Helper in learning Spring Boot

Relatively recently I started learning the Spring Framework. I immediately studied both theory and practice. Having made a sufficient number of simple web applications, I became good at creating CRUD applications. https://ru.wikipedia.org/wiki/CRUD I wanted to slightly automate the process of developing web applications that have CRUD operations. I thought it would be great to immediately generate source code for such applications depending on the data model (entity) that we would like to manage. In the end, I made a web application that creates other mini web applications based on CRUD operations. We are not talking about a website builder. It is more of a source code constructor (back-end and front-end) for mini-sites of a certain type. After registering in my web project, you have the opportunity to create your own mini web projects. I've written detailed documentation on exactly how to do this. I would really like to receive feedback on the use of my service. I'm waiting for you here: http://developerhelper.tishtech.ru/
