🚀 Spring Boot: Use @SpringBootApplication(exclude = …) to disable specific auto-configuration classes. ✅ One possible reason to do so could be that you have a custom configuration that conflicts with the default. #SpringBoot #JavaDev
💡 Java tip: Starting from Java 8 you can use List.removeIf(<predicate>) to clean up collections in one line. #Java #JavaDev
🚀 Spring Boot: In development phase, use spring.main.lazy-initialization=true to speed up the startup of the application. #SpringBoot #JavaDev
💡 Java tip: Use Files.readString() and Files.writeString() for straightforward file I/O. #Java #JavaDev
🚀 You can use async logging in Spring Boot by configuring logback (logback-spring.xml). ✅ Log messages are sent into a queue, and are elaborated by a separate background thread. ✅ This reduces I/O bottlenecks. #SpringBoot #JavaDev
💡Spring Boot tip: Use @Profile to group and load beans/configurations in specific environments. #SpringBoot #JavaDev
🚀 Spring Boot: If you need to inject grouped configuration properties into classes, you can use @ConfigurationProperties instead of @Value #SpringBoot #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: Use Objects.requireNonNullElse(value, defaultValue) to avoid null checks. #Java #JavaDev
💡 Spring Boot: To better handle circular dependencies, use constructor injection instead of field injection. ✅ Forces all required dependencies to be provided at creation time, allowing early detection. #SpringBoot #JavaDev
🚀 Spring Boot tip: With Spring Boot and Spring Security you can secure endpoints easily. #SpringBoot #JavaDev
💡Java tip: Starting from Java 15 you can use String.formatted(...) for string formatting instead of String.format(...). #Java #JavaDev
💡 Java tip: Use parallelStream() with care. It's ideal for CPU-intensive tasks, not I/O operations. #Java #JavaDev
Java tip: Starting from Java 11, if you need to repeat n times a specific string, you can use the String method repeat(n). #Java #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 tip: Starting from Java 11, you can use String.strip() instead of trim(), since it handles Unicode whitespaces correctly. #Java #JavaDev

Yesterday’s Kenya JUG session with Thomas Vitale was 🔥 Loved diving deeper into Spring AI, intelligent apps, and all the conversations around memory, LLMs, and system design. Always grateful for this community — can’t wait for the next one! #KenyaJUG #SpringAI #JavaDev
💡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

🚀 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

Now, the compiler implicitly declares the class for you, and you can use a simpler void main() method. There is also a new, simplified IO class in java.lang package for basic console I/O, which is implicitly imported. #Java #JavaDev #JavaProgramming #JDK25
