Spring Boot @Conditional — Hidden superpower ⚡ You can load beans conditionally! Examples: ✅ @ConditionalOnProperty ✅ @ConditionalOnMissingBean ✅ @ConditionalOnClass 💡 Use case: Load bean ONLY when needed Example: @Configuration @ConditionalOnProperty(name="feature.enabled", havingValue="true") 👉 Feature toggles made easy 🔥 ✔ Better flexibility ✔ Environment control ✔ Cleaner configs Most developers don’t use this — big mistake ❌ #SpringBoot #Java #BackendDeveloper

🚀 Using Resilience4j with Spring Boot (Java) To use Resilience4j in a Spring Boot application, include the `resilience4j-spring-boot2` dependency. Annotate your methods with `@CircuitBreaker` to enable the circuit breaker functionality. Configure the circuit breaker properties in your `application.properties` or `application.yml` file, such as the failure rate threshold, the slow call rate threshold, and the wait duration in open state. This allows you to control the behavior of the circuit breaker. #Java #JavaDev #OOP #Backend #professional #career #development
