@ResponseBody不返回格式json错误406

@ResponseBody无法返回forma json，我在浏览器上获得了Etat HTTP 406

我正在使用： jackson-core-asl 1.9.3和ajckson-mapper-asl 1.9.3

Getjson：

 var p = $.getJSON("natureParOperateur.html", {nomOperateur: $("select#nomOperateur").val()}, function(j) {

}

SPRING：

 @RequestMapping(value = "/natureParOperateur.html", method = RequestMethod.GET)
            public @ResponseBody
          List<Nature> natureParOperateur(@RequestParam("nomOperateur") String nomOperateur) {
   List<Nature> listeNatures = metier.consulterNaturesParNomOperateur(nomOperateur);
    return listeNatures ;
            }

我的servelet-context：

问题本质上是Spring不知道哪个转换器转换响应 - 这可以通过发送Accept标头来修复，如果你使用AJAX库调用，你可以使用推荐的方法在这里：Cannot properly set the Accept HTTP header with jQuery

如果您使用浏览器获取，则可以选择使用.json扩展名：

将您的请求映射更改为不具有.html扩展名：

@RequestMapping(value = "/natureParOperateur", method = RequestMethod.GET)
public @ResponseBody  List<Nature> natureParOperateur(@RequestParam("nomOperateur") String nomOperateur) {
   List<Nature> listeNatures = metier.consulterNaturesParNomOperateur(nomOperateur);
   return listeNatures ;
}

然后，像http://othman-pc.com:8080/dsi/natureParOperateur.json?nomOperateur=IAM这样的请求应该在内部将扩展名转换为相应的Accept类型（在这种情况下为application/json
