Spring+iBatis+Atomikos实现JTA事务
Atomikos是一个公司名字，旗下最著名的莫过于其Atomikos的事务管理器产品。
产品分两个：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
ExtremeTransactions 是基于TransactionEssentials之上的，增加了对非XA事务的支持，在servlet容器中提供了图形化管理控制面板。Atomikos还提供了基于订阅的支持服务，一份订阅可以得到访问ExtremeTransactions中额外功能的权限。
Pardon继续说道，在很多情况下，一个应用服务器对于一个应用也许不是最佳方案 —— 他以SOA/ESB终端作为例子，阐述了通过JDBC来处理JMS消息可能是一个非常轻量级的可伸缩的方案。
关于TransactionEssentials的后继版本，Pardon提到了更强大的JDBC和JMS连接池，支持OSGi 和JMX事务管理工具，是计划中的3.3版的主要特征。Pardon还说明为JDBC数据源和JMS连接器增加JMX是4.0版的目标。
下面是Spring+iBatis+Atomikos实现JTA事务的测试过程：
一、环境
1、准备软件环境
spring-framework-2.5.6.SEC01-with-dependencies.zip
ibatis-2.3.4
AtomikosTransactionsEssentials-3.5.5.zip
MySQL-5.1
JDK1.5
http://www.atomikos.com/downloads/transactions-essentials/3.5.5/AtomikosTransactionsEssentials-3.5.5.zip
ibatis-2.3.4
AtomikosTransactionsEssentials-3.5.5.zip
MySQL-5.1
JDK1.5
http://www.atomikos.com/downloads/transactions-essentials/3.5.5/AtomikosTransactionsEssentials-3.5.5.zip
2、创建数据库环境，注意数据库引擎为InnoDB，只有这样才能支持事务。
CREATE
DATABASE
IF
NOT
EXISTS testdb_a
DEFAULT CHARACTER
SET utf8;
USE testdb_a;
DROP TABLE IF EXISTS tab_a;
CREATE TABLE tab_a (
id bigint(20) NOT NULL,
name varchar(60) DEFAULT NULL,
address varchar(120) DEFAULT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
CREATE DATABASE IF NOT EXISTS testdb_b DEFAULT CHARACTER SET utf8;
USE testdb_b;
DROP TABLE IF EXISTS tab_b;
CREATE TABLE tab_b (
id bigint(20) NOT NULL,
name varchar(60) DEFAULT NULL,
address varchar(120) DEFAULT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
USE testdb_a;
DROP TABLE IF EXISTS tab_a;
CREATE TABLE tab_a (
id bigint(20) NOT NULL,
name varchar(60) DEFAULT NULL,
address varchar(120) DEFAULT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
CREATE DATABASE IF NOT EXISTS testdb_b DEFAULT CHARACTER SET utf8;
USE testdb_b;
DROP TABLE IF EXISTS tab_b;
CREATE TABLE tab_b (
id bigint(20) NOT NULL,
name varchar(60) DEFAULT NULL,
address varchar(120) DEFAULT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
