## What it is
A minimal, educational reimplementation of the Spring IoC container written in Java, built step-by-step with git tags mirroring Spring's design. It supports singleton beans with property and dependency injection, XML configuration, and AspectJ-style AOP with interface and class proxying.

## Use cases
- learn how Spring's IoC container works internally
- study a simplified Spring source code instead of the full framework
- understand dependency injection and bean lifecycle implementation
- learn how AOP proxies are built in Java
- follow a step-by-step tutorial for building a mini Spring
- teach framework design with a small readable codebase

## When to choose
- you want to read a small, readable codebase to understand Spring's core design
- you are learning dependency injection and AOP concepts hands-on
- you want to follow milestone git tags as a guided learning path

## When to avoid
- you need a production-ready dependency injection container
- you need full Spring features like transactions, web MVC, or Spring Boot integration
- you need active maintenance or long-term support

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: middleware, developer-tools
- domain: developer-tools, tutorials, programming-languages
- platform: jvm
- tags: ioc-container, dependency-injection, aop, spring-clone, educational, xml-configuration, aspectj
