HTTP Status 500 - Could not resolve view with name 'phones' in servlet with name 'dynamic-velocity'

我给ModelAndView的视图名称为myphone， 为啥报错说我的视图名称是phones呢？

方法：

@RequestMapping(value="/phones")
public ModelAndView showPhones() {
    log.info("showPhones.");
    Map  m = new HashMap();
    m.put("phone1", "huawei");
    m.put("phone2", "apple");
    return new ModelAndView("myphone", m);
             
}

web.xml：

 
        dynamic-velocity
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            /WEB-INF/servlet.xml
        
        1
    
        
        dynamic-velocity  
        /  
      

servlet.xml
