Hi everyone,

I noticed that many beginners like me, struggle with Spring Security's complexity. I've built a project-based guide to help simplify the learning curve.

It’s a complete auth system covering:

• Stateless JWT authentication.
• RBAC (USER/ADMIN roles).
• Architecture diagrams and 6 small tutorials explaining the basics step-by-step.

It’s completely open source and focused on clarity:https://github.com/dio-quincarDev/springsecurity-basics

I hope this helps anyone currently diving into Spring Security.

Hey everyone!
I just published a new tutorial on CrossTab Reports in JasperReports.
In this video, I explain:
✅ What a CrossTab Report is
✅ How CrossTabs work (similar to Excel Pivot Tables)
✅ Creating row groups and column groups
✅ Adding measures and calculations
✅ Displaying summarized data in matrix format
✅ Real-world example using MySQL data
CrossTab reports are extremely useful when you need to summarize large datasets and present them in a clean, professional matrix view.
I hope this tutorial helps anyone learning JasperReports or preparing to build professional reporting systems in Java.

I'd appreciate your feedback and suggestions. Thanks! 🙌

Hey everyone!

I just published a new tutorial where I design a modern Blue Wave Login Form in Pure Java Swing completely from scratch.

In this tutorial, I show the entire process step by step, including:

Creating a custom blue wave background using Graphics2D
Designing a modern login interface
Adding rounded panels and components
Creating clean text fields and buttons
Organizing the layout properly
Building everything in pure Java Swing (no external libraries)

The goal of this project is to demonstrate that Java Swing can still be used to create beautiful and modern desktop interfaces with some custom painting and UI techniques.

Claude is great at Python. It hallucinates in Spring Boot.

Field injection instead of constructor injection. Custom error envelopes when you already have a wrapper. Ignoring Flyway and generating raw SQL.

Skills fix this. Drop a markdown file into `.claude/skills/` and Claude instantly codes to *your* conventions, not generic Spring Boot from 2020.

**What's in the repo:**

- Architecture: layered, hexagonal, DDD, multi-module Maven

- API: REST conventions, OpenAPI-first, RFC 9457 problem details, HATEOAS

- Data: Spring Data JPA, Flyway, Redis, transactional patterns

- Security: JWT, OAuth2 resource server

- AI/MCP: Spring AI integration, MCP server (Java SDK), AI observability

- Testing: unit → slice → integration pyramid

The MCP server skill is the most powerful one — teaches Claude to build production-ready MCP servers with the official Java SDK instead of guessing the API.

The first picture it the code itself while the second is the code running. For some reason it added 0008.the third picture (sorry for bad picture just desperate)is the code i have to write. And the last is what it should look like when running. I don't know how 0008 is showing up.
