I need to verify the email of the new user who would like to sign up in my application web. if the email is already in my database (mysql) so must don't accept this sign up and said said to him like: "your email already used". Now I can save users in my database, but how to check them by his email for not repeat the inscription in my application web.
this is my Dao layer class :
public class UserDaoMysql implements UserDao {
private Session session;
private void openSession(){
SessionFactory sessionFactory=HibernateUtil.getSessionFactory();
session = sessionFactory.openSession();
session.beginTransaction();
}
private void closeSession(){
session.getTransaction().commit();
session.close();
}
public void insert(User user) {
if(checkEmail(user)){
openSession();
User p = new User(user.getName(), user.getEmail(), user.getPassword());
session.save(p);
System.out.println("sauvegarde reussi");
closeSession();
}
}
public boolean checkEmail(User user){
return true;
}
}
this is my user bean :
@ManagedBean(name="user")
public class User {
private int id;
private String name;
private String email;
private String password;
private String confirmationPass;
// private image
public User() {
super();
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getConfirmationPass() {
return confirmationPass;
}
public void setConfirmationPass(String confirmationPass) {
this.confirmationPass = confirmationPass;
}
public User(int id, String name, String email, String password,
String confirmationPass) {
super();
this.id = id;
this.name = name;
this.email = email;
this.password = password;
this.confirmationPass = confirmationPass;
}
public User(int id, String name, String email, String password) {
super();
this.id = id;
this.name = name;
this.email = email;
this.password = password;
}
public User(String name, String email, String password) {
super();
this.name = name;
this.email = email;
this.password = password;
}
@Override
public String toString() {
return "User [id=" + id + ", Name=" + name + ", email=" + email
+ ", password=" + password + "]";
}
public void save(){
UserBusiness userBusiness = new UserBusinessImp();
userBusiness.add(new User(name, email,password));
}
}
And I created a table "user" in my database.
Maybe there is an annotation which can help us to specify the email property as an unique one or something else.
