In this I have tried the Registration Form in Model View Control architecture. I am unable to Store the User Data In Another class. In that the Registration field Has to be stored in the Registration Database Class and Contact information has to be stored in the Contact Information Class.
Then how Should I frame Main method
public class RegistrationData {
private String username;
private String password;
private Contact contact;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Contact getContact() {
return contact;
}
public void setContact(Contact contact) {
this.contact = contact;
}
public RegistrationData(String username, String password, Contact contact) {
this.username = username;
this.password = password;
this.contact = contact;
}
}
public class Contact {
private String name;
private String phoneNumber;
private String emailId;
public Contact(String name, String phoneNumber, String emailId) {
this.name = name;
this.phoneNumber = phoneNumber;
this.emailId = emailId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public String getEmailId() {
return emailId;
}
public void setEmailId(String emailId) {
this.emailId = emailId;
}
}
public class Registration {
Scanner scanner = new Scanner(System.in);
void Registration(RegistrationData registrationData,Contact contact){
System.out.println("Username : ");registrationData.setUsername(scanner.next());
System.out.println("Password : ");registrationData.setPassword(scanner.next());
System.out.println("Name : ");contact.setName(scanner.next());
System.out.println("PhoneNumber : ");contact.setPhoneNumber(scanner.next());
System.out.println("Email id :");contact.setEmailId(scanner.next());
}
}
//Data Base Class
import java.util.ArrayList;
import java.util.List;
public class RegistrationDatabase {
List<RegistrationData> registrationData = new ArrayList<>();
public void storeData(RegistrationData registrationData){
this.registrationData.add(registrationData);
System.out.println(this.registrationData);
}
}
import java.util.LinkedList;
import java.util.List;
public class ContactDatabase {
List<Contact> contacts = new LinkedList<>();
public void addContact(Contact contact){
this.contacts.add(contact);
}
}
Correct me If I am wrong in interpreting you question
Assumption 1 :
You want to Store registration data to RegistrationInformation table from Contact Information class as well as from RegistrationInformation class
Solution 1:
As I can see there is one to one relation between Contact and registration,so You can add a association in ContactInformation class as well as you have done in RegisterInformation class
public class Contact {
//one to one relation
private RegistrationData registrationData;
.
.
.
.
and use this to store registration from Contact
Assumption 2 :
You have seperate database for Contact and Registration
Solution 2:
In that case Create a POJO class for Registration form(same as RegistrationData,but will be used to capture data from view) and then create two classes RegistrationData and Contact class and then Use the POJO to retrieve and store the information in both the database.

This will be quite a bit of code as I don't know what will be important. I was trying to recreated the basic UI Alejandro made in my tutorial session with him a few months ago, substituting a table in my database for the one he used. The errors I'm getting all seem related to overriding Vaadin Flow functions. I know that replaces the behavior of the Super method. IntelliJ opens the relevant Super method when I click on the errors, which I'm assuming it wants me to edit to solve the problem, but I have no idea how to do that.
I was going to paste a link to the code but the forum told me to just place it here.

To serialize your entity, your CustomerEntity should be public, so it should be defined in a separate file. Also note not to declare properties in constructor method.
Here's the code for you to refer.
package table;
import com.microsoft.azure.storage.table.TableServiceEntity;
public class CustomerEntity extends TableServiceEntity {
public CustomerEntity(String lastName, String firstName) {
this.partitionKey = lastName;
this.rowKey = firstName;
}
public CustomerEntity() { }
String email;
String phoneNumber;
public String getEmail() {
return this.email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPhoneNumber() {
return this.phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
}
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.
What you can do is create a unique key on your email column in your table. After that, decorate your field using #Column(unique=true), that will indicate to Hibernate that this field has a unique key.
Also, be careful with your annotations. This is unrelated to your problem, but #ManagedBean marks the class as a bean able to interact with the view in JSF. Probably you want/need to use #Entity instead.
I am programming an IHM for sign up the users, I need to check if this user is already in database(mysql), checking by his email . can you help me please.
I can save my user now but how to check if this user by his email
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 have a table user in my database.
thanks for your help in advance
I would use NamedQuery for this. Define named query in your User entity like this:
...
#NamedQueries({
#NamedQuery(name = "User.findByEmail",
query = "SELECT u FROM User u WHERE u.email = :email")})
#ManagedBean(name="user")
public class User {
...
And then add method like this to your DAO
public List<User> getUsersByEmail(String email){
openSession();
Session session;
Query query = session.getNamedQuery("User.findByEmail");
query.setString("email", email);
Lis<Users> users = query.list();
closeSession();
return users;
}
This method is little bit more generic you can make it more specific returning user count only.
Given the following class:

}
public enum Roles implements GrantedAuthority {

}
}
}
I get a compilation exception here:
public Rating rate(Movie movie, int stars, String comment) {

}
Following the tutorial here. Any insight as to where this function resides is appreciated.
You're trying to use the advanced mapping mode. See the reference manual for more information. You'll need to set up AspectJ support in your IDE. Methods are woven into your entity classes at compile time.
