Protobuf Integration with Netty Protocol Buffers Overview Protocol Buffers (Protobuf) is Google's language-neutral, platform-neutral mechanism for serializing structured data. It's more efficient than XML for data exchange due to its binary format. The protocol supports various languages including Java, C++, C#, Go, and Python. This makes it ...

Java Plugin Implementation Approaches ServiceLoader Mechanism Java's ServiceLoader provides a standard SPI implementation. Define an interface with multiple implementations, then load them dynamically: public interface NotificationService { void sendAlert(String message); } public class EmailNotifier implements NotificationService { @O ...

Redis provides efficient counting capabilities suitable for rate limiting and access tracking. Common use cases enclude blog view counters and SMS verification code frequency limits. Basic counters face challenges like preventing refresh-triggered increments. The solution involves tracking user access within specific time windows and storing da ...

Securing stateless REST APIs relies heavily on short-lived access tokens paired with longer-lived refresh credentials. This pattern prevents frequent re-authentication while limiting exposure from compromised tokens. Below is a practical implementation of this mechanism using Spring Boot, Spring Security, and the JJWT library. Core Dependencies ...
