@RequestMapping(value="FileUpload",method=RequestMethod.GET) public String showForm(ModelMap model){ UploadForm form = new UploadForm(); model.addAttribute("FORM", form); return "FileUpload"; }

[code]@RequestMapping(value=“indo”,method=RequestMethod.POST)
public String processForm(@ModelAttribute(value=“FORM”) UploadForm form,BindingResult result, Model model){
if(!result.hasErrors()){
FileOutputStream outputStream = null;
String filePath = System.getProperty(“java.io.tmpdir”) + “/” + form.getFile().getOriginalFilename();
try {
outputStream = new FileOutputStream(new File(filePath));
outputStream.write(form.getFile().getFileItem().get());
outputStream.close();

return “redirect:success”;
} catch (Exception e) {
System.out.println(“Error”);

	}else{

}[/code]

[code]@RequestMapping(value=“success”, method = RequestMethod.GET)
public String blasta(@ModelAttribute(“Filepath”) String filepath, Model model){
Blast sb = new Blast(“blablabla”);
String[] blastIt = sb.blast(“blablabla”, filepath);
String newLine = System.getProperty(“line.separator”);
ArrayList resultado= new ArrayList<>();

    for (int i = 5; i < blastIt.length; i++) {
        if(blastIt[i].startsWith("Lambda")){
            break;
        } else {
        	resultado.add(blastIt[i]);
            System.out.println(blastIt[i]);
        }
        model.addAttribute("RESULTADO", resultado);
                  
    }      
    File f1 = new File(filepath);
    f1.delete();
    return "success";
   
}[/code]

Esses aqui são meus controllers usando o spring mvc 3, tá funcionando direito porem tou com uma duvida em uma coisa aqui, o caminho na barra de endereço fica

http://localhost:8081/Ambase/success?Filepath=caminhoaqui

e eu queria que a url fosse somente http://localhost:8081/Ambase/success
Ele tá passando o atributo na url, teria como eu tirar isso?
