我正在使用带有 JSP 和 jqGrid 的 Spring，并尝试将 JSON 数据发布到我的服务器。

当我转到 URL 时，GET 成功加载了 JSP： http://localhost:8080/sportsSpring/sport-management/sport/

我的 POST 成功保存到数据库，但之后无法重新加载 JSP，但出现异常“无法解析名称为 'SpringApp' 的 servlet 中名称为 'sport' 的视图”。

SpringApp-servlet.xml：

我的运动控制器：

@RequestMapping(method=RequestMethod.GET, value="/sport")
public ModelAndView getSportList() throws NumberFormatException, SQLException, JSONException
{
    sportDao = getSportDao();   
    List<SportBean> sportBeanList = sportDao.getSports();
    JSONArray sportJsonArray = convertToJson(sportBeanList);

    return new ModelAndView("sport", "sports", sportJsonArray);
}

@RequestMapping(method=RequestMethod.POST, consumes="application/json", value="/sport")
public ModelAndView addSport(@RequestBody String body) throws SQLException, JSONException
{
    SportBean sportBean = convertToBean(body, true);

    sportDao = getSportDao();
    sportDao.saveSport(sportBean);

    return new ModelAndView("sport");
}

任何帮助，将不胜感激，

谢谢

两种解决方案：

  • 删除这个：<property name="prefix" value="/"/>
  • 或尝试查看路径的实际前缀，例如 JSP 页面的 WEB-INF 文件夹，例如 <property name="prefix" value="WEB-INF/views/"/>
