Spring 2.0中集合对象注入的复用

如果一个集合对象不光光是注入到一个对象中，那我们需要考虑此集合对象设置ID

List

 

<bean id="mails" class="org.springframework.beans.factory.config.ListFactoryBean">
    <property name="sourceList">
        <value>data1</value> 
        <value>data2</value>
    <property>
</bean>

Map

 

<bean id="mails" class="org.springframework.beans.factory.config.MapFactoryBean">
    <property name="sourceMap">
       <map>
             <entry key="data1" value="data1"/>
             <entry key="data2" value="data2"/>
       </map>
    <property>
</bean>

 Set

 

<bean id="mails" class="org.springframework.beans.factory.config.SetFactoryBean">
    <property name="sourceSet">
       <set>
        <value>data1</value> 
        <value>data2</value> 
       </set>
    <property>
</bean>

 

properties

 

<bean id="mails" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
   <props>
       <prop key="somekey">somekey</prop>
       <prop key="anykey">anykey</prop>
   </props>
</bean>

<!---或者使用location属性->
<property name="localtion">
   <value>src/config/config.properties</value>
</property>
