Why Does AOP Fail to Intercept Method Calls Within the Same Class?

Understanding AOP Limitations in Method Invocations

You have encountered a common issue where Spring AOP is not invoked when method2 is called within method1 of the same class. To understand the reason behind this, let's dive into the fundamental concepts of AOP in Spring.

In Spring, AOP aspects are applied to proxy objects that surround the actual bean instances. When you obtain a reference to a bean, it is not the original class but a synthetic proxy that implements the relevant interfaces and delegates to the actual class. This proxy adds functionality, including AOP aspects.

In your case, you are directly calling method2 from method1 within the same class, bypassing the bean proxy entirely. Consequently, the AOP aspects defined for method2 will not be triggered.

To address this, there are several alternatives you can consider:

  • Separate bean definition: Split method1 and method2 into separate bean definitions. By doing so, each method will have its own proxy, allowing AOP aspects to be applied to method2 when called separately.
  • Non-Spring AOP framework: Consider using a non-Spring-oriented AOP framework that doesn't rely on proxies and can therefore intercept method calls within the same class.
