jsonp调用示例（前端js+后端java实现）

前端

$.jsonp({

        url: "http://10.12.8.69:8290/dd_SJ/rest/shuntRest/synchronous",

        contentType: "application/x-www-form-urlencoded; charset=utf-8",

        data: {

            type: Ctype,

            mobileNo: MobileNo,

            linkMan: LinkMan,

            contactNumber: ContactNumber,

            problemTypes: ProblemTypes,

            province: Province,

            city: City,

            region: Region,

            fullAddress: FullAddress,

            concreteProblems: ConcreteProblems

        },

        jsonp: "callback",

        callback: "success_jsonpCallback",

        error: function (xOptions, textStatus) {

            // 错误发生时，立即执行

            console.log('exec ERROR');

        },

        success: function (res) {

            console.log('req success:' + res.success);

            if (res.success=="true") {

                alert("提交成功");

            }

        }

    });

后端

//JSONP测试服务端

@RequestMapping(value ="/thirdparty/palmhall/orderTransferToHollyV8", produces={"text/html;charset=UTF-8;","application/json;"})

@ResponseBody

public void orderTransferToHollyV8(HttpServletResponse response,HttpServletRequest request, SheetVo vo)throws UnsupportedEncodingException {

JSONObject returnJson =new JSONObject();

    //String name = new String(vo.getCity().toString().getBytes("ISO-8859-1"), "GBK");

    String city = ParamUtils.getParameter(request, "city");

    //city = new String(city.getBytes("ISO-8859-1"),)

    String  str=new String(vo.getCity().getBytes("ISO-8859-1"),"utf-8");

    PrintWriter pw =null;

    returnJson.put("success", "true");

    try {

pw = response.getWriter();

        //success_jsonpCallback与前台保持一致

        pw.write("success_jsonpCallback" +"(" + returnJson.toString() +")");

        pw.close();

        pw =null;

    }catch (Exception e) {

log.error(e, e);

        returnJson.put("result", "FAIL");

        returnJson.put("message", "系统异常，请稍候再试。");

    }

}
