## What it is
mini-spring is a heavily simplified reimplementation of the Spring framework in Java, preserving core features like IoC, AOP, bean lifecycle, and application context. It is designed as an educational project to help developers understand Spring's source code and core principles.

## Use cases
- learn how spring ioc container works internally
- understand spring aop and dynamic proxies
- study spring bean lifecycle and application context
- prepare for spring framework source code interviews
- build a mini dependency injection framework from scratch
- learn spring core principles with simplified code

## When to choose
- you want to deeply understand Spring's internals rather than just use it
- you prefer learning by reading and building a minimal framework step by step
- you are preparing for Java backend interviews covering Spring principles

## When to avoid
- you need a production-ready dependency injection or web framework
- you want Spring Boot auto-configuration, Spring MVC, or the full Spring ecosystem
- you need community support, extensive documentation, or long-term maintenance

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools
- domain: developer-tools, tutorials, programming-languages
- platform: jvm
- tags: spring, ioc, aop, dependency-injection, educational, source-code-study, java
