💡 SpringBoot: Define @ComponentScan boundaries carefully to avoid to avoid scanning entire packages accidentally. #SpringBoot #JavaDev
🚀 Spring Boot: Choose WebClient over RestTemplate for new apps. ✅ It's reactive and non-blocking ✅ Based on event-loop instead of thread-per-request ✅ Ideal for microservices #SpringBoot #JavaDev
🚀 SpringBoot: You can add global OpenAPI metadata with @OpenAPIDefinition. ✅ Put it on your main Spring Boot application class, or a dedicated configuration class #SpringBoot #JavaDev
💡Spring Boot tip: Use TaskScheduler to implement lightweight dynamic tasks (consider Quartz for more complex requirements). #SpringBoot #JavaDev 🧵Text example to follow:
🚀 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
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
💡 Java tip: Use Files.readString() and Files.writeString() for straightforward file I/O. #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: Catch mistakes at compile time annotating overridden methods with @Override. #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, you can use String.strip() instead of trim(), since it handles Unicode whitespaces correctly. #Java #JavaDev
💡Java tip: Use List.copyOf(list) for a safe, unmodifiable copy, while avoiding accidental changes. #Java #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
💡 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
