problem description

background written by others, I didn"t write the interface before I wrote the interface myself and then called it with ajax to get no data. I don"t know what went wrong. I don"t know exactly where to put the js and html files

/ / Please paste the code text below (do not replace the code with pictures)
this is controller

@Controller
@RequestMapping("/some")
public class SomeTestController {

@RequestMapping(value ="/test" )
@ResponseBody
public String getAirportList(HttpServletRequest request) {
    JSONObject json = new JSONObject();
    json.put("name", "jack");
    
    
    return json.toJSONString();
}
}

this is ajax

 $.ajax({
type:"post",
url:"/some/test",

dataType:"json",
success:function (data) {
    alert(data);
},
error:function () {
    alert("error");
}
})

what result do you expect? What is the error message actually seen?

then opening the web page will only pop up error
