🚀 Spring Boot: A webhook is when another system sends a POST request to your app when something happens. In Spring Boot, you implement it simply by exposing an endpoint that receives that POST request. #SpringBoot #JavaDev

🚀 Spring Boot tip: With Spring Boot and Spring Security you can secure endpoints easily. #SpringBoot #JavaDev

🚀 Spring Boot: Spring Data JPA has a built-in support for pagination with Pageable. ✅You should use pagination in your repositories instead of fetching all. #SpringBoot #JavaDev

💡 Java CompletableFuture: chain async steps without blocking the thread on every I/O call. ✅ Chain: supplyAsync, thenApply, thenCompose, thenAccept (fetch user, then orders) #JavaDev

🚀 JUnit 5 Tip 🚀 Since JUnit 5, leverage package-private visibility for classes and methods to enhance encapsulation in your tests. This helps keep your testing logic close to the code it's testing while maintaining a clean and organized codebase. #JUnit #Testing #JavaDev

Java tip : Starting from Java 19 you can explore a feature called "virtual threads". ✅ Virtual threads are lightweight threads managed by the JVM rather than the OS. #Java #JavaDev

🚀 Spring Boot: You can enable /actuator/beans to debug missing beans. By hitting the actuator endpoint, you will see information like: ✅ Bean name ✅ Bean type ✅ Bean scope ✅ Bean dependencies #SpringBoot #JavaDev

🚀Spring Boot: Adding request tracing IDs is important for debugging APIs #SpringBoot #JavaDev

💡 Java: Records are not limited to data only, you can add custom constructors or methods for validation. ✅ They can have constructors, static methods, and instance methods: #Java #JavaDev

💡Java: Use Deque instead of Stack for LIFO (last-in, first-out) lists. ✅ Stack is a legacy class, it extends Vector and synchronizes every operation ✅ Deque supports the same push, pop, peek calls ✅ ArrayDeque is faster than Stack #JavaDev

🚀 Spring Boot: To make Jackson create your objects from JSON in an explicit, and predictable way, you can use @JsonCreator. 🟢 Each parameter is explicitly bound #SpringBoot #JavaDev

🚀Spring Boot integrates easily with Kafka to implement event-driven architectures. 🧵1/3 #SpringBoot #JavaDev

Spring Boot makes you feel like you’re doing a lot less, but actually building a lot more. That’s framework design done right. #JavaDev #SpringBoot #ayshriv
