【问题描述】：

@ResponseBody 无法返回格式 json，我在浏览器上得到 Etat HTTP 406

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

获取json：

 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 serverlet 上下文：

标签： json spring maven spring-mvc

【解决方案1】：

问题本质上是 Spring 不知道使用哪个转换器转换响应 - 这可以通过发送 Accept 标头来解决，如果您使用 AJAX 库调用，则可以使用此处推荐的方法： Cannot properly set the Accept HTTP header with jQuery

如果您使用的是浏览器获取，则可以选择使用 .json 扩展名：

将您的请求映射更改为没有 .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适当的接受类型（在这种情况下为 application/json

我无法解决我的问题 :'( 我删除了扩展 html 并且我测试了通过 ajax 发送 Accept 标头我无法从 ResponseBody 生成 formt json
yeeeeeeeeeeeeeeeeeeeeeeeeeeees 谢谢你uuuuuuuuuuuuuuu 我通过在jsp和spring中删除扩展html并将jackson的gggggg jar更改为1.9.3 asl和mapper来解决我的问题非常感谢
