The reference to entity "characterEncoding" must end with the ';' delimiter.

问题描述：
在做spring注入的时候，
<bean id="storageYKT" class="com.talkweb.ecard.storage.action.StorageYKTMonitor" >
          <property name="url" value="http://116.55.248.117:8090/HelloWorldService/services/HW?useUnicode=true&characterEncoding=utf8"/>  
          <property name="nameSpaceUri" value=""/>
</bean>
报The reference to entity "characterEncoding" must end with the ';' delimiter错误。

解决方案：
把http://116.55.248.117:8090/HelloWorldService/services/HW?useUnicode=true&characterEncoding=utf8改成http://116.55.248.117:8090/HelloWorldService/services/HW?useUnicode=true&amp;characterEncoding=utf8即可。
