newbie question : how to define a bean of type List ?

[cblin]

Hi,

this is surely a stupid question but I do not find its answer in the docs.

How can you define a bean which is a <list> ?

Here is my wished applicationContext :

  <bean id="mylist" class="????">
    <value>elem0</value>
    <value>elem1</value>
  </bean>

  <bean id="test" class="some.class.with.a.list.attribute">
    <property name="alist"><ref local="mylist" /> </property>
  </bean>

  <bean id="test2" class="some.otherclass.with.the.same.list.attribute">
    <property name="alist"><ref local="mylist" /> </property>
  </bean>

The idea is that I have multiple beans inherited from a class having a list attribute, and that every bean uses EXACTLY the same list so, ATM, I am writing a lots of :

  <bean id="test" class="some.class.with.a.list.attribute">
    <property name="alist">
      <list>
        <value>elem0</value>
        <value>elem1</value>
      </list>
  </bean>

  <bean id="test2" class="some.otherclass.with.the.same.list.attribute">
    <property name="alist">
      <list>
        <value>elem0</value>
        <value>elem1</value>
      </list>
  </bean>

  ...

thanks for any help,

regards,
chris

Depend if you use spring 2 or 1.x.

Check this, it covers both versions :

Take a look at the ListFactoryBean.

Some example code

<bean id="myList" class="org.springframework.beans.factory.config.ListFactoryBean">
    <property name="sourceList">
        <list>
            <value>elem0</value>
            <value>elem1</value>        
        </list>
    </property>
</bean>
