  web.xml里配置了上下文监听器了吗

  <!-- 读取上下文参数的监听器类 -->
  <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <servlet>
      <display-name>DispatcherServlet</display-name>
      <servlet-name>DispatcherServlet</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:spring-mvc.xml</param-value>
      </init-param>
      <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
      <servlet-name>DispatcherServlet</servlet-name>
      <url-pattern>/</url-pattern>
  </servlet-mapping>
