我正在使用SpringMVC,我正在将数据从Ajax传递到控制器,但是我在控制器中得到了空值,请检查下面的代码
function searchText() { var sendData = { "pName" : "bhanu", "lName" :"prasad" } $.ajax({ type: "POST", url: "/gDirecotry/ajax/searchUserProfiles.htm, async: true, data:sendData, success :function(result) { } }
MyControllerCode
RequestMapping(value="/gDirecotry/ajax/searchUserProfiles.htm",method=RequestMethod.POST) public @ResponseBody String getSearchUserProfiles(HttpServletRequest request) { String pName = request.getParameter("pName"); //here I got null value }
任何人都可以帮助我
嘿享受下面的代码。
Javascript AJAX调用
function searchText() { var search = { "pName" : "bhanu", "lName" :"prasad" } $.ajax({ type: "POST", contentType : 'application/json; charset=utf-8', dataType : 'json', url: "/gDirecotry/ajax/searchUserProfiles.html", data: JSON.stringify(search), // Note it is important success :function(result) { // do what ever you want with data } }); }
弹簧控制器代码
RequestMapping(value="/gDirecotry/ajax/searchUserProfiles.htm",method=RequestMethod.POST) public @ResponseBody String getSearchUserProfiles(@RequestBody Search search, HttpServletRequest request) { String pName = search.getPName(); String lName = search.getLName(); // your logic next }
以下搜索类如下
class Search { private String pName; private String lName; // getter and setters for above variables }
该类的优点是,将来可以根据需要向该类添加更多变量。 例如。 如果要实现排序功能。
