Spring AOP is deeply integrated into the broader Spring ecosystem, leveraging the Inversion of Control (IoC) container to provide its core capabilities. The Spring IoC container is responsible for managing the lifecycle and configuration of application beans. When you enable AOP in your Spring application, the container plays a crucial role by creating proxy objects that wrap your beans. These proxies intercept method calls and apply cross-cutting concerns, such as logging, security, or transaction management, without you having to modify your business logic. This seamless integration allows you to declaratively add behavior to beans at runtime, making AOP a natural extension of Spring's core dependency injection and bean management facilities.

At the heart of Spring AOP are several infrastructure beans that work together to enable aspect-oriented features within the application context. Key among these are the ProxyCreator beans, which are responsible for generating proxy instances around your target beans. These proxies delegate method invocations to the appropriate advice as defined by your aspects. Other important infrastructure elements include the Advisor beans, which encapsulate both the pointcut (where advice should be applied) and the advice itself (what action to perform), and the Aspect beans, which group related advices together. All these components are registered and managed within the Spring application context, ensuring that AOP concerns are applied consistently and efficiently throughout the bean lifecycle.
