In the<list/>, <set/>,<map/>, and <props/> elements, you set the properties and arguments of the JavaCollection types List, Set,Map, and Properties, respectively .

<bean id="moreComplexObject" class="example.ComplexObject"><!-- results in a setAdminEmails(java.util.Properties) call --><property name="adminEmails"><props><prop key="administrator">administrator@example.org</prop><prop key="support">support@example.org</prop><prop key="development">development@example.org</prop></props></property><!-- results in a setSomeList(java.util.List) call --><property name="someList"><list><value>a list element followed by a reference</value><ref bean="myDataSource" /></list></property><!-- results in a setSomeMap(java.util.Map) call --><property name="someMap"><map><entry key="an entry" value="just some string"/><entry key ="a ref" value-ref="myDataSource"/></map></property><!-- results in a setSomeSet(java.util.Set) call --><property name="someSet"><set><value>just some string</value><ref bean="myDataSource" /></set></property></bean>

The value of a map key or value, or a set value, can also again be any of the following elements:
