Servlet recover Object

Question

It is possible to recover populated object in requestParameter?

Type coming from Javascript?

req.getParameter("objeto");

I have the object Person who possesses

Name

Telephone

in Javascript I send

var obj = {nome: 'Carlos', telefone: '929999999'}

How to recover this populated object in Servlet instead of String

Obj obj = req.getParameter("obj");

Answer 1

According to your description, you must be sending this object via AJAX.

var obj = {nome: 'Carlos', telefone: '929999999'}
$.ajax("url", {
  data: obj,
  method: "POST"
  success:function(data){
          console.log(data);
  }
}

In your Rvlet, just pick up this object through the method getParameter() available in the object HttpServletRequest.

Would something like this

doPost(HttpServletRequest request, HttpServletResponse response) {
  String nome = request.getParameter("nome");
  String telefone = request.getParameter("telefone");

  response.getWriter().write("Nome submetido foi: " + nome + "\n Telefone submetido foi: " + telefone);
}

I hope I helped. Any doubt post in the comments.
