💡Spring Boot tip: Use TaskScheduler to implement lightweight dynamic tasks (consider Quartz for more complex requirements). #SpringBoot #JavaDev 🧵Text example to follow:

🚀 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: If you need to inject grouped configuration properties into classes, you can use @ConfigurationProperties instead of @Value #SpringBoot #JavaDev

💡Java: Use WeakHashMap for caching when the unreferenced keys should be garbage-collected. #Java #JavaDev

💡Java tip: Starting from Java 14 you can use switch expressions for shorter and cleaner multi-branch logic. #Java #JavaDev

💡Java: Prefer delegation over inheritance; an "is-a" relationship ties you to the superclass forever ✅ A subclass inherits the parent's entire API; a change upstream can break your code ✅ With delegation, you hold a helper object and forward calls; easy to mock #JavaDev 🧵

💡 Spring Boot: Better avoid logging inside tight loops, since you could affect the application performance and flood log files. #SpringBoot #JavaDev

💡 Java tip: Starting from Java 12 you can use String.transform(Function) to apply lambdas directly to strings. #Java #JavaDev

🚀 Spring Boot: To execute SQL scripts before or after a test method, you can use the @Sql annotation. #SpringBoot #JavaDev

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

Java Tip 💡: Use Files.walk() to recursively process files in a directory. #Java #JavaDev

💡 Spring Boot: You can run jobs at fixed intervals without setting up Quartz or external schedulers. #SpringBoot #JavaDev
