import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@table(name = "users")
@entity
public class User {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "user_id", nullable = false, updatable = false)
private Long userId;

@Column(name = "name", nullable = false, length = 100)
private String name;

@Column(name = "email", nullable = false, length = 30)
private String email;

@Column(name = "password", nullable = false, length = 30)
private String password;

@Column(name = "user_type", nullable = false, length = 30)
private String role;

public User() {

}

public User(Long userId, String name, String email, String password, String role) {
    this.userId = userId;
    this.name = name;
    this.email = email;
    this.password = password;
    this.role = role;
}

public Long getUserId() {
    return userId;
}

public void setUserId(Long userId) {
    this.userId = userId;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

public String getRole() {
    return role;
}

public void setRole(String role) {
    this.role = role;
}

}

Did you create this discussion at the wrong repo? We have nothing to do with java.
