🚀 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

🚀 Spring Boot: Use @TestConfiguration to use test-specific beans that must not be loaded in production. #SpringBoot #JavaDev

Java tip: Starting from Java 9 you can use Stream.takeWhile() for easy slicing of lists by streams. #Java #JavaDev

💡 SOLID Principles: Interface Segregation Principle (ISP) states that clients shouldn’t depend on methods they don’t use. ✅ Large, general-purpose interfaces should be broken down into smaller, more specific ones. #Java #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: To make your services return a paginated response, instead of a giant list, you can use Page<T> and Pageable. #SpringBoot #JavaDev 🧵A link to an example to follow:

💡 Java tip: Starting from Java 11, you can use String.strip() instead of trim(), since it handles Unicode whitespaces correctly. #Java #JavaDev

💡 SpringBoot: Define @ComponentScan boundaries carefully to avoid scanning entire packages accidentally. #SpringBoot #JavaDev

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

🚀 Spring Boot: Use @SpringBootApplication(exclude = …) to disable specific auto-configuration classes. ✅ One possible reason is a custom configuration that conflicts with the default. #SpringBoot #JavaDev

💡 Java tip: From Java 9 you can use Objects.checkIndex(...) to replace manual if checks for validating index bounds. ✅It is a small feature that helps making the code cleaner. #Java #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 tip💡: If you have a list of elements, you want to remove duplicates, and sort them in natural order or by a custom comparator, you can use TreeSet. #Java #JavaDev

🚀Java: Starting from Java 14, you can use records 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 #JavaDev #Records

💡Spring Boot tip: If you need to implement integrations tests for Spring MVC controllers, and mock everything else, use @WebMvcTest to load only MVC-related beans. #SpringBoot #JavaDev
