spring mvc传值 html取值

Controller中：

@Controller

@RequestMapping(value="")

public class IndexController {

   @RequestMapping(value = "/trackStationInfo/{trackId}")
    public String getTrackStation(Model model, @PathVariable String trackId){
        model.addAttribute("trackId",trackId);
        return "trackStationInfo";

    }
}

或者

  @RequestMapping(value = "/trackStationInfo")
    public String getTrackStation(Model model, String trackId){
        model.addAttribute("trackId",trackId);
        return "trackStationInfo";
    }

页面中

   
   

如果是第一种controller写法：

ajax中：

    url:"/api/station/getStationByStationName/"+stationName,

网页中打开：localhost:6999/trackStationInfo/{26}

其中26为trackId

  

如果是第二种controller写法：

ajax中：

   url: "/api/equipment/getEquipment/?trackId="+trackId,

网页中打开：localhost:6999/trackStationInfo?trackId=26

其中26为trackId
