Question

我在使用Spring MVC的ajax时遇到了一些问题。我想使用ajax刷新一页（并从控制器获取一页）。所以我正在做的事情。

$.ajax({                                       
  url : '/getCartProducts',
  type : 'GET',
  async: true,
  data : {},
  success : function(data) {  
    //data shoud be rendered jsp with model from the controller  
  },
  error: function (jqXHR, textStatus, errorThrown) {
    alert(jqXHR + " : " + textStatus + " : " + errorThrown); 
  }
})`

此功能应该从控制器给我视图页面。这是我的控制器。

@RequestMapping(value = "/getCartProducts", method = RequestMethod.GET)
@ResponseBody String ajaxGetProdCart(HttpServletRequest request) {
    LOG.trace("We are in the controller");      
    return "cart"; //this is jsp page
}

在没有@ResponseBody的情况下尝试这样做，但它无法正常工作。它提醒我错误：Not found

您的cart.jsp必须是内页文件夹。您必须删除@ResponseBody注释
