Spring JTA配置 - 如何设置TransactionManager？ [英] Spring JTA configuration - how to set TransactionManager?

问题描述

我们将Spring配置中的Spring事务配置为：

We configure our Spring transaction in Spring config as:

<tx:jta-transaction-manager/>

我收集这意味着Spring会自动发现底层的JTA实现。因此，当我们启动JBoss时，我们会在Spring搜索时看到这些消息：

I gather this means that Spring will automatically discover the underlying JTA implementation. So when we start up JBoss we see these messages while Spring searches:

[JtaTransactionManager] [ ] No JTA TransactionManager found at fallback JNDI location [java:comp/Tran
sactionManager]
javax.naming.NameNotFoundException: TransactionManager not bound
<<Big stack trace>>    
<<More of the same>>

然后最终看到：

[JtaTransactionManager] [ ] JTA TransactionManager found at fallback JNDI location [java:/Transaction
Manager]
[JtaTransactionManager] [ ] Using JTA UserTransaction: org.jboss.tm.usertx.client.ServerVMClientUserT
ransaction@1f78dde

问题是 - 我们如何编辑我们的< tx：jta-transaction-manager /> 用于显式配置 java：/ Transaction Manager JTA实现的标签我们避免了日志中的所有这些堆栈跟踪？ （我不想只更改Log4J日志记录级别）

Question is - how can we edit our <tx:jta-transaction-manager/> tag to explicitly configure the java:/Transaction Manager JTA implementation so we avoid all these stack traces in the logs? (I'd prefer not to just change the Log4J logging levels)

更新：我用下面的配置替换< tx：jta-transaction-manager /> 它似乎有效..我猜这是好的吗？

Update: I replaced <tx:jta-transaction-manager/> with the below config and it seems to work.. i'm guessing this is alright?

<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
    <property name="transactionManagerName" value="java:/TransactionManager"/>
</bean>

推荐答案

是的，没关系。您看到的堆栈跟踪也没问题：< tx：jta-transaction-manager /> 尝试从多个不同的标准位置获取事务管理器;对于每个失败的JNDI查找，您将看到 javax.naming.NameNotFoundException 。

Yes, that's alright. The stack trace you were seeing was also alright: <tx:jta-transaction-manager/> tries to acquire the transaction manager from a number of different standard locations; for every failed JNDI lookup, you'll see the javax.naming.NameNotFoundException.

java：/ TransactionManager 是JBoss默认绑定的地方;其他servlet容器将默认为 java：/ comp / TransactionManager ，我认为它应该是TM的标准位置。

java:/TransactionManager is where JBoss binds to by default; other servlet containers will default to java:/comp/TransactionManager, which I think is supposed to be the "standard" location for the TM.

来自 Spring参考文档：

对于标准方案，包括
WebLogic，WebSphere和OC4J，请考虑
使用方便的

这意味着您将不必为

For standard scenarios, including WebLogic, WebSphere and OC4J, consider using the convenient <tx:jta-transaction-manager/> configuration element. This will automatically detect the underlying server and choose the best transaction manager available for the platform. This means that you won't have to configure server-specific adapter classes (as discussed in the following sections) explicitly; they will rather be chosen automatically, with the standard JtaTransactionManager as default fallback.
