*
* A(+事务注解)中调用B(+事务注解):
* A有事务, B无事务
*
* 解决方案:
* 1: bean中自己注入自己, 让A中调用B方法使用注入的自己去调用B方法(testBizService.methodB(), 而不是this.methodB())
* 2: 配置类上声明@EnableAspectJAutoProxy(exposeProxy = true), 然后业务方法((TestBizService) AopContext.currentProxy()).methodB()
* AopContext.currentProxy()其实就是获取的代理对象, bean中注入的自己也是代理对象
