无法使用Hibernate分配默认user_role="ROLE_USER“

Question

我有一个用户模型，当用户注册时，我尝试在我的postgreSQL数据库中设置一个默认的role="role_user“。我的用户模型是：

 @Entity
@Table(name = "users")
public class User {
@NotEmpty(message = "Campul nu poate fi lasat gol")
@Size(min = 4, max = 16,message = "Dimensiunea trebuie sa fie intre 4 si 16 caractere")
private String firstName;

@NotEmpty(message = "Campul nu poate fi lasat gol")
@Size(min = 4, max = 16,message = "Dimensiunea trebuie sa fie intre 4 si 16 caractere")
private String lastName;

@Id
@NotEmpty(message = "Campul nu poate fi gol")
@Email(message = "Email-ul trebuie sa fie valid")
private String email;

@NotEmpty(message = "Campul nu poate fi gol")
@Size(min = 4, max = 60, message = "Parola trebuie sa contina minim 4 caractere")
private String password;

private String role;

private boolean enabled = true;

public User() {};
public User(String firstName, String lastName, String email, String password,String role) {
    this.firstName = firstName;
    this.lastName = lastName;
    this.email = email;
    this.password = password;
    this.role = role;

}

我怎么才能解决这个问题呢？我在stackoverflow上看到了另一个帖子，但我不明白，我是Spring的新手

您可以使用默认值初始化您的字段。

private String role = "role_user";

public User(String firstName, String lastName, String email, String password,String role) {
     this.firstName = firstName;
     this.lastName = lastName;
     this.email = email;
     this.password = password;
     if(role != null) { this.role = role; }; // if you need to keep the default value
 }
