Explore Spring Boot 3 and Spring 6 in-depth through building a full REST API with the framework:
Partner – Lightrun – NPI EA (cat=Spring)

We rely on other people’s code in our own work. Every day.
It might be the language you’re writing in, the framework you’re building on, or some esoteric piece of software that does one thing so well you never found the need to implement it yourself.
The problem is, of course, when things fall apart in production - debugging the implementation of a 3rd party library you have no intimate knowledge of is, to say the least, tricky.
Lightrun is a new kind of debugger.
It's one geared specifically towards real-life production environments. Using Lightrun, you can drill down into running applications, including 3rd party dependencies, with real-time logs, snapshots, and metrics.

Looking for the ideal Linux distro for running modern Spring apps in the cloud?
Meet Alpaquita Linux: lightweight, secure, and powerful enough to handle heavy workloads.
This distro is specifically designed for running Java apps. It builds upon Alpine and features significant enhancements to excel in high-density container environments while meeting enterprise-grade security standards.
Specifically, the container image size is ~30% smaller than standard options, and it consumes up to 30% less RAM:
Course – LSS – NPI EA (cat=Spring Security)

Yes, Spring Security can be complex, from the more advanced functionality within the Core to the deep OAuth support in the framework.
I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

Slow MySQL query performance is all too common. Of course it is. A good way to go is, naturally, a dedicated profiler that actually understands the ins and outs of MySQL.
The Jet Profiler was built for MySQL only, so it can do things like real-time query performance, focus on most used tables or most frequent queries, quickly identify performance issues and basically help you optimize your queries.
Critically, it has very minimal impact on your server's performance, with most of the profiling work done separately - so it needs no server changes, agents or separate services.
Basically, you install the desktop application, connect to your MySQL server, hit the record button, and you'll have results within minutes:
Partner – DBSchema – NPI EA (tag = SQL)

DbSchema is a super-flexible database designer, which can take you from designing the DB with your team all the way to safely deploying the schema.
The way it does all of that is by using a design model, a database-independent image of the schema, which can be shared in a team using GIT and compared or deployed on to any database.
And, of course, it can be heavily visual, allowing you to interact with the database using diagrams, visually compose queries, explore the data, generate random data, import data or build HTML5 database reports.

>> CHECK OUT THE COURSEBuilding a REST API is not a trivial task – from the high-level RESTful constraints down to the nitty-gritty of making everything work and work well.
Spring has made REST a first-class citizen and the platform has been maturing in leaps and bounds.
With this guide, my aim is to organize the mountains of information that are available on the subject and guide you through properly building an API.
The guide starts with the basics – bootstrapping the REST API, the Spring MVC Configuration, and basic customization.
It then dives into the more advanced areas of REST – such as error handling, pagination, documenting, and testing the API.
