            HttpServletResponse arg1) throws Exception {

        ModelAndView modelview= new ModelAndView("HelloPage");
        modelview.addObject("welcomeMessage","Hi there user this is my own written message");

You should use bean tag instead of beans tag in your spring-dispatcher-servlet.xml file. 您应该在spring-dispatcher-servlet.xml文件中使用bean标记而不是beans标记。 

  <bean id="HandlerMapping" class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>

  <bean name="/welcome.html" class="com.rohit.hellocontroller.HelloController"/>

  <bean id="viewResolver" class ="org.springframework.web.servlet.view.InternalResourceViewResolver">
