName.property' pattern, =
is quite concise...
