Now I want to get users from postgres database can you help me please? have you any tuto or books?

Answer 1

As example (respecting Roland Krügers example) for Spring Boot Application + SpringSecurity + Vaadin4Spring # Hibernate, you have to define the following properties in application.properties:
# DATASOURCE
spring.datasource.url=jdbc:postgresql://localhost/myDB
spring.datasource.username=myuser
spring.datasource.password=mypwd
spring.datasource.driverClassName=org.postgresql.Driver
spring.datasource.xa.data-source-class-name=org.postgresql.xa.PGXADataSource
spring.datasource.pinGlobalTxToPhysicalConnection="true"
# one transaction manager via view
spring.jpa.open-in-view=true
# for mapping models and attributes to table names and column names
spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.EJB3NamingStrategy
spring.jta.default-transaction-timeout=2000
Using application.properties in your app add the following annotation to your main class:
#PropertySources({
#PropertySource({"classpath:application.properties"})
})
Now an entity of a user can look like:
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
#Entity
#Table(name = "USER")
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "ID", nullable = false, updatable = false)
private Long id;
#Column(name = "LAST_NAME", nullable = false)
private String lastName;
#Column(name = "FIRST_NAME", nullable = false)
private String firstName;
#Column(name = "LOGGED_IN")
private boolean loggedIn;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public boolean isLoggedIn() {
return loggedIn;
}
public void setLoggedIn(boolean loggedIn) {
this.loggedIn = loggedIn;
}
}
After that you have to define a repository interface for Hibernate:
/**
*Spring auto repository for database access of User objects.
**/
public interface UserRepository extends JpaRepository<User, Long> {
Optional<User> findOneByName(String userName);
}
Now you can do something like that in your login method:
...
vaadinSecurity.login(userName.getValue(), passwordField.getValue());
Optional<User> ouser = userRepository.findOneByName(userName);
if (ouser.isPresent()) {
User user = ouser.get();
user.setLoggedIn(true);
}
...
