Explain the difference between Dynamic Proxies and DI Interceptors.

Updated Apr 28, 2026

Short answer

Interceptors use dynamic proxies to wrap injected objects at runtime, allowing execution of code before and after method calls.

Deep explanation

When an interface is resolved, the DI container generates a proxy class on the fly. This proxy implements the interface, intercepts the method call to run cross-cutting logic (AOP - Aspect Oriented Programming), and then forwards the call to the actual implementation.
