Jsf 2 bean验证和jsf2集成

我使用此处描述的跨域验证作为示例

它们可以完美地工作，并抛出一个javax.ejb.EJBTransactionRolledbackException以及所有违反的约束的列表。但是我需要在元素中显示错误消息。从来都不是。是因为这是类级注释吗？字段上注释的验证始终在页面上显示其消息

有人能解释一下吗

更新：

我不会发布验证器，因为它们是从链接上的示例复制和粘贴的，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>

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();
    }
}

调用具有entityManager.persist的方法时，会引发异常，堆栈跟踪上会显示所有约束冲突，但@compareStrings页面中不会显示任何冲突。如果仅违反@notblank（或字段上的任何其他注释），则正确显示消息

Kelly你能给我们一个简短的代码示例吗？您的问题标题涉及JSF，但您的异常说明了一些关于EJB的内容。我想这基本上回答了我的问题。。。。

@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();
    }
}
