I have following code:
@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
@Entity
@Table
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column(name = "FIRST_NAME")
private String firstName;
@Column(name = "LAST_NAME")
private String lastName;
@NotNull
@Column(name = "LOGIN", unique = true)
private String login;
@Column(name = "PASSWORD")
private String password;
@Column(name = "ROLE")
private UserRole role;
@Column(name = "E_MAIL", unique = true)
private String email;
@Convert(converter = UserStrategyConverter.class)
@Column(name = "STRATEGY")
private UserStrategy userStrategy;
@Column(name = "SUBSCRIPTION")
private Boolean subscription;
@Column(name = "MONEY")
private BigDecimal money;
My problem: When I put this object from postman in json:
{
"firstName": "Daniel",
"lastName": "xxx",
"password": "daniel",
"role": "ROLE_USER",
"email": "[email protected]",
"subscription": false,
"money": "1200"
}
It create object in entity. Problem is because I can multiply this object again and again instead of unique = true
in columns (email
and login
). Can anyone explain me why?

Hibernate will take into account the constraint unique = true
only at the time of schema generation.
During schema generation the following constraint will be added:
alter table User
add constraint UK_u31e1frmjp9mxf8k8tmp990i unique (email)
If you do not use the schema generation there is no sense of using unique = true
.
