我收到“此请求标识的资源只能生成具有根据请求“接受”标头不可接受的特征的响应。” （http 状态 406）尝试从 url 获取 item_id 参数时出错，如下所示：
http://localhost:8080/products/edit_item.html?item_id=3
然后我将获取 item_id 并从数据库中获取单个项目数据。我正在使用 Spring 3.2.4 Tomcat 7 和 eclipse 开普勒。我的控制器方法是：
@RequestMapping(value="edit_item",method=RequestMethod.GET, params="item_id")
public @ResponseBody ModelAndView editItem(@RequestParam(value="item_id") int item_id)
{
//do things with item_id
}
我在网上搜索并看到了有关 json 的问题。我的问题很简单，我只需要从 url 获取单个值。我是春天的新手，也许这对你来说很容易，但我做不到。
而配置文件spring-servlet.xml为：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

这是我的堆栈跟踪：
