Ajax调用Java Rest API

Question

I am having ajax problems that I cannot figure out, and need some help... I am using Spring for my REST api and my ajax calls don't seem to work... I have searched the forums and haven't been able to find an answer:

My java Spring api is as follows:

@Controller
@RequestMapping("api")
public class RecentRestController {

    RecentService recentService;

    @Autowired
    public void PersonRestController(RecentService recentService) {
        this.recentService = recentService;
    }

    /**
     * Add recent lake, then get recently viewed lakes and users ordered by timestamp
     * @param handle
     * @return
     */
    @RequestMapping(value = "recent/weather/{auser}/{temp}/{windspeed}/{winddeg}/{laketag}", method = RequestMethod.GET)
    @ResponseBody
    public RecentlyViewedList getRecentlyViewedLakes(@PathVariable String auser, @PathVariable Integer temp, 
            @PathVariable Integer windspeed, @PathVariable Integer winddeg, @PathVariable String laketag) {

        RecentlyViewedList rvl = recentService.getRecentlyViewedWeather(auser, temp, windspeed, winddeg, laketag);
        return rvl;
    }

When I use ajax to call this Java REST from ajax it doesn't seem to work. My ajax call looks as follows from html/php:

new $Ajax.Request('http://localhost:8080/server/api/weahter/lake/' + agruments.auser + '/' + arguments.windspeed +'/' + arguments.winddeg + '/' + arguments.laketag, {
      type : "GET",
       //:url : recenturl,
       //cache : false,
       async : false,
       crossDomain: true,
       dataType : 'jsonp',
       //data: arguments,
       success : function(recent) {


           alert("SUCESS");
            var i=0;

            var lakecount = recent.lake.length;
            var usercount = recent.user.length;

            alert("lakecount:" + lakecount);
            alert("usercount:" + usercount);

       },
       error : function(XMLHttpRequest, textStatus, errorThrown) {
          alert("An error has occurred making the request: " + errorThrown);
       }, 
    });

It never seems to work. It never calls my REST api correct.. What am I doing incorrectly?

Something is wrong with how I calling my REST service..

Any help is greatly appreciated..

Thanks in advance.

Answer 1

As you are checking for a @GET request, the most obvious thing to do is to try to hit the API directly from a browser ( type in your URL field

http://localhost:8080/server/api/weahter/lake/' + agruments.auser + '/' + arguments.windspeed +'/' + arguments.winddeg + '/' + arguments.laketag 

with the parameters resolved ).

Other thing you should be checking is that your context path is 'server' as that is where the URL is pointing.

Also you have and spelling error in the first parameter of the URL: 'agruments' instead of 'arguments'

Answer 2

Yeah, the request has recent in it. What I cannot figure out is that if I build it manualy:

   url : 'http://localhost:8080/server/api/recent/lake/nightstalker/3/3/3/TXFORK'

it works. But when I build it with variables, it does not.
