How can I receive an object from a form in an action, in order to avoid the getter and setter to receive field to field?

Example in Spring MVC

@RequestMapping(value = "/registro", method = { RequestMethod.POST })
    public String crearUsuario(@ModelAttribute Usuario user,HttpServletRequest req) {
        ModelMap  model = new ModelMap();
        registrarUsuario.crearUsuario(user);
        req.getSession().setAttribute("idUsuario",user.getIdUsuario());
        req.getSession().setAttribute("usuario",user.getNomUsuario());

        return "redirect:/home";
    }

In this case I am receiving a user object, as would be its equivalent in an action of struts2? Thank you very much.

In your struts Action create only one getter and setter for your object, for example User:

Usuario getUsuario(){
  return this.usario;
}

void setUsuario(Usuario usuario){
 this.usuario = usuario;
}

In the jsp, within your form, you can use struts2 tags to access the User's attributes:

<s:form ...>
    <s:textfield name="usuario.nombre" label=...>
    <s:textfiled name="usuario.apellido" label=...>
<s:form/>

And the User class is the one that has the getters and setters for each attribute:

public class Usuario {
  private String nombre;
  private String apellido;

  String getNombre(){return nombre;}
  String getApellido(){return apellido;}
  void setNombre(String nombre){this.nombre = nombre;}
  void setApellido(String apellido){this.apellido = apellido;}
}
