Introduction

If you use Pleiades All in One Eclipse, you can easily build the environment just by downloading the zip and unzipping it. However, since Visual Studio Code is popular in the world, I would like to verify how far Java development can be done with this. The goal is to develop a web app using Spring MVC. If you search for the introduction of development using Spring Boot, you will find many hits. Therefore, I dare to try the method that does not use Spring Boot. As of March 2020, there is also a reason that the project we are having is non-Boot Spring MVC web application development.

Environment variable settings

Set environment variables so that JAVA and maven will work no matter where you are in the folder.

JAVA_HOME="D:\JAVA\JDK\jdk-11.0.6+10"
MAVEN_HOME="D:\JAVA\Maven\apache-maven-3.6.3"
Path=%JAVA_HOME%\bin;%MAVEN_HOME%\bin;%Path%

JDK operation check

Open a command prompt and execute the following command.

java -version

D:\>java -version

https://azure.microsoft.com/ja-jp/products/visual-studio-code/ You can download it from here. This time I installed User Installer 64bit.

Visual Studio Code extension installation

Install the "Java Extension Pack". The extensions required for Java development will be installed.

For more information, see the commentary article here. "Building a Java development environment with VS Code" https://www.suzu6.net/posts/130-vscode-for-java/

Install "Tomcat for Java".

Install "Lombok Annotations Support for VS Code".

Summary

The environment has been built.
