/Aspect（切面）: 横切关注点的模块化E
2JoinPoint（连接点）: 程序执行的某个点G
4Pointcut（切入点）: 匹配连接点的表达式I
/Advice（通知）: 在连接点执行的动作K
3Weaving（织入）: 将切面应用到目标对象M
adviceTypesO
@Before - 方法执行前Q
3@After - 方法执行后（无论成功或异常）S
'@AfterReturning - 方法成功返回后U
&@AfterThrowing - 方法抛出异常后W
%@Around - 环绕通知（最强大）Y

benefits
*解耦：发布者和监听者互不依赖<00>
-扩展：新增监听器无需修改发布者<00>
'异步：耗时操作不阻塞主流程<00>
$测试：更容易进行单元测试<00>
