spring mvc jsonp调用示例
服务端代码:主要是返回的时候,返回值要用callback包装一下
/** * JSONP调用 * * @param request * @return */ @RequestMapping("/remote/jsonp") public void remoteJsonp(HttpServletRequest request, HttpServletResponse response) throws IOException { String jsonpCallback = request.getParameter("jsonpCallback"); String data=request.getParameter("data"); //todo something ActionResultEntity result = new ActionResultEntity(); //设置返回值 String returnValue = jsonpCallback + "(" + StringUtil.toJsonString(result) + ")"; response.getWriter().write(returnValue); }
js调用代码:
$.ajax({ async: false, type: "post", url:"http://localhost:8080/main/remote/jsonp", data: { data: "test" }, dataType: "jsonp", jsonp: "jsonpCallback", success: function (successJson) { }, error: function (errorJson,text,message) { } });
