Building High-Performance Apps with Redis, PostgreSQL & Spring Boot #java #javaprogramming #javadev #dormosheio #postgres #springboot #redis

🚀 Spring Boot: If your code uses RestTemplate, you can implement tests by mocking external calls with MockRestServiceServer. ✅ MockRestServiceServer works by intercepting HTTP requests #SpringBoot #JavaDev

Authentication and authorization with Spring-Boot #java #javaprogramming #javadev #dormosheio #springboot #tutorial #springsecurity

Spring Boot: Everything you need to know, and what nobody told you. Part I #java #javaprogramming #javadev #dormosheio #springboot #expert #programming

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

Validation and Exception Handling in Spring Boot #java #javaprogramming #javadev #dormosheio

💡 Java CompletableFuture: chain async steps without blocking the thread on every I/O call. ✅ Chain: supplyAsync, thenApply, thenCompose, thenAccept (fetch user, then orders) #JavaDev

Adding Request Logging to Spring Boot APIs #java #javaprogramming #javadev #dormosheio

🚀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

💡 Java tip: Use StringBuilder instead of String for concatenating strings in loops. ❌ String is immutable, making it inefficient in loops, especially large ones. ✅ StringBuilder is mutable and optimized for repeated string appends. #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 tip: Starting from Java 8, you can remove nulls easily with list.removeIf(Objects::isNull). #Java #JavaDev

🚀 Spring Boot: If your application uses RestTemplate for REST calls, you can centralize timeouts with RestTemplateBuilder . #SpringBoot #JavaDev

🚀Spring Boot: Adding request tracing IDs is important for debugging APIs #SpringBoot #JavaDev

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

Java tip : Starting from Java 19 you can explore a feature called "virtual threads". ✅ Virtual threads are lightweight threads managed by the JVM rather than the OS. #Java #JavaDev
