Ajax json POST和Spring MVC Controller

Question

我有像这样的ajax json POST方法

$.ajax({
    type: 'POST',
    url: "localhost:8080/webeditor/spring/json/", 
    data: JSON.stringify(contents),
    dataType: "json"
});

控制器处理发布请求

JSONPObject json;
BindingResult result = new BeanPropertyBindingResult( json , "MyPresentation" );
@RequestMapping(value="json/", method = RequestMethod.POST)
public void savePresentationInJSON(Presentations presentation,BindingResult result) {
        //do some action

}

但是我收到了这个错误

XMLHttpRequest无法加载localhost:8080/webeditor/spring/json /.仅支持HTTP的跨源请求.

我不确定如何纠正上述错误.

我的最终作品版本

var jsonfile={json:JSON.stringify(contents)};
$.ajax({
    type: 'POST',
    url: "/webeditor/spring/json/", 
    data: jsonfile,
    dataType: "json"
});

AJAX,和

@RequestMapping(value = "/json/", method = RequestMethod.POST)
public void saveNewUsers( @RequestParam ("json") String json)
{
    System.out.println( json );
}
