Stop bad data in your Spring Boot REST API! Learn input validation step-by-step & ensure data integrity (2025). 💻 Stop bad data from entering your database by implementing robust validation rules in your Java backend. 🛠️ In this crucial tutorial, you will learn how to: ❓ Understand why input validation is critical for any real-world API. ➕ Add the spring-boot-starter-validation dependency to your pom.xml. ✍️ Apply standard Bean Validation annotations (like @NotBlank, @Size, @Min) to your JPA Entities. ✅ Use the @Valid annotation in your REST Controller to trigger validation checks on incoming data. 💥 Implement a controller-specific ExceptionHandler to catch MethodArgumentNotValidException. 💬 Return clean, structured, and user-friendly custom error messages when validation fails. 👀 See the limitations of local handlers and understand why a global solution is often needed. 💻 Technologies Covered: Java ☕ Spring Boot (Validation, Web, Data JPA) 🌱 Jakarta Bean Validation API Postman 📮 🧑‍💻 Who is this tutorial for? Developers wanting to make their Spring Boot APIs more robust and secure. Anyone needing to implement server-side input validation. Programmers looking for practical error handling techniques. Viewers following our Spring Boot CRUD API series. 🎓 💡 What's Next? We demonstrate how a local ExceptionHandler works, but imagine adding that to every controller! It's not ideal. ➡️ In our next video, we'll build a powerful Global Exception Handler – the professional way to manage validation (and other) errors consistently across your entire Spring Boot application!
