[转]Spring+iBatis+JOTM兑现JTA事务

[转]Spring+iBatis+JOTM实现JTA事务
Spring+iBatis+JOTM实现JTA事务?JOTM是个开源的JTA事务管理组件，可以让程序脱离J2EE容器而获得分布式事务管理的能力。?测试过程如下：?一、环境?1、准备软件环境
?spring-framework-2.5.6.SEC01-with-dependencies.zip
?ibatis-2.3.4
?ow2-jotm-dist-2.1.4-bin.tar.gz
?MySQL-5.1
?JDK1.5?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;?

}?然后将主键其中一个改掉进行测试，让另外一个主键重复，发现a、b数据库均不能成功写入，经过多次测试，验证jtom真正实现了分布式事务的管理。附：org.springframework.transaction.jta.JotmFactoryBean在spring2.5.6中可以拷贝直接用
