求助 [Java SSH 配置问题]

哪位大佬告诉小弟一声：为什么sessionFactory 总是Autoweired 失败？

以下是报错——

SSH系列教材 （五）- 使用XML方式配置事务管理
MAGIC_LAN的博客

作为一个事务里的方法，当i==2的时候，抛出异常，这个事务就回滚了，在i==0,i==1的时候插入到数据库里的两条数据，也就回滚了。的，所谓的非侵入式，就是指不需要修改一行java代码，只需要进行applicationContext.xml的配置，即可达到事务管理的效果。在Mysql中，只有当表的类型是INNODB的时候，才支持事务，所以需要把表的类型设置为INNODB,否则无法观察到事务.当i==2的时候，抛出一个运行时异常，这样，就只创建了2条，而不是本来计划5条数据。
