Intro to Database Migrations in Spring Boot 3 with Flyway

Database migration is an essential process in software development. It ensures that changes made to the database schema are correctly applied to all environments, including development, staging, and production. Spring Boot, a popular Java framework for web development, provides a useful tool for implementing database migrations called Flyway. Flyway is an open-source database migration tool that helps developers manage database schema changes effectively. It tracks changes and applies them to the database in a systematic way, preserving data integrity and consistency across all environments. In this video, we will look at how to integrate Flyway into a Spring Boot 3 application and use it to manage database migrations effectively. We will cover the basic concepts of Flyway, such as its configuration, the creation and execution of migration scripts, and database versioning. By the end of this article, you will have a solid understanding of how to use Flyway to manage database changes, ensuring that your application’s data remains accurate and consistent across all environments. 👉👉Grab the source (on github): https://github.com/wazooinc/spring-boot-3-migrations-with-flyway 🔗Grab My Other Products Available: - Build Your First Web Service API Using Java Spring Boot https://wazoowebbytes.gumroad.com/l/xomqa 🔗Resources & Links mentioned in this video: - Start.spring.io: https://start.spring.io - Flyway: https://flywaydb.org/ - Some SQL basics: https://www.w3schools.com/sql/default.asp 👋🏻Connect with me: Twitter: https://www.twitter.com/eyuzwa ===---=== Concepts ===---=== - Spring Boot - Database Migrations - Flyway - Rollbacks ===---=== Chapters ===---=== 0:00:00 - Introduction 0:00:12 - What are Database Migrations? 0:07:36 - Start.spring.io Project 0:08:49 - Opening Project in IDE 0:09:11 - Link the Spring Boot Blog Application 0:09:37 - Setting our Application Properties 0:11:29 - Setting up the Resources/db/migration folder 0:12:11 - First cut of our Post Model 0:12:41 - Creating the First Migration 0:14:13 - Running the First Migration 0:15:05 - Checking out the Database 0:16:06 - Changing the Post Object Model 0:16:57 - Adding another Migration 0:18:36 - Adding a Sequence for our Post @Id 0:19:34 - Add Post Sequence Migration 0:20:52 - Check Updated Database Schema 0:21:33 - Add Authority Model 0:22:29 - Create Authority Table Migration 0:23:10 - Add Account Model 0:24:27 - Create Account Table Migration 0:26:42 - Add @OneToMany relationship from Account to Post 0:27:55 - Add Migration for account_id in Post Table 0:28:37 - @ManyToMany relationship from Account to Authority 0:29:31 - Create Account_Authority Table Migration 0:30:39 - A brief discussion about Rollbacks 0:31:40 - Creating test Migrations to demonstrate Rollback 0:33:57 - Wrapping Up #java #springboot #springboottutorial
