## What it is
A curated source-code reading roadmap for Java backend engineers, walking through JDK/JUC, Spring, SpringBoot, Netty, Kafka, and RocketMQ internals with analysis notes and diagrams. It is a documentation/notes repository rather than runnable software.

## Use cases
- learn how Spring IOC container and extension points work internally
- understand Netty's Reactor model and EventLoop pipeline
- study Kafka broker, producer, and consumer source code
- prepare for Java backend interviews on framework internals
- find a structured path to read JDK and JUC concurrency source code
- understand RocketMQ message storage and rebalance implementation

## When to choose
- you are a Java backend engineer wanting guided source-code study of mainstream frameworks
- you prefer Chinese-language notes with diagrams over raw code reading
- you want a learning order from JDK basics up to messaging systems

## When to avoid
- you need runnable code or a library to include in your project
- you want English-language documentation
- you need coverage of the latest framework versions or non-Java stacks

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation
- domain: tutorials, developer-tools, backend
- platform: jvm
- tags: source-code-analysis, java, spring, netty, kafka, rocketmq, juc, learning-notes, study-guide
