@Transactional(rollbackFor = Exception.class)作用于类上

引用提到了`@Transactional(rollbackFor=Exception.class)`注解，这是一个用于处理事务的注解。当这个注解作用于类上时，它的作用是指定了当类中的方法抛出异常时，事务将会回滚，也就是之前操作的数据库数据将会被还原。换句话说，如果类上加了`@Transactional(rollbackFor=Exception.class)`注解，那么类中的方法抛出异常时，事务将会回滚并且数据库的数据也会回滚。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
