  web.xml里边没有配置<context>标签及监听器，
  servelt初始化方法init()里边也要加上context初始化的代码
  web.xml里边加上
      <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/classes/applicationContext.xml</param-value>
      </context-param>
  Servlet的初始化方法init()里加上
  
         ServletContext servletContext = this.getServletContext();
         applicationContext = WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);
  别忘引入相应的jar包
