web.xml配置：

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
    classpath:resources/spring/ApplicationContext.xml
        </param-value>
    </context-param>
    <!-- Spring 主控制器Servlet -->
    <servlet>
        <servlet-name>springMVC</servlet-name>

        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:resources/spring/ApplicationContext-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <listener>
