Send formdata to Spring MVC using JavaScript Ajax

I am using JavaScript in JSP. I can send the formData to Spring Controller with <form action> but I needed to send through Ajax now. I am not using JQuery or AngularJS or any other JS framework.

my Form here is:

<form:form  id="saveAddressForm" modelAttribute="address">
    <tr>
        <td><label>Address1</label></td>
        <td><input type="text" name="addressLine1"></td>
        <td><label>Address2</label></td>
        <td><input type="text" name="addressLine2"></td>
    </tr>
    <tr>
        <td><label>LandMark</label></td>
        <td><input type="text" name="londMark"></td>
        <td><label>City</label></td>
        <td><input type="text" name="city"></td>
    </tr>
    <tr>
        <td><label>Pincode</label></td>
        <td><input  type="number" name="pincode"></td>
        <td></td>
        <td><input type="submit" value="Save Addess" onsubmit="saveAddress()"></td>
    </tr>
</form:form>

JS function:

function saveAddress(){
    var xhttp = new XMLHttpRequest();
    xhttp.onreadystatechange = function() {
    if (xhttp.readyState == 4 && xhttp.status == 200) {
        // On success i need to display a message.
    }
  };
xhttp.open("POST", "add_address.html", true);
xhttp.send();}

Here, my formdata ie.,Address object not including in request. 

@RequestMapping(value = "/add_address", method = RequestMethod.POST)
public String addAddress(@ModelAttribute("address") Address address, Model map)
{

    // Services will be called here.
    return null;
}

I think, I am missing something to add my object to request.

I see couple of posts in SOF, they solved with JQuery or AngularJS. I am not aware of these.

Edit

Thinking how to improve my question. I want "modelAttribute" to send to controller. Not individual param nor through JS frame works.

You can use jquery to easily serialize form data and pass with request.

Here is the modified code with jquery. 

function saveAddress(){
    var xhttp = new XMLHttpRequest();
    var form = document.getElementById('saveAddressForm');
    var data = new FormData(form);
    xhttp.onreadystatechange = function() {
    if (xhttp.readyState == 4 && xhttp.status == 200) {
        // On success i need to display a message.
    }
  };
xhttp.open("POST", "add_address.html", true);
xhttp.send(data);}

What is the problem ?

You need to add the parameters to build the Adress object.
