java - Ajax json POST 和 Spring MVC Controller

Question

我有这样的 ajax json POST 方法

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

处理发布请求的 Controller

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

}

但是我得到了这个错误

XMLHttpRequest cannot load localhost:8080/webeditor/spring/json/. Cross origin requests are only supported for HTTP.

我不确定如何更正上述错误。

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 );
}
