How to use Spring to get the value of an Enum

<bean id="xyz" class="com.abc" >
  <property name="name">
    <bean         
            class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean">
        <property name="staticField" value="com.abc.staticname" />
     </bean>
   </property>
</bean>

This is the way previously I used to set the name of class com.abc. Now, the names should come from another enum. How do I access the enum value to set the name property of my class com.abc?

I don't see why you can't keep on using FieldRetrievingFactoryBean, that's what it's for.

It's a little bit easier to use than your example suggests, though. Also, there's the easier schema-based syntax which does the same thing, <util:constant>.

Both approaches are documented (and compared) here.

(Remember that enum values are just static fields on the enum class)

You can just use the enum name as the value, and Spring will automatically detect that it's a static field of the enum type and use it. So for example, if you have an enum com.mycompany.MyEnum with values SOMEVAL, ANOTHERVAL, you can use :

<property name="myEnumProperty" value="SOMEVAL" />

This will allow you to avoid FieldRetrievingFactoryBean and <util:constant> altogether.
