页面端写为：

Js代码

var api = "http://192.168.2.139/WebTest/api/search/getProjectStatusList";var name = $("#firstForm input[name='name']").val();$.ajax({type: 'post',url : api,//async: false,dataType : 'jsonp',jsonpCallback:'callback',data: {'name':name},success : function(json){    //TODO},error : function(XMLHttpRequest,textStatus,errorThrown) {    //TODO}});

var api = "http://192.168.2.139/WebTest/api/search/getProjectStatusList";var name = $("#firstForm input[name='name']").val();$.ajax({type: 'post',url : api,//async: false,dataType : 'jsonp',jsonpCallback:'callback',data: {'name':name},success : function(json){    //TODO},error : function(XMLHttpRequest,textStatus,errorThrown) {    //TODO}});

后端写为：

@RequestMapping(method=RequestMethod.GET,value="getProjectStatusList",produces="text/html;charset=UTF-8")@ResponseBodypublic String getProjectStatusList(HttpServletRequest request, HttpServletResponse response){Map<String,Object> map = new HashMap<String,Object>();try{String callback = request.getParameter("callback");//System.out.println("token:"+request.getHeader("token"));List<String> list = ss.getProjectStatusList();map.put("status", "success");map.put("data", list);ObjectMapper mapper = new ObjectMapper();//这个拼接是重点。。。String result = callback+"("+mapper.writeValueAsString(map)+")";//String result = mapper.writeValueAsString(map);return result;}catch(Exception e){JSONObject jo = new JSONObject();jo.put("status", "fail");jo.put("data", e.getMessage());return jo.toString();}}
