Introduction to Spring Boot

Spring Boot makes it easy to create stand-alone, production-grade Spring-based Applications that you can run. We take an opinionated view of the Spring platform and third-party libraries, so that you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration.
You can use Spring Boot to create Java applications that can be started by using java -jar or more traditional war deployments. We also provide a command line tool that runs “spring scripts”.
Our primary goals are:
  • Provide a radically faster and widely accessible getting-started experience for all Spring development.
  • Be opinionated out of the box but get out of the way quickly as requirements start to diverge from the defaults.
  • Provide a range of non-functional features that are common to large classes of projects (such as embedded servers, security, metrics, health checks, and externalized configuration).
  • Absolutely no code generation and no requirement for XML configuration.

    System Requirements


    Spring Boot 2.1.2.RELEASE requires Java 8 and is compatible up to Java 11 (included). Spring Framework 5.1.4.RELEASE or above is also required.
    Explicit build support is provided for the following build tools:
     

    Build Tool                  Version

    Maven                                        3.3+

    Gradle                                         4.4+

Data pipelines in Python

  Data pipelines in Python play a crucial role in efficiently processing, transforming, and transporting data from various sources to destinations. Python provides a rich ecosystem of libraries and tools for building robust and scalable data pipelines. Here's a guide on creating data pipelines in Python: 1. Define Pipeline Components: Identify the different stages of your data pipeline. Common components include data extraction, transformation, loading (ETL), and data storage. Break down the pipeline into modular components for better maintainability. 2. Choose a Pipeline Orchestration Framework: Consider using a pipeline orchestration framework to manage the workflow of your pipeline. Popular choices include Apache Airflow, Luigi, and Prefect. These tools help schedule, monitor, and execute tasks in a defined sequence. 3. Use Data Processing Libraries: Leverage Python libraries for data processing, such as: Pandas: Ideal for data manipulation and analysis. NumPy: Essential fo...

How to send custom metrics with OpenTelemetry in java

  OpenTelemetry is an observability framework that allows you to collect, process, and export telemetry data such as traces and metrics from your applications. In Java, sending custom metrics with OpenTelemetry involves a few key steps. The following steps assume that you have already set up OpenTelemetry in your Java project. 1. Dependency Setup: Make sure you have the necessary dependencies in your project. Add the OpenTelemetry API, SDK, and the metrics module to your pom.xml (if you are using Maven): <dependencies> <!-- OpenTelemetry API and SDK --> <dependency> <groupId>io.opentelemetry</groupId> <artifactId>opentelemetry-api</artifactId> <version>1.7.0</version> <!-- Use the latest version --> </dependency> <dependency> <groupId>io.opentelemetry</groupId> <artifactId>opentelemetry-sdk</artifactId> <vers...

Unleashing Responsiveness: The World of Reactive Spring Boot Applications

  Introduction: In the fast-paced realm of modern software development, where responsiveness, scalability, and resilience are paramount, reactive programming has emerged as a game-changer. Reactive Spring Boot applications represent a paradigm shift in how we build and deploy robust, highly concurrent, and low-latency systems. This essay explores the principles of reactive programming, the integration of these principles into the Spring Boot framework, and the transformative impact on application development. Understanding Reactivity: Reactive programming is rooted in the principles of responsiveness, elasticity, and message-driven communication. At its core, reactivity is about building systems that can efficiently handle a massive number of concurrent operations with a focus on responsiveness, ensuring that the system reacts promptly to user input and external events. Key Components of Reactive Spring Boot: Spring WebFlux: ·        ...
