@ResponseBody无法返回格式json错误406

@ResponseBody无法返回格式json，并且我在浏览器上收到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) {

}

春天：

 @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上下文：

问题本质上是Spring不知道使用哪个转换器来转换响应-可以通过发送Accept标头来解决此问题，如果您使用AJAX库进行调用，则可以使用此处推荐的方法：无法正确设置Accept HTTP jQuery标头

如果您使用的是浏览器get，则可以选择使用.json扩展名：

将您的requestmapping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，像这样的请求http://othman-pc.com:8080/dsi/natureParOperateur.json?nomOperateur=IAM应该在内部将扩展名转换为适当的Accept类型（在这种情况下，application/json
