When working with UUIDs in Scala using json4s, you might run into issues serializing and deserializing UUID objects by default. Json4s does not handle java.util.UUID out-of-the-box. Fortunately, there’s a simple and elegant solution using JavaTypesSerializers. To enable UUID support in json4s, you can add JavaTypesSerializers.all to your implicit formats: When working with Java types like…
When working on APIs, secure endpoints often need an easy way to authorize requests during development and testing. Swagger (via Springdoc OpenAPI) lets us integrate JWT-based authentication directly into the UI. Here’s a breakdown of the configuration that makes this happen: Let’s break this down: Components Section: This part defines a new security scheme called…
Issue Description When starting Kubernetes in Docker Desktop, you may encounter the following error while pulling images: This issue occurs due to authentication failures while trying to pull images from Docker Hub or the Kubernetes image registry. Solution: Re-authenticate with Docker Hub A quick and effective fix is to log out and log back into…
When working with Java applications, you may encounter the following error like I did: This issue arises because your code is attempting to use the internal sun.security.x509.X500Name class. Starting with Java 9, the Java Platform Module System (JPMS) restricts access to internal APIs such as sun.security.*, making them inaccessible unless explicitly allowed. Why This Happens…
There are multiple ways to enable CORS in Spring Boot. Enable CORS Globally To apply CORS settings to all endpoints in your Spring application, you can use the WebMvcConfigurer interface. Enable CORS for Specific Endpoints You can use the @CrossOrigin annotation to enable CORS for specific controllers or methods. This approach is ideal if you…
In the brief span of human existence, typically limited to a mere 70 or 80 years, our lives are intricately woven from the threads of our daily actions, each year, month, and day contributing to the tapestry. It is in this finite timeframe that we strive to achieve a balance between fulfilling relationships, financial stability,…
In Single Sign-On (SSO) using Security Assertion Markup Language (SAML), there are two primary flows: Identity Provider (IdP)-initiated and Service Provider (SP)-initiated. Here’s a detailed comparison between the two: 1. SP-Initiated SAML Flow Flow: User Requests Access: The user tries to access a resource or application (the SP). Redirect to IdP: The SP redirects the…
It might seem as if the journey towards self-knowledge could proceed in a relatively smooth and linear way. But the battle between the forces of repression and the drive towards self-awareness tends to be far more bitter and entrenched than that. For years, there can be stalemate, neither side yielding ground until the pressure to…
Rancher is a widely-used open-source platform for managing Kubernetes clusters. It provides various features and tools to simplify the deployment, management, and operation of Kubernetes clusters. One important aspect of working with Rancher and Kubernetes is understanding the kube config. What is kube config? In Rancher, the kube config is a configuration file that contains…
Integrating PMD (Programming Mistake Detector) into a Spring Boot Gradle application can help improve code quality by identifying potential issues, bugs, and anti-patterns in the codebase. PMD is a static code analysis tool that scans source code for common programming mistakes and provides feedback to developers to help them write better code. In this article,…
