Question

I\'ve the following entity:

@Entity
public class Employee implements Serializable{
    private static final long serialVersionUID = 3454567L;

    @Id
    @G         


        

Answer 1

Your class should have the fields mapped to the table column using annotation like

@Entity
@Table(name="employee")
public class Employee implements Serializable{
    private static final long serialVersionUID = 3454567L;

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @cloumn(name="emp_id")
    private int empId;

    @Column(name="user_name")
    private String username;

    public int getEmpId() {
        return empId;
    }

    public void setEmpId(int empId) {
        this.empId = empId;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }
}
