Support for Structured Logging is a new Spring Boot feature introduced with the Spring Boot 3.4.0 release. Structured Logging is fairly common to use in distributed environments where you are using some type of consolidated logging. Typically, you will use a JSON log format to allow for easy consolidated log searches with indexing tools such […]Continue reading
Spring AI is the latest project from the Spring Team. Working with Large Language Models (LLMs) has traditionally been the domain of languages such as Python and Javascript. Spring AI is changing this and is enabling integration with generative AI with Java and Spring. In this post, we will take an initial look at using […]Continue reading
JSON Logging in Spring Boot simplifies setup, especially for applications in distributed environments like Kubernetes. Consolidated logging requires searchable logs, often formatted in JSON. Logstash is a popular choice. A basic Logback configuration supports JSON logging, aiding development with profile flexibility. Testing can be done by generating log messages easily.
Spring Boot Microservices requires authentication of users, and one way is through JSON Web Token (JWT). JWT is an open standard (RFC 7519) that defines a compact mechanism for securely transmitting information between parties. In this post, I will explain how to implement JWT authentication in Spring Microservices. JWT Token Overview JWT is of relatively […]Continue reading

If you need to quickly create a JPA-based repository layer, Spring Data JPA is the right choice. You define your repository interface by extending one of the Spring Data JPA Repository interfaces. At runtime, Spring Data JPA will create your repository implementations with the common CRUD methods. You can then perform CRUD operations without writing […]Continue reading
Java 8 introduced a new date and time API defined inside java.time package. The key date and time classes defined in this package are LocalDateTime, ZonedDateTime, and OffsetDateTime. OffsetDateTime represents a date-time with an offset. This class stores all date and time fields, to a precision of nanoseconds, as well as the offset from UTC/Greenwich. For […]Continue reading
Docker Compose defines and runs multi-container Docker applications. It lets you create and start all services from a configuration file with a single docker-compose command. In the previous posts on the Docker series, I discussed how to run Spring Boot on Docker, In this post, I will discuss how to dockerize multiple containers that depend […]Continue reading
Modern Enterprise application development using the Spring framework makes use of containerization technology, such as Docker to ship and run applications. Building an application, packaging it, then building the image, and pushing images to an image registry is cumbersome if done manually. In addition, each time you make any changes to the codebase, you need […]Continue reading
The Spring IoC (Inversion of Control) container manages Spring beans. A “Spring bean” is just a Spring managed instantiation of a Java class. The Spring IoC container is responsible for instantiating, initializing, and wiring beans. The container also manages the life cycle of beans. Spring provides several ways through which you can tap into the […]Continue reading
