This article will explain in detail what the role of Starter in SpringBoot is. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

I. introduction of Starter in official documents

Through the introduction in the official documentation, Starter is actually a "package" provided to us by Spring for unused development scenarios. Similarly, when we go to KFC for dinner, some students may choose their favorite food to place an order, but some students are not so picky about their diet and go directly to the spicy chicken leg burger set meal with high quality and low price. And this spicy chicken leg burger package is the Starter we are going to introduce today.

II. Starter classification

1. Spring officials provide us with a variety of Starter options, about 50 kinds of Starter for us to choose from. Among them, according to partial application, product and technology, it is divided into three categories:

Partial application: Spring Boot application starters

Partial product: Spring Boot production starters

Partial technology: Spring Boot technical starters

2. For the following specific Starter, you can participate in the introduction in the official document:

Official document address: https://docs.spring.io/spring-boot/docs/current/reference/html/using.html#using.build-systems.starters 3. Take a web development scenario as an example to see what spring-boot-starter-web has introduced for us.

1. The Starter of web is first introduced into the pom.xml file in the springboot project, as shown below:

Org.springframework.boot spring-boot-starter-web

2. After the introduction, we found that we downloaded a lot of jar packages one after another. Take a look at the maven dependencies to see which jar packages have been introduced into the project now. As follows:

From the above dependency diagram, we find that web's Starter provides us with the capabilities of webmvc, web, tomcat and json, which can explain why the project can run on its own instead of configuring tomcat.
