@ResponseBody不返回格式JSON错误406

Question

@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) {
}

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servlet-context：

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我通过此URL进行浏览器：

Answer 1

这个问题本质上是春季不知道要使用哪个转换器转换响应 - 可以通过发送Accept标头来修复，如果您使用AJAX库调用，则可以使用此处推荐的方法：无法正确设置使用JQuery

的Accept HTTP标头

如果您使用的是浏览器获取，则可以使用.json扩展名：

更改您的请求示意图，以没有.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 ;
}

然后像这样的请求http://othman-pc.com:8080/dsi/natureparoperateur.json?nomoperateRiTUR=iam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，application/json
