不支持发布

Question

I am validating a form using jquery validation plugin. On success of validation, ajax call is inserting data in db. But here it is showing post not supported.

$("#evaluatorForm").validate({
// Specify the validation rules
rules: {
    employeeId: "required",
    name: "required",
    lastname: "required",
    email: {
        required: true,
        email: true
    },
    mobile:"required",
    bg:"required",
    bu:"required",

// Specify the validation error messages
messages: {
    name: "Please enter your first name",
    lastname: "Please enter your last name",
    email: "Please enter a valid email address",
},

submitHandler: function(form) {
    $.fn.serializeObject = function() {
        var o = {};
        var a = this.serializeArray();
        $.each(a, function() {
            if (o[this.name] !== undefined) {
                if (!o[this.name].push) {
                    o[this.name] = [ o[this.name] ];
                }
                o[this.name].push(this.value || '');
            } else {
                o[this.name] = this.value || '';
            }
        });
        return o;
    };

    var evdata = JSON.stringify($('#evaluatorForm').serializeObject());
    $.ajax({
        type : 'POST',
        url : '/nhp/rest/evaluator/insertEvaluator',
        contentType : 'application/json',
        data : evdata,
        success : function() {
            alert("Added Successfully");
            $('#evaluatorForm').trigger("reset");

        },
    });

}

}

<form role="form" id="evaluatorForm" method="POST" >
    <fieldset>
        <div class="form-group">
            <input class="form-control" placeholder="Employe Id"

        <div class="form-group">

        <div class="checkbox">

                value="5">ME

        <input  type="submit" value="submit" id="btn" >  <input
            name="cancel" type="button" value="cancel" onclick="redirect()">
    </fieldset>
</form>

@Path("/insertEvaluator")
@POST
@Consumes(value="application/json")
public String addEvaluator(AppUser evdata) {
    Set<Role> roles= new HashSet<Role>();
 try {

     if(evdata.getMe()!=null){
    Role role=roleService.findById(evdata.getMe());
    roles.add(role);
     }
     if(evdata.getTe()!=null){
         Role role2=roleService.findById(evdata.getTe());
            roles.add(role2);
    }
    evdata.setRoles(roles);
    evaluatorService.create(evdata);


} catch (BusinessException e1) {
    e1.printStackTrace();
}

    return  "success";
}

When I click on the submit button it is showing that post is not supported.
