为什么我在验证失败时从Hibernate获得UnsupportedOperationException？我希望有一个ConstraintViolationException。
以下是我的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。
如果我看一下WebSphereExtendedJtaPlatform的源代码（跟随源代码的链接），看起来大多数方法都会抛出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)
我的堆栈跟踪中另一个有趣的片段：
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'

我最终根据以下链接修改了WebSphereExtendedJtaPlatform代码。我很困惑为什么这个课程基本上没有实施。
答案 1 :(得分：2)
我在Websphere Liberty 16.0.0.4上遇到了同样的问题，并通过更改persistence.xml解决了这个问题：
<property name="hibernate.transaction.jta.platform" value="biz.bitech.hibernate.websphere.WebSphereJtaPlatform" />
以下类需要与hibernate库一起位于类路径中：
package biz.bitech.hibernate.websphere;
import javax.transaction.TransactionManager;
import javax.transaction.UserTransaction;
import com.ibm.tx.jta.TransactionManagerFactory;
import com.ibm.tx.jta.UserTransactionFactory;
import org.hibernate.engine.transaction.jta.platform.internal.AbstractJtaPlatform;
public class WebSphereJtaPlatform extends AbstractJtaPlatform {
@Override
protected TransactionManager locateTransactionManager() {
return TransactionManagerFactory.getTransactionManager();
}
@Override
protected UserTransaction locateUserTransaction() {
return UserTransactionFactory.getUserTransaction();
}
}

使用 getEntityManager（）在每个请求上创建一个新的实体管理器。您应该请求（例如通过依赖注入）应用程序范围的持久性管理器。
答案 3 :(得分：0)
请注意，您正在接收来自休眠的HHH000099错误。这是由于GeneratedValue返回null并且当hibernate执行插入时，它会将null传递给您的PK。
我认为您的ID会随表一起自动递增。将Generated value设置为AUTO / TABLE / IDENTITY时，Hibernate会在表中查找值。如果你坚持这个表，这不应该是一个问题。
我遇到了类似的问题，我所做的就是将列设为insertable = false。
希望有所帮助。

以下代码来自hibernate-core 4.3.7.FINAL（SynchronizationCallbackCoordinatorNonTrackingImpl）
在重新打包和发送异常之前，您将看到对setRollbackOnly的调用，对于WebSphereExtendedJtaPlatform，它只会抛出一个不受支持的操作异常，这是您在日志中看到的。此时，由于您从未达到重新打包运行时异常的程度，因此它将丢失。
但不知何故，hibernate设法将其记录到stdout，因此您将在SystemOut.log文件中找到您的SQL异常
