Question

我使用此处描述的交叉字段验证Cross field validation with Hibernate Validator (JSR 303)

作为示例

它们完美地工作，并且抛出了javax.ejb.EJBTransactionRolledbackException以及所有违反的约束的列表。但我需要在元素中显示错误消息。它永远不会。是因为这是一个类级别的注释吗？在字段上注释的验证始终在页面上显示其消息。

有人可以解释一下吗？

更新

我不会发布验证器，因为它们是从链接上的示例复制并粘贴的，但我的页面是这样的

<h:form id="registration_form" class="form-horizontal" prependId="false">
  <h:messages errorClass="alert alert-error no-bullets" infoClass="alert alert-info no-bullets" globalOnly="false"/>
<div class="form-actions">
 <h:commandButton id="create_button" value="#{label['save']}" action="#{actionBean[save]}" class="btn btn-primary" />
<button class="btn">#{label['cancel']}</button>
</div>
  </div>

因此，我的所有错误消息都应该出现在。我的实体bean是这样的：

@Entity
@Table(name="user")
@CompareStrings(propertyNames={"password", "passwordConfirmation"})
@NamedQueries({
@NamedQuery(name = User.FETCH_BY_NAME, query = "select u from User u where u.name like :username"),
@NamedQuery(name = User.FETCH_ALL, query = "select u from User u")})
public class User implements Serializable{
private static final long serialVersionUID = 1L;

public static final String FETCH_BY_NAME = "fetchByName";

public static final String FETCH_ALL = "fetchAll";

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id", updatable = false, nullable = false)
private Long id;

@Column(name = "name")
@NotBlank
@Username
private String name;
   .....
  }

我的托管bean：

@Named("userBean")
@Stateful
@ConversationScoped
 public class UserBean implements Serializable {
   @Inject
private Conversation conversation;
@EJB
private UserManagerBeanLocal userController;
public String update() {
   //calls a method that only has entityManager.persist();
    }
}

当调用具有entityManager.persist的方法时，抛出异常，所有约束违规都显示在堆栈跟踪上，但@compareStrings的页面中没有显示任何约束违规。如果仅违反@notblank（或字段上任何其他注释），则会正确显示该消息。
