}Spring-test 单元测试数据不自动回滚的解决方案
在使用JUnit做单元测试时，为了使测试数据不对数据库造成污染，故选取了spring-test进行单元测试，但在进行dao层的测试时，发现save方法无法进行数据的自动回滚。
逐一进行检查分析，事务也开启了，并使用注解方式标记@RollBack(true)，在控制台中也打出了事务回滚的信息，但仍然不能自动回滚。
后来感觉是数据库的原因，我的数据库使用的是MySql，这就存在数据表的类型是否支持事务情况。
逐查阅MySql相关文档，发现，InnoDB类型的表是支持事务的，而MyISAM是不支持事务的，立刻查看数据表类型，果然为MyISAM，改为InnoDB后，重新进行测试，问题得到解决。
以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
