How to create a Spring Boot project in IntelliJ
Introduction
There are so many things I don't understand, so I ran it for the time being and summarized what I can see on localhost.
environment
- Java 12(openjdk 12.0.1) --IntelliJ IDEA 2019.2 (Free version, no problem in Community)
- Mac OS X 10.14.6
Introducing plugins in IntelliJ
--Open the top of IntelliJ (Welcome to IntelliJ IDEA)
--If you have another project open, close it with File-> Close Project
--Lower right Configure-> Open Plugins
--Search for ** Spring Assistant ** from Marketplace and Install
--Restart IntelliJ
Project creation part 1
--Select Create New Project
--Select the ** Spring Assistant ** that you installed earlier on the left side.
--Select Java version in Project SDK
--Spring Initializr server can be left as Default
――I don't know what happens if you choose another one, so please check it yourself.
Project creation part 2
- Project Type → Gradle Project --I've only used Gradle, so for the time being
- Langage → Java
- Package → Jar
--I don't understand the difference between Jar and War
--Java version → It seems to match the Java version selected in the SDK
Project creation part 3
--Added dependency (recommended below)
- Spring Boot DevTools
- Spring Web Starter
- Spring Web Service
- Tymeleaf
――There are various options, so please check it out and use it.
――I would be grateful if you could comment on these features.

--Application.java is created automatically, so you need to create a Controller or write code equivalent to it.
--I will add it when I feel like it
--Create an HTML file in the src / main / resources / templates directory and put it in it
--You can change from the default 8080 to [localhost: 3000](http: // localhost: 3000 /) by adding an appropriate number to resources / application.propaties, such as server.port = 3000.
in conclusion
The Spring framework is full of things I don't understand yet, but I thought it would be very convenient for me to be able to create a new project with IntelliJ!
