spring-@Transactional-jar
当我们在实现类上添加了@Transactional注解时,表示该类的方法将被包装成一个事务。这样,在方法执行期间,将会启动一个事务,并在方法执行结束后,根据方法的执行结果决定是提交事务还是回滚事务。注意,Spring团队建议将@Transactional注解添加在具体的类(或类的方法)上,而不是接口上。因为注解不能继承,如果使用基于类的代理,那么在接口上使用@Transactional注解将不会生效。所以,请遵循Spring团队的建议,在具体的类上使用@Transactional注解。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
