JtaTransactionManager在“刷新”期间提交失败后没有回滚

标签： java spring hibernate jta spring-transactions


更新：我正在使用Bitronix TM对其进行测试，并且它完美地回滚，因此问题出在JBoss TM（arjuna）或我的配置中。

更新2：看起来事务不是全局的，我尝试过不同的数据源，Bitronix数据源有 allowLocalTransactions 属性，在设置之后我的应用程序抛出一个异常，有些东西试图在本地模式下使用它。如果我将Bitronix与此数据源一起使用，它可以正常工作而不会出现任何错误。我相信配置有问题。

我遇到了JTA交易的问题。我正在使用Tomcat 7 + Hibernate 4 + Spring 3 + JBoss TS 4和JTA交易。

假设有以下方法：

@Transactional(propagation = Propagation.REQUIRED)
public void testMethod() {
    insertOfSomeNewEntityInstance();
    updateOfAnotherEntity();
}

private void insertOfSomeNewEntityInstance() {
    SomeEntity entity = new SomeEntity();
    someEntityDAO.save(entity);
}

private void updateOfAnotherEntity() {
    AnotherEntity anotherEntity = anotherEntityDAO.findBySomeProperty(1L);
    anotherEntity.incrementSomeValue();
    anotherEntityDAO.save(anotherEntity);
}

如果此方法抛出“org.hibernate.StaleObjectStateException：在”updateOfAnotherEntity（）“方法执行或任何其他事务中，行被另一个事务更新或删除（或未保存的值映射不正确）”在“flush”期间可能发生的运行时异常（Hibernate还显示： HHH000346：托管刷新期间出错[行被另一个事务更新或删除（或未保存的值映射不正确）。 然后，不会回滚insertOfSomeNewEntityInstance（）执行的结果。

调试此问题后，我在org.springframework.transaction.jta.JtaTransaction Manager中找到了“doCommit”方法

@Override
    protected void doCommit(DefaultTransactionStatus status) {
        JtaTransactionObject txObject = (JtaTransactionObject) status.getTransaction();
        try {
            int jtaStatus = txObject.getUserTransaction().getStatus();
            if (jtaStatus == Status.STATUS_NO_TRANSACTION) {
                throw new UnexpectedRollbackException("JTA transaction already completed - probably rolled back");
            }
            if (jtaStatus == Status.STATUS_ROLLEDBACK) {
                try {
                    txObject.getUserTransaction().rollback();
                }
                catch (IllegalStateException ex) {
                    if (logger.isDebugEnabled()) {
                        logger.debug("Rollback failure with transaction already marked as rolled back: " + ex);
                    }
                }
                throw new UnexpectedRollbackException("JTA transaction already rolled back (probably due to a timeout)");
            }
            txObject.getUserTransaction().commit();
        }
        catch (RollbackException ex) {
            throw new UnexpectedRollbackException(
                    "JTA transaction unexpectedly rolled back (maybe due to a timeout)", ex);
        }
        catch (HeuristicMixedException ex) {
            throw new HeuristicCompletionException(HeuristicCompletionException.STATE_MIXED, ex);
        }
        catch (HeuristicRollbackException ex) {
            throw new HeuristicCompletionException(HeuristicCompletionException.STATE_ROLLED_BACK, ex);
        }
        catch (IllegalStateException ex) {
            throw new TransactionSystemException("Unexpected internal transaction state", ex);
        }
        catch (SystemException ex) {
            throw new TransactionSystemException("JTA failure on commit", ex);
        }
    }

如果“txObject.getUserTransaction（）。commit（）;”使用RollbackException失败然后此方法抛出UnexpectedRollbackException，这是org.springframework.transaction.support.AbstractPl atformTransactionManager processCommit（...）的一部分，它捕获它：

}
 catch (UnexpectedRollbackException ex) {
                // can only be caused by doCommit
                triggerAfterCompletion(status, TransactionSynchronization.STATUS_ROLLED_BACK);
                throw ex;
    }

我没有在triggerAfterCompletion（）方法中看到任何回滚，在此方法之后，其他一切只是清理资源。

总结，spring / jboss只提交insertOfSomeNewEntityInstance（）的结果，由于并发修改错误而无法执行updateOfAnotherEntity（），并且不回滚任何内容。如果我从updateOfAnotherEntity（）手动抛出任何运行时或检查异常，它会正确回滚，只有当Hibernate在“flush”期间抛出一些运行时异常时才会出现问题。

我发现问题出在配置中。 Tomcat XA池不了解JBoss Transaction Manager。我试图将driverClassName更改为TransactionalDriver，如下所示：

<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.XADataSource" destroy-method="close">
        <property name="defaultAutoCommit" value="false" />
        <property name="url" value="jdbc:arjuna:" />
        <property name="driverClassName">
            <value>com.arjuna.ats.jdbc.TransactionalDriver</value>
        </property>
        <property name="username" value="${database.user}" />
        <property name="password" value="${database.password}" />
        <property name="initialSize" value="${database.pool.initialSize}"/>
        <property name="maxActive" value="${database.pool.maxSize}"/>
        <property name="maxIdle" value="${database.pool.maxSize}"/>
        <property name="connectionProperties" value="DYNAMIC_CLASS=com.example.CustomDatasourceLoader;"/>

不幸的是，它为子事务抛出一个异常，说连接属于另一个事务，所以我必须找到另一个连接池。         

Oracle UCP池也无法正常工作，没有办法将driverClassName更改为TransactionalDriver，因为它是硬编码到OracleDriver。

以下配置适用于我（DBCP XA池）并正确回滚，提交，支持子事务：

<bean id="oracleXADataSource" class="oracle.jdbc.xa.client.OracleXADataSource">
        <property name="user" value="${database.user}"/>
        <property name="password" value="${database.password}"/>
        <property name="URL" value="${database.url}"/>
    </bean>

    <bean id="dsXAConnectionFactory" class="org.apache.commons.dbcp.managed.DataSourceXAConnectionFactory">
        <constructor-arg><ref bean="arjunaTransactionManager"></ref></constructor-arg>
        <constructor-arg><ref bean="oracleXADataSource"></ref></constructor-arg>
    </bean>

    <bean id="pool" class="org.apache.commons.pool.impl.GenericObjectPool">
        <property name="maxActive" value="${database.pool.maxSize}"/>
        <property name="minIdle" value="${database.pool.initialSize}"/>
    </bean>

    <bean id="poolableConnectionFactory" class="org.apache.commons.dbcp.PoolableConnectionFactory">
        <constructor-arg name="connFactory" ref="dsXAConnectionFactory"/>
        <constructor-arg name="pool" ref="pool"/>
        <constructor-arg name="stmtPoolFactory"><null></null></constructor-arg>
        <constructor-arg name="validationQuery"><null></null></constructor-arg>
        <constructor-arg name="defaultReadOnly" value="false"/>
        <constructor-arg name="defaultAutoCommit" value="false"/>

    <bean id="dataSource" class="org.apache.commons.dbcp.managed.ManagedDataSource" depends-on="poolableConnectionFactory">
        <constructor-arg name="pool" ref="pool"/>
        <constructor-arg name="transactionRegistry" value="#{dsXAConnectionFactory.getTransactionRegistry()}"/>
    </bean>
