i can't figure out mistake in code:

<form class="form-horizontal" action="#" th:action="@{/teacher/teacherprofileupdation}" th:object="${teacherprofiledetailslist}"                          id="saveteacherform" method="post" > <br /> <div class="row">      <div class="col-lg-14 col-md-12">         <br />         <h5 style="margin-left: 15%;">personal details</h5>         <hr />         <div class="form-group">             <label class="col-sm-3 control-label">name</label>             <div class="col-md-3 col-sm-4 col-xs-4">                 <input placeholder="teacher first name" id="txtteacherfname" th:field="*{firstname}" type="text" class="form-control" />             </div>             <div class="col-md-3 col-sm-4 col-xs-4">                 <input placeholder="teacher middle name" id="txtteachermname" th:field="*{middlename}" type="text" class="form-control" />             </div>             <div class="col-md-3 col-sm-4 col-xs-4">                 <input placeholder="teacher last name" id="txtteacherlname" th:field="*{lastname}" type="text" class="form-control" />             </div>         </div>      </div>     <div class="col-lg-14 col-md-12">         <div class="form-actions">             <input type="hidden" id="hdnstudentbyidinschooladmin" value="0" />              <input type="button" class="btn btn-info pull-right" id="btnupdateteacherprofile" value="save" />         </div>     </div> </div> 

js:

saveteacherprofile :function(){     $("#saveteacherform").ajaxform({         success : function(status) {              alert("success");         },     }).submit(); } 

controller:

@requestmapping(value = "/updateteacherprofile", method = requestmethod.post)     public string updateteacherprofile( teacherprofiledetails teacherprofiledetails){          system.out.println("-----------"+teacherprofiledetails.getfirstname()+"-------------");         system.out.println("-----------"+teacherprofiledetails.getlastname()+"-------------");         system.out.println("-----------"+teacherprofiledetails.getmiddlename()+"-------------");          return "success";     } 

you posting form, spring controller not configured accept post requests. try in server-side controller class page:

@requestmapping(..., method = { requestmethod.get, requestmethod.post }, ...) public void mycontrollermethod() {
