Introducing AOP in Spring Boot

Let’s dive into AOP. You might be wondering: what’s AOP all about? Well, it’s a programming approach that helps separate concerns in your application, especially the ones that cut across multiple parts of your app, such as logging, transaction management, or security. Think about the logging; you can add a logger line in every method. AOP helps you keep them separate, so your main code stays clean and focused on what it’s supposed to do. It again logs the required data as a part of a separate class.

Spring Boot has built-in support for AOP, making it easier for you to implement these cross-cutting concerns without turning your code into spaghetti. With AOP, you can define advice (which means AOP speaks for the code that should run at a certain point), pointcuts (where in your code you want that advice to run), and aspects (the combination of advice and pointcuts). This means you can automatically apply common functionality...
