我的请求处理程序看起来像这样

@ResponseBody
    @RequestMapping(value = "/jsonTable", method = RequestMethod.GET)
    public ModelAndView populateJsonTable(@ModelAttribute("model") Person model) {
       DataTables<Person> dt = new DataTables<Person>();
       Map<String, Object> result = new HashMap<String, Object>();
       Person person = new Person();
       List<Person> personList = person.findMatches(ctxt.getSession(), 1);
       dt.setEntityData(personList);
       dt.setiTotalDisplayRecords(5);
       result.put("personList", JsonUtil.toJson(dt));
       return new ModelAndView("TeamViewer", result);
    }

Jsp页面是这样的

<head>
    <meta http-equiv="Content-Type" content="application/json; charset=windows-1252">
    <title>JSP Page</title>
    <c:set var="baseURL" value="${pageContext.request.contextPath}"/>
    <link href="${baseURL}/css/jquery-ui-1.8.16.custom.css" rel="stylesheet" type="text/css" />
    <link href="${baseURL}/css/jtable_green.css" rel="stylesheet" type="text/css" />

    <script src="${baseURL}/js/jquery-1.6.min.js" type="text/javascript"></script>
    <script src="${baseURL}/js/jquery-ui-1.8.16.custom.min.js" type="text/javascript"></script>

    <script src="${baseURL}/js/jquery.jtable.js" type="text/javascript"></script>
    <script src="${baseURL}/js/json2.js" type="text/javascript"></script>
</head>

When i hit the ("http://localhost:8080/sample/view/jsonTable") url the its show the following error.

错误：此请求标识的资源只能生成具有根据请求“接受”标头（）不可接受的特征的响应。

任何人都可以说出这段代码有什么问题。

我想用 Json 制作一个数据网格。所以我的想法是从数据库中获取数据作为 Java 模型，然后将其转换为 json 形式。然后将其提供给浏览器。为此，我粘贴了更多 TeamViewer。jsp。或者，如果您可以在其他链接中将 java 数据转换为 json 形式，然后将其呈现为 jsp。然后请分享。

我不是 100% 确定您要做什么，但 @ResponseBody 似乎是问题所在。这个注解告诉 Spring 序列化方法返回的对象并发送给客户端。如果您要返回 ModelAndView，您可能希望将名为 TeamViewer 的渲染视图发送到客户端。简而言之，删除@ResponseBody。
