使用JTA的事务处理(pro spring ch12范例)问题
在实施<spring专业开发指南>中12章多事务处理范例遇到问题,当指定由JTA管理的事务执行时,相关代码进入异常抛出部分:
TestControl.java
...
try {
accountManager.insert(account);
} catch (Exception ex) {
failures++;
}
...
每次insert都失败,failures值增加.原代码insert部分如下
public void insert(Account account) {
System.out.println("come on,folks");
doInsert(account);
jmsTemplate.send(queue, new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage("foobar");
}
});
if (random.nextInt(10) > 5) {
System.out.println("Fail now");
throw new IllegalArgumentException("fff");
}
}
将随机函数部分关闭后,所有提交仍无法成功.
配置文件如下:

(原文中mbean为
<mbean
code="org.jboss.resource.adapter.jdbc.xa.oracle.OracleXAExceptionFormatter"
name="jboss.jca:service=OracleXAExceptionFormatter">
<depends optional-attribute-name="TransactionManagerService">
jboss:service=TransactionManager</depends>
</mbean>
注意code部分类名区别,这是使用手册的bug)
applicationContext-as.xml有人说要将
<bean id="transactionManager" for Resin 2.x, Oracle OC4J (Orion), JOnAS (JOTM), BEA WebLogic
"java:comp/TransactionManager" for Resin 3.x
"java:pm/TransactionManager" for Borland Enterprise Server and Sun Application Server (Sun ONE 7 and later)
"java:/TransactionManager" for JBoss Application Server
当使用2.0版的的spring.jar代替在二楼贴中的1.2.8版spring.jar和aopalliance.jar后(请注意二楼贴中所列文件的大小和时间),部署spring-ch12.ear时,JBOSS的log:
...

...
至于为何2.0的spring.jar会出现这个问题,"Spring2.0及以后的版本中声明式事务的配置与之前的版本有相当大的不同。主要差异在于不再需要配置TransactionProxyFactoryBean了。" 7 楼 wolf_jack 2007-01-13 楼贴问题基本查出,JTA不能支持代码中的ISOLATION_READ_COMMITTED隔离级别.使用默认级别前述问题消除.
新问题:
1.jms消息发出后,日志:
....
2007-01-13 21:48:49,171 DEBUG [org.jboss.mq.il.uil2.SocketManager] Failed to handle: org.jboss.mq.il.uil2.msgs.CloseMsg22893735[msgType: m_connectionClosing, msgID: -2147483641, error: null]
java.io.IOException: Client is not connected
at org.jboss.mq.il.uil2.SocketManager.internalSendMessage(SocketManager.java:264)
....
很奇怪,因为后面的log显示消息已正确收到并处理.
2.JTA提交报告失败,但在sqlplus中检查,数据已提交
...
2007-01-13 21:48:49,187 DEBUG [org.springframework.transaction.jta.JtaTransactionManager] Committing JTA transaction

继续等待达人路过.-_-# 8 楼 haihai 2007-03-08 看看我的那个用Weblogic做的spring的jta事务的测试，是声明式的事务 9 楼 zzxanadu 2007-08-31 这几天我也把这个例子实现了一下，JMS和JDBC全局事务都回滚成功，没遇到什么问题啊，你有什么问题？？
