Commands

Scaffold

There are several commands the main one is the scaffold where it generates for you the model, repository, service, controler and the view with thymeleaf.

When running spring scaffold -n "User" -p "name: String email: String"

This command generates all crud operation

you will see.

created src/main/java/com/example/model/UserModel.java
created src/main/java/com/example/repository/UserRepository.java
created src/main/java/com/example/service/UserService.java
created src/main/java/com/example/controller/UserController.java
created src/main/resources/layout.html
created src/main/resources/templates/user/index.html
created src/main/resources/templates/user/form.html
created src/main/resources/templates/user/show.html

with this simple command you already have a complete crud (create, read, update, delete).
