DispatcherServlet 对应的contextConfigLocation 中的xml文件中添加

<context:annotation-config />  
<mvc:annotation-driven />

    <servlet>
        <servlet-name>ibizsys-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <!-- 默认/WEB-INF/[servlet名字]-servlet.xml加载上下文，
                如果配置了contextConfigLocation参数，
                将使用classpath:/ibizsys-dispatcher-servlet.xml加载上下文
            -->
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:/ibizsys-dispatcher-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!-- 拦截匹配的请求，这里所有请求采用名字为ibizsys-dispatcher的DispatcherServlet处理 -->
    <servlet-mapping>
        <servlet-name>ibizsys-dispatcher</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
