问题描述
我用json结构退出了Spring MVC中的新功能.有点困惑.
I m quit new in spring mvc with json structure. Little bit cofused.
在我的程序中，我的控制器中有以下请求处理程序
In my program i have following request handler in my controller
@ResponseBody
@RequestMapping(value = "/jsonTable", method = RequestMethod.GET)
public String populateJsonTable(@ModelAttribute("model") Person model) {
DataTables<Person> dt = new DataTables<Person>();
Person person = new Person();
List<Person> personList = person.findMatches(ctxt.getSession(), 1);
dt.setEntityData(personList);
dt.setiTotalDisplayRecords(5);
return JsonUtil.toJson(dt);
}
我如何一起返回视图名称和json数据.这样我就可以将json数据填充到正确的jsp页面.
how can i return view name and json data together. so that i can populate json data to right jsp page.
json数据看起来像我在浏览器中得到的

"Id":4,
"Active":null,
"Date":null,
"Name":null,

],

(更改的代码)
@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);
}
错误: 该请求标识的资源只能根据请求接受"标头()生成特性不可接受的响应.
Error : The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers ().
Jsp页面看起来像这样
Jsp page look likes this
<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>
我仍然封锁任何身体可以帮助我.

推荐答案
将控制器的返回类型更改为ModelAndView.我已经更新了您的代码.请尝试以下操作.
Change your controller return type to ModelAndView. I have updated your code. Try the following.
@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("your jsp page here e.g page/personForm", result);
}
