Я пытался использовать AES с аннотацией hibernate columnTransformer, но дает мне некоторые ошибки.Hibernate @ColumnTransformer (read = "...", write = "...") дает некоторые ошибки, как я могу его решить?
- база данных была сгенерирована с Hibernate.
- Появляется только при попытке использовать AES для чтения и записи параметров на @ org.hibernate.annotations.ColumnTransformer.
Мои Employeeclass
import java.io.Serializable;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Column;
import javax.persistence.Entity;
@Entity()
@Table(name = "EMPLOYEE")
public class Employee implements Serializable {
private static final long serialVesionUID = 1L;
@Id
private Integer employeeId;
@org.hibernate.annotations.NaturalId
private String userName;
@Column(name = "password")
@org.hibernate.annotations.ColumnTransformer(
read = "decrypt('AES', '00', password)",
write = "encrypt('AES', '00', ?)"
)
private String password;
private int accessLevel;
public Employee(Integer employeeId, String userName, String password, int accessLevel) {
this.employeeId = employeeId;
this.userName = userName;
this.password = password;
this.accessLevel = accessLevel;
}
//Getters and Setters
}
Мой Главный класс
import javax.persistence.Persistence;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import hibernate.examples.columntransformers.readandwriteexpressions.Employee;
public class App {
private static EntityManagerFactory emf;
private static EntityManager em;
public static void main(String[] args) {
emf = Persistence.createEntityManagerFactory("LAVM");
em = emf.createEntityManager();
try {
em.getTransaction().begin();
Employee emp = new Employee(123, "someUserName", "somePassword", 1);
em.persist(emp);
em.getTransaction().commit();
} catch (Exception e) {
e.printStackTrace();
} finally {
em.close();
emf.close();
}
}
}
дает мне эти ошибки
