     * Transactional 注解 可以作用于接口、接口方法、类以及类方法上。当作用于类上时，该类的所有 public 方法将都具有该类型的事务属性，同时，我们也可以在方法级别使用该标注来覆盖类级别的定义。
     * <p>
     * 虽然@Transactional 注解可以作用于接口、接口方法、类以及类方法上，但是 Spring 建议不要在接口或者接口方法上使用该注解，因为这只有在使用基于接口的代理时它才会生效。另外， @Transactional注解应该只被应用到 public 方法上，这是由Spring AOP的本质决定的。如果你在 protected、private 或者默认可见性的方法上使用 @Transactional 注解，这将被忽略，也不会抛出任何异常。
     * <p>
     * 默认情况下，只有来自外部的方法调用才会被AOP代理捕获，也就是，类内部方法调用本类内部的其他方法并不会引起事务行为，即使被调用方法使用@Transactional注解进行修饰。
