java的json数据返回写法(基于spring mvc)

            @RequestMapping(value="address_list/SelectKfqPersonInfo",method=RequestMethod.GET) 
            @ResponseBody
             public String SelectKfqPersonInfo(
HttpServletRequest request,
HttpServletResponse response,
@RequestParam("zoneId") Integer zoneid,
@RequestParam("Id") Integer id) throws UnsupportedEncodingException{
response.setContentType("text/json");
response.setCharacterEncoding("UTF-8");//设置响应类型,防止中文乱码
JSONObject jsonObject=new JSONObject();
AddressList addresslist =new AddressList();
addresslist.setZoneid(zoneid);
addresslist.setId(id);
SelectKfqPersonnelIn personinfo=address_listService.SelectKfqPersonInfo(addresslist);
String person=personinfo.getName();
Integer duty=personinfo.getDuty();
String phone=personinfo.getPhone();
String mobile=personinfo.getMobile();
jsonObject.put("person", person);
jsonObject.put("duty", duty);
jsonObject.put("phone", phone);
jsonObject.put("mobile", mobile);
jsonObject.put("zoneid", zoneid);
jsonObject.put("id", id);

String json=jsonObject.toJSONString(jsonObject);//如果返回的是个list,可以将这个list封装到Object中,或者转成JsonArrayList,以object或list或string返回,形式不同,前端js处理方法不一样,下面文章给前端处理方法。

PrintWriter out;
try {
out = response.getWriter();
out.write(json);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
