I want to map all my controller calls to some labels. Is there any way to do so. for example i have my controller request URL like:


i want to add a label "Fetching Username" to this mapping.

First of all, here is my Controller:

@RequestMapping(value = "/esta", method = RequestMethod.POST)
public String handleRequest(HttpServletRequest request) {

    Esta estaobject = new Esta();
    // To test, if the parameters are set
    String user = request.getParameter("user");
    String name = request.getParameter("name");
    String shortname = request.getParameter("shortname");
    String was_admin_string = request.getParameter("was_admin");
    String sap_nr = request.getParameter("sap_nr");
    String etl_string = request.getParameter("etl");

    if (user != null && name != null && shortname != null && was_admin_string != null && sap_nr != null && etl_string != null) {
        some code...

    request.getSession().setAttribute("esta", estaobject);

    return "esta";

When I visit the site, it check with the if-statement, if there are some parameters.
If not, then it should just display my form. Then, when I fill the form, it send it with POST and now there are some parameters and it goes through the if-statement.

My problem is: When I visit the site for the first time, it isn't a POST-request, so I get the error message Request method 'GET' not supported.
But change the form to a GET-request isn't a option for me. It must be POST.

So is there a solution to handle the same controller in POST and GET Requests?

Im working on an app that should have a log in screen so I did a very basic just for testing, but it doesn't works. and I debugged but I still don't get the problem, would you help me. This is the code of the controller, it has a very basic if condition but It doesn't works, I send the variables to the console, because I thought the variables were in blank but I get the variables. so I don't know what to do.

@RequestMapping(value = "ingreso.htm", method = RequestMethod.POST)
  public ModelAndView ingreso(
          @RequestParam("usuario") String usuario,
          @RequestParam("clave") String clave,
          HttpServletRequest request) {

    ModelAndView mv = new ModelAndView();
    String destino;

      if(usuario.toString()=="295325" && clave.toString()=="7512"){
          mv.addObject("usuario", usuario);
          destino = "reservacion";
          destino = "login";
          mv.addObject("error", "usuario invalido :'v");

    return mv;


<form method="post" action="ingreso.htm">
        <label>Numero de cuenta</label>
        <input class="form-control" name="usuario" type="number" max-length="4" required>
        <input class="form-control" name="clave" type="password"  required>
        <div class="form-group">
        <input type="submit" value="Entrar">

I want that the method showEnteredData is executed if the Button is pressed. But it does not execute the function. I thought it should do automaticly. What is the problem? Thanks for your help :=)

@RequestMapping(value = "/articles")
public String showHome ( Model model){
    List<Article> article = (List<Article>) gd.findAll(Article.class);  
    model.addAttribute("articles", article);

    return "articles";

@RequestMapping(value = "/articles", method = RequestMethod.POST)
public String showEnteredData(@RequestParam("dropdownFilmeFilter") String filter, Model model) {

    List<Article> article = (List<Article>) gd.sortByAttribute(Article.class, "price", true);

    if (filter == "aufsteigend"){
        article = (List<Article>) gd.sortByAttribute(Article.class, "price", true);
    model.addAttribute("articles", article);

    return "articles";
