💡 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

🚀 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 Tip💡: Starting from Java 14 you can use "record" to create short, immutable, data-carrying objects. ✅ They are shorter than ordinary POJOs ✅ They have built-in equals(), hashCode(), toString() ✅ They are immutable by default #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
