为什么我在验证失败时从 Hibernate 收到 UnsupportedOperationException？我希望出现 ConstraintViolationException。
下面是我的 DAO。当它通过验证时，它工作正常。我正在使用 Hibernate 和 Hibernate Validator 4。我正在使用 Websphere 8.0。我认为 WebSphereExtendedJtaPlatform 是罪魁祸首，但我不知道为什么。
如果我查看所谓的 WebSphereExtendedJtaPlatform 源代码(点击源代码链接)，看起来那里的大多数方法都只是抛出 UnsupportedOperationException。
这是我的堆栈跟踪:
org.hibernate.AssertionFailure <init> HHH000099: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session): org.hibernate.AssertionFailure: null id in com.westfieldgrp.beanvalidation.persistence.Car entry (don't flush the Session after an exception occurs)
[11/14/12 16:48:48:785 EST] 00000020 RegisteredSyn E WTRN0074E: Exception caught from before_completion synchronization operation: java.lang.UnsupportedOperationException
at org.hibernate.service.jta.platform.internal.WebSphereExtendedJtaPlatform$TransactionManagerAdapter.setRollbackOnly(WebSphereExtendedJtaPlatform.java:139)
我的堆栈跟踪中的另一个有趣片段:
Entity manager factory name (src_persistence) is already registered. If entity manager will be clustered or passivated, specify a unique value for property 'hibernate.ejb.entitymanager_factory_name'

最佳答案
我最终根据以下链接修改了 WebSphereExtendedJtaPlatform 代码。我很困惑为什么那个类基本上没有实现。
关于java - Hibernate 验证失败时意外的 UnsupportedOperationException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13388069/
