spring boot的aop现在都是用代理实现的，ControllerAdvice连代理都不是，为什么是aop呢

ai是个好东西:

在Spring框架中，AOP（面向切面编程）的实现通常是通过代理来完成的。但是，AOP的概念并不仅限于代理。AOP是一种编程范式，其核心**是将那些与业务无关，但在多个地方被重复使用的代码（例如日志、事务管理、安全检查等），抽取出来，形成一个独立的模块，这个模块就是切面（Aspect）。

在Spring MVC中，@ControllerAdvice注解可以被视为一种AOP的应用，虽然它并不是通过代理来实现的。@ControllerAdvice注解可以定义全局的异常处理器，这个处理器可以捕获所有控制器抛出的异常。这就是一种横切关注点（Cross-cutting Concerns）的体现，也就是AOP的核心**。

所以，即使@ControllerAdvice并不是通过代理来实现的，但是它的功能（全局异常处理）符合AOP的概念，因此我们可以将其视为AOP的一种应用。
