Args with Spring MVC

Question

I need help to pars args in a method inside my controller.

i have a form for sending my parameter to function

    <form method="post" action="/">
<input type="text" id="query" placeholder="file to search ...">
<input type="submit" id="submit" value="fetch!">
    </form>

and in my controller :

@RestController
public class mainController {

    @RequestMapping(value = "/index", method = RequestMethod.POST)
    public String index(Model model) throws IOException, GeneralSecurityException {
        DriveQuickstart drive = new DriveQuickstart("c:/temp/credentials.json");
        model.addAttribute("query");
        String res = drive.checkFile("query");

        return res;

the query is a string send via the form. and return res in the same view. Do you have any tips?

thanks you very mutch

In Spring MVC It will be like this:

@Controller
public class mainController {

@PostMapping( "/index")
public String index(@ModelAttribute FormDataObjectClass object) throws IOException, GeneralSecurityException {
    DriveQuickstart drive = new DriveQuickstart("c:/temp/credentials.json");

    //model.addAttribute("query");
    String name = object.getName();
    String address = object.getAddress();
    String res = drive.checkFile("query");

    return res;
}

Here no need of passing Model as argument as we need a custom Object(FormDataObjectClass) to be used. Create a class FormDataObjectClass as per you data in HTML form/JQuery post method
