Spring+iBatis+Atomikos实现JTA事务

Atomikos分两个:一个是开源的TransactionEssentials,一个是商业的ExtremeTransactions。

  TransactionEssentials的主要特征:JTA/XA 事务管理 -- 提供事务管理和连接池不需要应用服务器 -- TransactionEssentials可以在任何Java EE应用服务器中运行,也就是不依赖于任何应用服务器开源 -- TransactionEssentials是遵守Apache版本2许可的开源软件专注于JDBC/JMS -- 支持所有XA资源,但是资源池和消息监听是专供JDBC和JMS的与Spring 和 Hibernate 集成 -- 提供了描述如何与Spring和Hibernate集成的文档

  一、环境

  spring 2

  ibatis2

  AtomikosTransactionsEssentials-3.7.0 下载地址:http://www.atomikos.com/Main/InstallingTransactionsEssentials

  MySQL-5.1 :数据库引擎为InnoDB,只有这样才能支持事务

  JDK1.6

  Oracle10

  二 jar包

  Atomikos jar必须包 transactions-jdbc.jar

  transactions-jta.jar

  transactions.jar

  atomikos-util.jar

  transactions-api.jar

  ibatis,spring

  只要符合二者集成jar组合即可,无额外jar

  三、配置

  Oracle用户授权:(视情况而定,如果程序出现如下异常则需要加上1672 [main] WARN atomikos - ERROR IN RECOVERY com.atomikos.datasource.ResourceException: Error in recovery)

  grant select on sys.dba_pending_transactions to orcl;

  grant select on sys.pending_trans$ to orcl;

  grant select on sys.dba_2pc_pending to orcl;

  grant execute on sys.dbms_system to orcl;

  jta.properties 配置文件,即src/ jta.properties内容如下:

  view source <http://www.cnblogs.com/warison2008/archive/2010/10/15/1852338.html>

  print <http://www.cnblogs.com/warison2008/archive/2010/10/15/1852338.html><http://www.cnblogs.com/warison2008/archive/2010/10/15/1852338.html>

  1com.atomikos.icatch.service=com.atomikos.icatch.standalone.UserTransactionServiceFactory

  2 com.atomikos.icatch.console_file_name = tm.out

  3com.atomikos.icatch.log_base_name = tmlog

  4com.atomikos.icatch.tm_unique_name = com.atomikos.spring.jdbc.tm

  5com.atomikos.icatch.console_log_level = INFO
