Spring Boot 2 - CRUD - Part 2 | Spring Boot+MVC+JPA+H2+Thymeleaf+Bootstrap+Junit5 | Code Journal

Hello, everyone, and welcome to the video Series - Built it with Spring Boot.

This video series tries to build Java applications using Spring Boot, which has become de-facto standard for building applications in Java world. It makes it easy to create stand-alone, production-grade Spring based Applications. It cuts down on a lot of boilerplate code, and its sensible defaults for configurations allows to build applications in super quick time

The project we are building here is a Spring Boot Web application that demonstrates CRUD operations. The application allows to manage student information, by a paginated student list, adding a new student, viewing student information, editing them, and deleting them. The application also has Login/Logout feature.

The technology stack consists of - Spring Boot, Undertow, Spring MVC, Java Persistence API, Hibernate, Thymeleaf, Bootstrap CSS, Spring Security, and Junit5.

This video is Part 2 of 5, in which we will configure the H2 database, and create our JPA repositories which will make calls to the database via Hibernate. We will also, write JUnit 5 tests for the Repository classes using @DataJpaTest.

Hello Sir, why in the method you don't pass the created id in the first line when creating the new Student object? I can see on your webiste and there you passed this id to the Student constructor. So how can this test be correct?

Hi Code Journal, Great videos, I watched and followed along with you. Ran into a small issue when experimenting.

I went back to reconfigure the mem database to file:~/test_db and it seems that the tables aren't created, what is creating the tables on the memory database?

If I load the app without auto creating some items and with using the h2 console to add the tables/column it works afterwards, but what am I missing to auto create the tables?

some error output: 2021-10-15 12:53:50.117 ERROR 13636 --- [ restartedMain] : Table "STUDENT" not found; SQL statement:
