使用DTO绑定多个动态创建的字段的相同属性名称

您可以在js中更改您的Submitform函数

$('#submitForm').submit(function(e) { var frm = $('#submitForm'); e.preventDefault(); var data = {}; var dt=[]; var newdt = {}; var Form = this; $.each(this, function(i, v) {     var input = $(v);     if(data.hasOwnProperty("fkcl")) //mapped all dropdown values to fkcl and fkdiv inorder to use `TestDto` variables         {         if(data.hasOwnProperty("fkdiv"))  {  dt.push(data);  data={};  }         }     data[input.attr("name")] = input.val();     delete data["undefined"]; }); newdt['list']=dt; alert(JSON.stringify(newdt)); $.ajax({      async : false,     global : false,      contentType : 'application/json; charset=utf-8',     type : 'post',     url : frm.attr('action'),     data: JSON.stringify(newdt),     success : function(callback) {         window.location.reload();     },     error : function() {         $(this).html("Error!");     }  });

@Controller

@RequestMapping(value = "/save", method = RequestMethod.POST)    public void save(@RequestBody ClassDes testprof) {       for (TestDto t : testprof.getList()) {        serv.save(t);    }        return new "redirect:/testing";    }
