O czym będzie mowa? Poniżej kilka słów o temacie:

Yes, we did it! Over a year ago we met a monster – a legacy
Spring MVC application with 50% code duplication, no tests,
manual deployment and mysterious error reporting. Come and
see yourself how blood, sweat and tears have then turned
into a well-tested REST API, pleasant to use and develop.

After a year we have an interactive API documentation, informative
call statuses and error messages. We precisely track every
request through its entire lifecycle. Together with version
tracking on multiple nodes, this lets us spot any errors
really quickly.

Plus, we reduced the boilerplate needed to achieve all of this to
a single annotation for each API call – with the help of
AspectJ, MDC, custom filters, converters and more.
Obviously, we also introduced src/test/groovy, full of Spock
and rest-assured – which made our application “the most
rigid part of the infrastructure”, as per our customer.

Come to hear our story, share yours and let us know if we could do better!

Jacek Kunicki is a full stack software engineer and one of the numeorus CEOs at SoftwareMill – a great remote workplace with no bosses. He contributes to some open source projects (Spring Boot, swagger2raml, Codebrag) and, apart from programming, plays a lot with hardware (Arduino and others). Jacek hates boilerplate and loves automation of everything, so that he has less to do.

Michał Matłoka is a Java developer with experience in both Java EE and Spring technologies. He is an open source contrubutor, and a winner of the JBoss Community Recognition Award in 2013 for his contributions to ShrinkWrap. Michał is also a co-author of recently published book „Java EE 7 Development with WildFly”. Michał is currently one of the 30 CEOs at SoftwareMill, a fully distributed company with no main office and a completely flat organization structure.
