spring map bean定义

一般我们知道在property属性里面定义一个无id的map是比较容易的, 但是如何将map定义一个单独的bean, 以便重用, google了一下, 这里给出了说明, 不过有些问题, 没有value那个节点, 不知道是否spring版本的问题, 修改之后, 备注一下.

<bean id="SymbolMap" class="java.util.HashMap">
    <constructor-arg>
       <map>
         <entry>
            <key><value><![CDATA[us;djia]]></value></key>
            <value><![CDATA[us&dji]]></value>
         </entry>
       </map>
    </constructor-arg>
</bean>

还用另外一种形式:

<bean id="emails" class="org.springframework.beans.factory.config.MapFactoryBean">
  <property name="sourceMap">
      <map>
        <entry key="pechorin" value="[e-mail]"/>
        <entry key="raskolnikov" value="[e-mail]"/>
        <entry key="stavrogin" value="[e-mail]"/>
        <entry key="porfiry" value="[e-mail]"/>
      </map>
  </property>
</bean>

     <bean id="fieldMap" class="org.springframework.beans.factory.config.MapFactoryBean">
          <property name="sourceMap">
               <map>
                    <entry key="title" value-ref="obj"></entry>
                    <entry key="reserve_price" value-ref="double"></entry>
                    <entry key="auction_status" value-ref="obj"></entry>
                    <entry key="quantity" value-ref="obj"></entry>
                    <entry key="options" value-ref="obj"></entry>
                    <entry key="spu_id" value-ref="obj"></entry>
                    <entry key="sold_quantity" value-ref="obj"></entry>
                    <entry key="features" value-ref="obj"></entry>
                    <entry key="category" value-ref="obj"></entry>
                    <entry key="user_id" value-ref="obj"></entry>
                    <entry key="auction_id" value-ref="obj"></entry>
                    <entry key="gmt_modified" value-ref="date"></entry>
                    <entry key="pict_url" value-ref="obj"></entry>
                    <entry key="sync_version" value-ref="obj"></entry>
               </map>
          </property>
     </bean>
     <bean id="date" class="java.lang.Class" factory-method="forName">
          <constructor-arg value="java.util.Date"/>
     </bean>
     <bean id="double" class="java.lang.Class" factory-method="forName">
          <constructor-arg value="java.lang.Double"/>
     </bean>
     <bean id="obj" class="java.lang.Class" factory-method="forName">
          <constructor-arg value="java.lang.Object"/>
     </bean>

spring自带的schema util可以。

<util:map id="emails">
    <entry key="pechorin" value="[e-mail]"/>
    <entry key="raskolnikov" value="[e-mail]"/>
    <entry key="stavrogin" value="[e-mail]"/>
    <entry key="porfiry" value="[e-mail]"/>
</util:map>
