TransactionProxyFactoryBean总结并测试事务异常
-----------------------------------------------------------------------------------------------------------
不处于事务控制下
无论是否发生导常
都 不提交记录
-----------------------------------------------------------------------------------------------------------
处于事务控制下
发生导常
不提交记录
-----------------------------------------------------------------------------------------------------------
SQL
-----------------------------------------------------------------------------------------------------------
DROP TABLE IF EXISTS `test`.`users`;
CREATE TABLE `test`.`users` (
`id` varchar(32) NOT NULL,
`name` varchar(40) default NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
-----------------------------------------------------------------------------------------------------------
用TransactionProxyFactoryBean测试事务异常
TransactionProxyFactoryBean总结
配置文件最好分开
-----------------------------------------------------------------------------------------------------------
先添加Spring Capabilities
再添加Hibernate Capabilities
-----------------------------------------------------------------------------------------------------------
