Inserting list inside array

Summary

• Using class ListFactoryBean enable developer to use collection but requires some extra tags making code difficult.
• An easy way to use util schema and tags inside spring xml configuration.
• As the name suggests, the util schema deals with common utility configuration issue such as configuring collections.
• The only change is that we have to change our xml schema a bit.
• list-class attribute of <util:list> tag is used to explicitly control the exact type of List that will be instantiated & populated via using this attribute.

Syntax 1 (util schema)

`

<property name=“…">
    <util:list id=“…”>
        <value>…</value>
        <value>…</value>
        <value>…</value>
    </util:list >
</property>

`

Syntax 2 (util ListFactory bean)

`

<bean class="org.springframework.beans.factory.config.ListFactoryBean">
    <property name="targetListClass">
        <value>java.util.LinkedList</value>
    </property>
    <property name="sourceList"> 
        <list>
	        <value>...</value>
	        <value>...</value>
	        <value>...</value>
        </list>
    </property>
</bean>

• Note - list-class attribute of <util:list> tag is used to explicitly control the exact type of List that will be instantiated & populated via using this attribute.
