Spring Boot focuses on the Spring platform and third-party development libraries, simplifying the development of Spring-based products. So that you will not be troubled by various complicated affairs when you start Spring application development. Through Spring Boot, only a small amount of Spring configuration can be used to complete the initial construction of the project structure during development.
Features
- Create standalone Spring applications.
- Embeds Tomcat, Jetty and Undertow directly (no need to deploy WAR files).
- Simplified Maven configuration with specific POM files.
- Automatically configure Spring as much as possible.
- Provides product-level features such as metrics measurement, health checks, external configuration, etc.
- Absolutely no code generation or XML configuration .
The Reference Manual provides detailed descriptions of all functions, as well as usage guidelines for commonly used functions .
quick start
Spring Boot provides command-line tools to quickly prototype Spring applications. Configurable via Groovy scripting means no familiarity with Java syntax and a lot less template code. In the documentation, you can refer to Install the Spring Boot CLI using the command line.
If you are a Java developer, you can use start.spring.io to generate a basic project structure, then refer to the "Quick Start" example below, or read the beginner's guide .
It is recommended to use spring-boot with a dependency management system - copy and paste this script into your build. What if you are not familiar with these? See the chapter on building with Maven and Gradle in the Beginner's Guide.
