Upgrading to Spring Boot 3 Using Spring Boot Migrator

Even though the upgrade process for Spring Boot 3 is pretty straightforward - in case you need to migrate a more than moderately complex project (or several thereof), upgrading Spring Boot applications indeed can become quite tedious and error-prone, too. To alleviate this potential problem, and in order to automate the Spring Boot upgrade process, there's Spring Boot Migrator. Based on the terrific OpenRewrite toolkit for automated large-scale refactoring efforts, Spring Boot Migrator provides you with recipes for migrating both Spring Boot 2.7.x ...

Spring Boot 3, Spring Security 6, and Angular 15

Spring Boot is frequently used for business applications conjunction with Angular, with Spring Boot providing REST API endpoints and an Angular app delivering a user front-end on top of those endpoints. To help you get started with that kind of setup, particularly when it comes to the subjects of authentication and authorization and how to keep user data secure between the components involved in such an architecture, these GitHub projects can be quite helpful. All of those support the most recent versions ...

Schematic – A Database Management UI for Spring Boot

Out of my own need for an embedded database management tool for Spring Boot web applications, similar to the H2 Console, but for non-embedded databases, I've created Schematic - a database management UI for Spring Boot. Specifically, for the Workshops.DE Spring Boot course, some time ago we had decided to replace a development-time, embedded H2 database (and the console application that comes with it) with a more realistic (in that it brings our code closer to an assumed dev / prod parity, ...

Just – A Command Line Toolkit for Spring Boot Applications

In December last year, freelance software consultant Maciej Walkowiak, who also is the lead developer of Spring Cloud AWS, released just, a command-line toolkit for developing Spring Boot applications. I've been using just since then and I'm extremely happy with this tool and how it has improved my development experience with Spring Boot. Although Spring Boot already provides a more than decent developer experience - especially when it comes to getting up and running quickly and integrating technologies and data sources - compared ...

Inheriting Properties for Lombok @Builders and JPA Entities

Lombok is one of those helpful developer tools for the Java language ecosystem that streamline (or even do away with entirely) the more tedious and mundane tasks in software development. Lombok in particular vastly reduces the boilerplate code Java developers have to write by providing annotations that have code for common structures and patterns such as constructors, getters and setters, and builders automatically generated. While tremendously helpful, sometimes edge cases can occur when working with theses kinds of abstractions and as a ...

spring-dotenv: Using .env Files With Spring Applications

spring-dotenv, which in turn is based on dotenv-java is a library that enables Spring applications to access and use environment variables from .env files. .env files are a convention that enables us to store environment variables locally per directory / project instead of either doing so system-wide or in an ad-hoc manner (e.g., using the export shell command), thus allowing use to more strictly follow the storing config in the environment principle from The Twelve-Factor App in Spring (Boot) applications.

Bootify: Rapid Prototyping for Spring Boot

Bootify is a rapid prototyping and code generation tool for Spring Boot that aims at improving developer experience for when getting started with a new Spring Boot application. While of course there is Spring Initializr, which serves a similar purpose, Bootify not just generates a minimal Spring Boot application with the desired dependencies but, on top of that and amongst other features, also adds database schema and model generation, REST API and CRUD capabilities, and front-end code generation. With those features, Bootify is ...
