[JAVA] I tried to create a Spring MVC development environment on Mac

Introduction

――For various reasons, I created a Spring development environment. ――It was a break, but I was able to build it in a total of about 3 or 4 hours while fitting smoothly. ――I would like to continue to promote Spring-related activities in the future.

Points that fit, points that I did not understand well

--Introduction of Eclipse

There are many options for Eclipse, such as using various versions and Pleades directly, downloading from the original home or installing from Homebrew.

--How to make a project

At first, it was promoted from Maven project to Spring environment, but I wasn't sure because there are various setting methods. Also, it became much easier because I found a package that can create templates such as STS on the way.

--Tomcat runs normally

When I played around with it, the execution environment broke, and I didn't know where to play with it. It is good to erase the workspace and start over.

--How to resolve the dependency

I was lucky enough to know that I needed to install it using Maven, not just adding it to pom.xml.

What I don't understand well

--Differences between Spring, Spring MVC, Spring Boot, etc.

If you don't squeeze it properly when you check this area, it may fit.

--Difference between Maven and Gradle

I tried using Gradle, but do I have to set the xml by myself? Maven was all made of screen pops.
