🚀 Spring Boot tip: With Spring Boot and Spring Security you can secure endpoints easily. #SpringBoot #JavaDev
💡Spring Boot tip: Use @Profile to group and load beans/configurations in specific environments. #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
💡 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
💡 Java tip: Use Files.readString() and Files.writeString() for straightforward file I/O. #Java #JavaDev
💡Java tip: Use List.copyOf(list) for a safe, unmodifiable copy, while avoiding accidental changes. #Java #JavaDev
