Question

我无法提交我的弹簧表格。我得到了这个例外，不知道为什么：

javax.validation.ConstraintViolationException: validation failed for classes [com.example.my.entities.User] during persist time for groups [javax.validation.groups.Default, ]

这是我的用户实体：

@Entity
@Table( name = "tbl_user" )
public class User implements Serializable
{
  private static final long serialVersionUID = 1L;

  @Id
  @GeneratedValue
  @Column( name = "id", nullable = false, columnDefinition = "serial" )
  private int id;

  @NotEmpty
  @Length( max = 255 )
  @Column( name = "username", unique = true, nullable = false, length = 255 )
  private String username;

  @NotEmpty
  @Column( name = "password", nullable = false, length = 32 )
  private String password;

  @NotEmpty
  @Transient
  private String confirmPassword;

  @NotEmpty
  @Email
  @Length( max = 255 )
  @Column( name = "email", unique = true, nullable = false, length = 255 )
  private String email;

  @Length( max = 255 )
  @Column( name = "role", length = 255 )
  private String role;

  @OneToMany( fetch = FetchType.LAZY, mappedBy = "id.user", cascade = { CascadeType.REMOVE }, orphanRemoval = true )
  private List<LicenseUserAlert> alerts;

  public int getId()
  {
    return id;
  }

  public void setId( int id )
  {
    this.id = id;
  }

  public String getUsername()
  {
    return username;
  }

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

  public String getPassword()
  {
    return password;
  }

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

  public String getConfirmPassword()
  {
    return confirmPassword;
  }

  public void setConfirmPassword( String confirmPassword )
  {
    this.confirmPassword = confirmPassword;
  }

  public String getEmail()
  {
    return email;
  }

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

  public String getRole()
  {
    return role;
  }

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

  public List<LicenseUserAlert> getAlerts()
  {
    return alerts;
  }

  public void setAlerts( List<LicenseUserAlert> alerts )
  {
    this.alerts = alerts;
  }
}

我正确地填写了表格，所以不应该有任何约束违规...... 也许有任何与confirmPassword有关的错误吗？

您应该考虑将@NotNull注释confirmPassword放在非默认验证组中。

即使我相信OR-Mapper验证@Transient字段是一个错误。但JPA或Hibernate可能有其他意见。 - 如果您可以验证问题是否属于该瞬态字段，并且您同意我的意见，那么您可以在hibernates bug跟踪器上发布一个tickt。

<强>加出于一些奇怪的原因，即使用@Transient标记了hibernate，它仍然可以验证字段。查看此论坛https://forum.hibernate.org/viewtopic.php?f=9&t=1009600&start=0

另一个想法是不使用实体来包含仅用于GUI的字段。所以你可以从实体对象中分离表单数据容器（命令对象）。
