Configuration problem: Duplicate <http> element detected

web.xml里配了：

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
          /WEB-INF/spring-context/applicationContext.xml,
          /WEB-INF/spring-context/applicationContext_action.xml,
          /WEB-INF/spring-context/applicationContext_dao.xml,
          /WEB-INF/spring-context/applicationContext_service.xml,
          /WEB-INF/spring-context/applicationContext_security.xml,
          </param-value>
    </context-param>

然后在applicationContext.xml 又配了：

<!--    <import resource="applicationContext_dao.xml" />-->
<!--    <import resource="applicationContext_service.xml" />-->
<!--    <import resource="applicationContext_action.xml" />-->

<!--    <import resource="applicationContext_security.xml" />-->

重复了
