Spring Security is a powerful and highly customizable authentication and access-control framework for Java applications. Whether you are building a small application or a large enterprise system, securing your application is paramount. In this article, we'll explore how to get started with Spring Security, focusing specifically on username and password authentication. What is Spring…
Introduction Spring Boot is a popular framework for building Java-based web applications. It simplifies the development process by providing default configurations and a variety of tools for creating stand-alone, production-grade applications. Ollama is a hypothetical API service for machine learning tasks (e.g., text generation, image processing, etc.). In this tutorial, we will build a…
In Spring Boot applications, WebClient is a powerful tool for making HTTP requests to external services. However, sometimes you need to intercept and modify these requests or responses for various reasons such as logging, authentication, or adding custom headers. This is where interceptors come into play. Interceptors allow you to intercept and manipulate the…
Spring Boot is a popular framework for building Java-based applications, offering a range of features to facilitate the development process. One such feature is dependency injection, which allows for the automatic wiring of beans in the Spring context. However, this automatic wiring can sometimes lead to issues, such as the NoUniqueBeanDefinitionException. In this article,…
Introduction:In the realm of Spring Boot applications, developers often encounter various exceptions, each carrying its own significance and requiring a unique approach for resolution. One such exception is the BeanCurrentlyInCreationException, which can be quite puzzling for developers. In this article, we'll delve into what this exception signifies, explore its common causes, and provide solutions…
Spring Boot, part of the larger Spring Framework ecosystem, offers a powerful and flexible framework for building Java-based applications. One of the core features of Spring is its robust dependency injection mechanism, which simplifies the development of loosely coupled applications. However, this mechanism can occasionally produce exceptions when misconfigured. One such exception is the…
Spring Boot is a powerful framework that simplifies the development of Java applications, particularly web applications. One of its core features is dependency injection (DI), which allows the framework to manage the dependencies of various components automatically. However, sometimes developers encounter an UnsatisfiedDependencyException, which occurs when Spring cannot resolve a dependency for a bean.…
Spring Boot is a powerful framework for building microservices and standalone applications. It simplifies the process of creating robust applications by providing default configurations and embedded servers. However, even with these conveniences, developers can encounter various exceptions, one of which is the ApplicationContextException. This exception indicates an issue with the Spring ApplicationContext, a central…
