This article will show you how to use Spring AI support with the most popular AI models for the tool calling feature. Tool calling (or function calling), is a common pattern in AI applications that enables a model to interact with APIs or tools, extending its capabilities. The most popular AI models are trained to […] The post Tool Calling with Spring AI appeared first on Piotr's TechBlog ..read more

This article will teach you how to create a Spring Boot application that implements several AI scenarios using Spring AI and the Ollama tool. Ollama is an open-source tool that aims to run open LLMs on our local machine. It acts like a bridge between LLM and a workstation, providing an API layer on top […] The post Using Ollama with Spring AI appeared first on Piotr's TechBlog ..read more

This article will teach you how to create a Spring Boot application that handles images and text using the Spring AI multimodality feature. Multimodality is the ability to understand and process information from different sources simultaneously. It covers text, images, audio, and other data formats. We will perform simple experiments with multimodality and images. This […] The post Spring AI with Multimodality and Images appeared first on Piotr's TechBlog ..read more

This article will teach you how to create a Spring Boot application that uses RAG (Retrieval Augmented Generation) and vector store with Spring AI. We will continue experiments with stock data, which were initiated in my previous article about Spring AI. This is the third part of my series of articles about Spring Boot and […] The post Using RAG and Vector Store with Spring AI appeared first on Piotr's TechBlog ..read more

This article will show you how to use Spring AI support for Java function calling with the OpenAI chat model. The Spring AI function calling feature lets us connect the LLM capabilities with external APIs or systems. OpenAI’s models are trained to know when to call a function. We will work on implementing a Java […] The post Getting Started with Spring AI Function Calling appeared first on Piotr's TechBlog ..read more

This article will teach you how to use the Spring AI project to build applications based on different chat models. The Spring AI Chat Model is a simple and portable interface that allows us to interact with these models. Our sample Spring Boot application will switch between three popular chat models provided by OpenAI, Mistral […] The post Getting Started with Spring AI and Chat Model appeared first on Piotr's TechBlog ..read more

This article will teach you how to use SAML2 authentication with Spring Boot and Keycloak. Security Assertion Markup Language (SAML) is a standard for exchanging authentication and authorization identities between an Identity Provider (IdP) and a Service Provider. It is an XML-based protocol that uses security tokens with information about a principal. Currently, it is […] The post Spring Boot with SAML2 and Keycloak appeared first on Piotr's TechBlog ..read more

This article will teach you how to use the Eclipse JKube project to build images and generate Kubernetes manifests for the Spring Boot application. Eclipse JKube is a collection of plugins and libraries that we can use to build container images using Docker, Jib, or source-2-image (S2I) build strategies. It also generates and deploys Kubernetes […] The post Spring Boot on Kubernetes with Eclipse JKube appeared first on Piotr's TechBlog ..read more

This article will teach you, how to leverage SBOM support in Spring Boot to implement security checks for your apps. A Software Bill of Materials (SBOM) lists all your app codebase’s open-source and third-party components. As a result, it allows us to perform vulnerability scanning, license checks, and risk analysis. Spring Boot 3.3 introduces built-in […] The post SBOM with Spring Boot appeared first on Piotr's TechBlog ..read more

This article will teach you how to use Backstage in your app development and create software templates to generate a typical Spring Boot app. Backstage is an open-source framework for building developer portals. It allows us to automate the creation of the infrastructure, CI/CD, and operational knowledge needed to run an application or product. It offers a centralized software catalog and unifies all infrastructure tooling, services, and documentation within a single and intuitive UI. With Backstage, we can create any new software component, such as a new microservice, just with a few clicks ..read more
