傳JSON對象
前端
function test () { var param = {username : "yitop"}; $.ajax({ timeout : 20000, type : "POST", dataType : "JSON", url : "/user/userRole.htm", data : param, success : function(data){ alert(data); } //注意：這里不能加下面這行，否則數據會傳不到后台 //contentType:'application/json;charset=UTF-8', }); }后端
Controller:
@RequestMapping(value = "userRole", method = RequestMethod.POST) @ResponseBody public List<Role> selectRoles(String username) throws WebTransException { /* 邏輯代碼 */ }傳JSON字符串+@RequestBody接收
前端
function icheckDelete(url){ var parms = { list : array //這是個數組 }; $.ajax({ dataType: "JSON", contentType:'application/json;charset=UTF-8',//關鍵是要加上這行 traditional:true,//這使json格式的字符不會被轉碼 data: JSON.stringify(parms), type: "DELETE", timeout: 20000, url: url, success : function () { alert("刪除成功！"); }, error : function (data){ alert(data.responseText); } }); }后端
Controller:
@RequestMapping(value = "deleteList", method = RequestMethod.DELETE) @ResponseBody public String delete(@RequestBody DeleteListRequest request) throws WebTransException{ /* 邏輯代碼 */ return "success"; }DeleteListRequest:
/** * @author fengzp * @date 16/12/15下午6:08 * @email fengzp@gzyitop.com * @company 廣州易站通計算機科技有限公司 */ public class DeleteListRequest { List<Map<String, String>> list = new ArrayList<>(); public DeleteListRequest() { } public List<Map<String, String>> getList() { return list; } public void setList(List<Map<String, String>> list) { this.list = list; } }
