Using Maven Failsafe With Spring Boot

Maven Failsafe is a Maven plugin designed to be used in conjunction with the Maven Surefire Plugin. While the former plugin is intended for running integration tests the latter's purpose is to run unit tests. These plugins are tremendously useful for partitioning tests in Maven-based Java applications in order to make tests and builds run faster. When recently using Maven Failsafe with a Spring Boot application, though, I encountered a somewhat gnarly problem. Running mvn verify caused this error for all of the ... Read more

A New Name for Our Upcoming Ebook: Stratospheric – From Zero to Production with Spring Boot and AWS

A few weeks ago I announced that together with fellow software developers and tech bloggers Tom Hombergs and Philip Riecks I have been working on a new project called AWS 101 for a few months now. To recap, the basic idea behind that project is to provide software developers and businesses with basic templates, recipes, building blocks, and overall best practices for developing, deploying, and running a Spring Boot application on Amazon Web Services (AWS). Since the "AWS 101" moniker was a bit ... Read more

So far and for the most part, we've been flying under the radar (the project is developed in the open though, see below) but the time has come to give you a little information about what to expect from this. The basic idea behind AWS 101 is to provide software developers and businesses with basic templates, ... Read more

HTTP and REST Standards, Protocols and Headers for More Secure and More Robust Applications

Standards.REST is a website that helps you create better, more robust HTTP- and REST-based applications by providing an overview of existing, proven standards that allow you to build on existing solutions rather than re-invent the wheel yourself. The list of standards mentioned includes OAuth 2.0, the HTTP Caching standard and Application-Level Profile Semantics (ALPS), which - among others - is used extensively in Spring Data REST and Spring HATEOAS. On a closely related note, Stefan Judis published an article on HTTP headers ... Read more

Running A Local Angular Development Environment Behind A Spring Cloud Gateway Service

Having multiple microservices running behind a reverse proxy / API gateway in lieu of a single monolithic back-end application is a common pattern these days. With such an architecture it often comes in handy to have an Angular application that serves as a front-end for such a modularised back-end be served from behind a reverse proxy running locally as well in order to treat it is if it were running on the same host and port as the back-end. Not only will ... Read more

“Paging with Spring Boot” by Tom Hombergs: A Guide to Paging and Pagination in Spring-based Web Applications

In his article Paging with Spring Boot software engineer Tom Hombergs (a former fellow student) provides an in-depth explanation of paging and pagination concepts and how to implement those in web applications with Spring Data and its Pageable interface. The article covers aspects such as sorting, usage with Spring Data repositories and testing. It's a useful reference for iteratively retrieving and displaying a larger amount of items from a database in a Spring Boot and Spring Data context in an efficient manner. There's ... Read more
