spring 多数据库（数据源） JTA

原创spring多数据库（数据源）JTA事务2收藏

注：本文引自http://malaqu.com/?p=542

最近一个项目要跨多数据，配多数据源的，其中就用到了事务，毫无疑问我选择的是Spring的声明式JTA事务。我的环境是JBOSS+ORACLE9I

自己私下做了些实验，不过还是成功了

实验一：MySQL5.0

这样是成功的可是切换oracle9i时悲剧发生了

—Cause:com.atomikos.datasource.ResourceException:resumeforXIDoracle.jdbc.xa.OracleXid@145f939raised-3:theXAresourcedetectedaninternalerror

Causedby:com.ibatis.common.jdbc.exception.NestedSQLException:

—Theerroroccurredwhileexecutingupdate.

官方说oracle连接问题哎。。。无语了

换了一种JTA事务机制通过JOTM
