#51 💼 Service Layer – Implementing UPDATE Operation – Part 2 (Partial Update – PATCH) in Spring Boot

🎬 #51 💼 Service Layer – Implementing UPDATE Operation – Part 2 (Partial Update – PATCH) in Spring Boot In this video, we continue our Spring Boot training by implementing the UPDATE operation using Partial Update (PATCH) inside the Service Layer. This is Part 2 of the UPDATE series, where we focus on updating only specific fields of an entity instead of the entire object, while keeping data safe and consistent. You will learn how to: ✅ Implement partial update logic in the Service Layer ✅ Validate input data using isBlank() and null checks ✅ Check if the entity exists before updating ✅ Update only the provided fields safely ✅ Avoid overwriting existing data with null values ✅ Handle business exceptions correctly ✅ Understand the difference between PUT and PATCH ✅ Write clean and maintainable update methods ✅ Respect best practices in Spring Boot architecture 🎯 This video helps you master partial updates and avoid common mistakes when working with PATCH requests in Spring applications. 💻 Project GitHub: https://github.com/mohammedezzaim/For... 📞 Contact me: 📧 Email: mohammedezzaim00@gmail.com 💼 LinkedIn:   / mohammed-ezzaim   🐱 GitHub: https://github.com/mohammedezzaim 🔖 Hashtags: #SpringBoot #ServiceLayer #CRUD #Update #PATCH #Java #Backend #JPA #JavaTraining #3IACommunity #Programming #SpringBootArabic #تعلم_البرمجة #جافا #تطوير_ويب
