Spring Boot Framework - Internship tasks

This repository contains a base project for internship program at GlobalDatabase, each candidate for position of Junior Backend Developer must be able to develop all the tasks in the following lists. Fork it and bring it to the next level.

Workflow

1. Before starting this program you should know Java or another programming language at a level beginner, and understand syntax, variables, functions, algorithms, etc. If you have lacked in language understanding then start with https://www.learnjavaonline.org/
2. First milestone is to prove that you are ready for internship program
3. Before each milestone estimate each task in hours of work to understand how much time you need to achieve the finish, don't worry if your estimations are wrong because you don't have experience.
4. After each milestone or sequence of tasks create a merge request to your mentor to receive feedback, after code review you will have something to fix this will improve your coding skills
5. Be focused on tasks and ask questions when you don't understand something and you didn't find anything on Google ( googling is a base skill for developers)

2. Add validation for user registration or auth.
3. Modify the previously created endpoints so that you cannot add a product if you are not authenticated

Milestone 3

Working with algorithms and data structures

What will you learn

1. Work with spring mybatis
2. Work with spring data
3. Work with algorithms and data structures

Tasks

1. Add the ability to search for products by name
2. Add the ability to like a product - the user can like a product only once
3. Add the ability to dislike a product - the user can dislike a product only once

Milestone 4

Working with Documentation

What will you learn

Work with swagger

Milestone 5

Work with COPY Postgresql
