Can Java Annotations Control User Access? 🤯 | Build a Real Java Access Control System

Can we use Java Annotations to define who can CREATE, UPDATE, or CANCEL an order? 🤯 In this coding challenge, we’ll build an Annotation-Based Order Access Control System from scratch using Core Java. Instead of hardcoding access rules throughout our application, we'll create a custom @AccessRule annotation and attach permissions directly to classes and methods. 🔥 In this project, you'll implement: Custom @AccessRule annotation Annotation attributes for role & operation @Target to control where annotations can be used @Retention(RUNTIME) for runtime access @Inherited for class-level inheritance @Repeatable for multiple access rules @AccessRules container annotation Built-in annotations like @Override, @Deprecated & @SuppressWarnings Java Reflection to read annotations at runtime Class-level and method-level access rules A complete working OrderController example 💡 The real goal: understand how Java annotations move from simple metadata to something that can be inspected and used dynamically at runtime. Perfect for Core Java learners, Java developers, interview preparation, and Spring Boot developers who want to understand what happens behind annotation-driven frameworks. 🔥 Watch till the end to see how Reflection reads the access rules dynamically! #Java #JavaAnnotations #CoreJava #JavaReflection #JavaProgramming #SpringBoot #JavaInterview #CodingChallenge #Programming
