Most people do not understand the knowledge points of this "how to get started with SpringBoot" article, so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "how to get started with SpringBoot" article.

What is Spring Boot?

Spring Boot is not a new framework, it improves and optimizes the shortcomings of Spring, Spring Boot defaults to a lot of ways to use the framework, such as maven integrates all jar packages for the same reason. And SpringBoot are not enhancements to Spring, but provide a quick way to use Spring.

Why use Spring Boot?

Here's what Spring Boot officially says: Spring Boot is based on the starting point of Spring development projects. Spring Boot is designed to let you run Spring applications quickly and minimize configuration files. When using the SSM framework, we developers waste a lot of time in the configuration, and the Spring Boot framework for you to reduce these tedious configuration, but you focus on business logic coding, so as to improve the efficiency of development.

Brief introduction

Springboot provides a quick way to use spring, based on the idea of coc, that is, conventions outweigh configuration. Developers do not have to switch between the configuration and the logic business, and devote themselves to the coding of the logic business, thus greatly improving the efficiency of development. Springboot, which was released in 14 years, is a very new technology, and springboot is one of spring's top projects.

Shortcomings of spring

Spring is great to use, but there is something annoying about it.

Tedious configuration

The components of spring are lightweight, but the configuration is heavyweight. When we use the spring framework, we have to write a lot of configuration xml or annotations, our thinking will switch back and forth between the business code and the spring configuration, and the development efficiency will be reduced.

Rely on tedious

Each component of spring has different dependencies. When building the environment, you need to analyze the coordinates of which libraries to import, as well as the coordinates of other libraries that are dependent on it. Once you choose the wrong dependent version, the resulting incompatibility will seriously hinder the progress of the project development.

The function of springboot

What we need to know is that springboot is not an enhancement to spring functionality, but rather provides a quick way to use spring.

Automatic configuration

The automatic configuration of SpringBoot is a process at run time (or, more accurately, when the application starts). Many factors are considered before deciding which spring configuration should be used and which should not be used. This process is done automatically by springboot.

Start dependence

In the past, we guided the coordinates of the jar package one by one, but now springboot wraps all the packages of a certain function together to provide some default functions.

Auxiliary function

Provides some common non-functional features in large projects, such as embedded server, security, indicators, health detection, external configuration and so on.

Getting started with SpringBoot

Now we want to complete the requirement with springboot: define the hello method of the HelloController class and return "Hello SpringBoot".

If we use spring to do this, that is to import a lot of coordinates, then define classes, annotate, and write xml configuration

Now we use springboot to build the environment, and pom.xml only needs to write the following

The default packaging method for springboot is jar.

Org.springframework.boot spring-boot-starter-parent 2.1.8.RELEASE org.springframework.boot spring-boot-starter-web

Idea provides a way to quickly build springboot

We can quickly create a springboot project by selecting spring Initializr when we create the project.

Fill in the information related to the project

Then you can add web support

Then idea will automatically create the springboot project environment, and the coordinates of the maven will be guided.
