The following code shows the implementation of an employee entity
as
Employee.java
:
@Entity
@Table(name = "EMPLOYEE")
public class Employee {
@Id
private String employeeId;
@Column
private String employeeName;
@Column
private String address;
@Column
private String department;
public Employee() {
// Default constructor.
}
// getters and setters.
}
Once the employee entity is created, implement the
create, read, update and
delete
(
CRUD
) operations to be performed:
private static EntityManagerFactory emf = Persistence
.createEntityManagerFactory("hbaseTest");
private static EntityManager em = emf.createEntityManager();
