Cross-cutting interceptors can be added to command handlers using Before, After, Around, and Presend attributes. These attributes inject logic such as transactions or logging into handler execution via a flexible pointcut system without modifying core business logic.

Message headers can be modified before or after handler execution using the changeHeaders capability. This header enrichment functionality is available for Before, After, and Presend interceptors to inject data like correlation IDs.

Execution order of multiple interceptors applied to the same handler is controlled using configurable precedence settings. You can assign precedence levels to Before, After, Around, and Presend attributes to ensure interceptors execute in the correct sequence.

An around interceptor safely proceeds with the original method invocation by calling MethodInvocation::proceed(). This allows the interceptor to execute custom logic before and after delegating to the actual handler.

You do not need to explicitly define pointcuts for every interceptor because the system supports auto-inference. You can rely on automatic pointcut inference or configure explicit pointcuts when more precise targeting is necessary.
