Models

We use the base.jar library found in Base

     public Administrateur() {
         this.setDatabaseName("contenu");
     }

     public Administrateur(Object id, Object personne_id, Object username, Object password) {
         this.setDatabaseName("contenu");
         this.id = String.valueOf(id);
         this.personne_id = String.valueOf(personne_id);
         this.username = String.valueOf(username);
         this.password = String.valueOf(password);
     }

     public Administrateur(Object personne_id, Object username, Object password) {
         this.setDatabaseName("contenu");
         this.personne_id = String.valueOf(personne_id);
         this.username = String.valueOf(username);
         this.password = String.valueOf(password);
     }

Services

    public class AdministrateurService {
    private Administrateur administrateur = new Administrateur();

    public AdministrateurService() {

    }

    public void setAdministrateur(Administrateur administrateur) {
        this.administrateur = administrateur ;
    }

    public int login() {
        return this.administrateur.login() ;
    }
}

Controller

- All class controller is annoted with  @ClassAnnotation(className = "the model")
- All method in the controller is annoted with @MethodAnnotation.urlMethod(className = "the model", method = "the method name", url ="the url")
- The controller names must be the model name + "Controller

 private final AdministrateurService administrateurService = new AdministrateurService();
 private Administrateur administrateur = new Administrateur();
 private String page = "";

 public AdministrateurController() {

 }

 public void setAdministrateur(Administrateur administrateur) {
     this.administrateur = administrateur;
 }

 public void setPage(String page) {
     this.page = page ;
 }

 @MethodAnnotation.urlMethod(className = "Administrateur", method = "Login", url = "LoginPage.do")
 public ModelView Login() {
     ModelView retour = new ModelView();
     HashMap<String, List> hash = new HashMap<>();
     this.setPage("Login");
     retour.setHash(hash);
     retour.setPage(this.page);
     return retour;
 }

FrontController

- For downloading a file you , you need to create the basecontroller class which is a daughter class of frontcontroller and the class is annotated by @MultipartConfig(filesizethreshold = 1024*1024, maxfilesize = 1024*1024*5, maxrequestsize = 1024*1024*5*5)

@MultipartConfig(fileSizeThreshold = 1024*1024, maxFileSize = 1024*1024*5, maxRequestSize = 1024*1024*5*5)
public class BaseController extends FrontController {

}
