A detailed explanation of the concepts and knowledge points related to Spring Boot
Spring Boot is an open-source J**A framework designed to simplify the creation and deployment of Spring applications. Spring Boot enables developers to quickly build production-grade Spring applications through automatic configuration and starters. Below we will explain some of the core concepts of Spring Boot in detail.
Spring Boot's automated configuration is one of its core features. It automatically configures your Spring application based on the JAR dependencies contained in the project. For example, if you added in your projectspring-boot-starter-webdependency, Spring Boot automatically configures all web-related beans, such as:dispatcherservletrequestmappinghandleradapterWait.
Starter dependencies are a set of predefined dependencies that simplify the configuration of m**en or gradle builds. Spring Boot provides a number of official starter dependencies, such as:spring-boot-starter-webUsed to build web applicationsspring-boot-starter-data-jpaIt is used for database operations using JPA, etc. Developers can quickly introduce the required libraries and configurations by simply adding the appropriate starter dependencies to the project's build files.
The Spring Boot Command Line Interface (CLI) is a stand-alone tool that allows you to quickly develop Spring applications from the command line. It provides an embedded Groovy interpreter for running Groovy scripts. Developers can use the Spring Boot CLI to quickly create and run Spring applications without the need for traditional build and deployment.
The Actuator is a sub-project of Spring Boot that monitors and manages Spring Boot applications. It provides a set of production-ready endpoints to display your application's health information, environmental attributes, metric data, and more. With Actuator, developers can easily monitor and manage the running status of Spring Boot applications.
Spring Boot Admin is a tool for managing and monitoring Spring Boot applications. It provides a simple UI interface for displaying the information provided by the Spring Boot Actuator endpoint. Spring Boot Admin can monitor multiple instances of Spring Boot applications and provide functions such as health checks, log viewing, and environment attribute viewing.
Spring Boot can embed servers such as Tomcat, Jetty, or Undertow, eliminating the need to deploy applications to external containers. This makes it easier for developers to develop and test Spring applications, while also simplifying the process of deploying applications.
Spring Initializr is a web application for quickly generating skeletons for Spring Boot projects. Developers only need to select the required project type, package name, project name, starting dependencies and other information on the web interface of Spring Initializr to generate a Spring Boot project with basic configuration and file structure.
Spring Boot simplifies the process of creating and deploying Spring applications by automating configurations, starting dependencies, and more. It provides a rich set of tools and components, such as Actuator, Spring Boot Admin, etc., for monitoring and managing applications. In addition, Spring Boot also supports features such as embedded servers and Spring Initializr, further improving the development efficiency and convenience of developers.
