[FIXED] Populate Spring Bean with the return value of a function

Issue

I want to populate a value of my spring bean with the return value of a method. Is there any way I can do this?

<bean id="JmsTemplate" class="org.springframework.jms.core.JmsTemplate">
    <property name="defaultDestinationName"
            value="#Value#returned#by#method" />

I already have a bean of the class which has the method in my application context.

 <bean id=xyz class=path.to.xyz>    
</bean>

Please note that the value that I want to inject is not a variable, but return value of a method.

Solution

You can use factory-bean and factory-method:

<bean id="JmsTemplate" class="org.springframework.jms.core.JmsTemplate">
  <property name="defaultDestinationName">
    <bean factory-bean="xyz" factory-method="methodName" />
  </property>
</bean>

If the method you want to call takes parameters you can pass them in using constructor-arg

<bean factory-bean="xyz" factory-method="methodName">
  <constructor-arg index="0" value="firstParameter" />
  <constructor-arg index="1" ref="someOtherBean" />
</bean>
