解决办法：

 @Before("execution(public * com.e_pet.biz.*.*(..))")
1. public void before(String a,int b){
  System.out.println("事务执行之前就执行了这个方法！");
  HibernateSessionFactory.beginTransaction();
       
 }
2.    @After("execution(public * com.e_pet.biz.*.*(..))")
 public void afterReturning(){
  HibernateSessionFactory.commitTransaction();
  System.out.println("事务执行之后就执行了这个方法！");
 }
3.   @AfterThrowing("execution(public * com.e_pet.biz.*.*(..))")
 public void afterThrowing(){
  System.out.println("提交数据发生异常时就执行了这个方法！");
  HibernateSessionFactory.roolbackTransaction();
 }

就像 1 那样，就会导致上面的错误信息显示，并且也不会有注解的标识符号！
