## What it is
A personal study repository documenting the author's Java security learning journey, from fundamentals like reflection and dynamic proxies to advanced topics like JNDI injection, deserialization, and memory webshells. It is a collection of informal notes with curated links to authoritative references rather than a structured tutorial.

## Use cases
- learn java deserialization vulnerabilities
- study jndi injection attack chains
- understand java reflection and dynamic proxies for exploitation
- prepare for java code audit interviews
- learn how memory webshells work in tomcat
- find java security learning resources and references
- study xxe and fast vulnerabilities

## When to choose
- you are learning Java security from scratch and want a curated path with references
- you want Chinese-language notes on Java deserialization and JNDI injection
- you need a study index linking to JVM specs, OWASP cheat sheets, and gadget chain writeups

## When to avoid
- you need a structured, polished course with consistent depth
- you want runnable exploit tooling rather than notes and links
- you need production security libraries or scanners

## Facets
- artifact type: learning-resource
- maturity: active
- function: security, penetration-testing, reverse-engineering, developer-tools
- domain: security, penetration-testing, tutorials
- platform: jvm, cross-platform
- tags: java-security, deserialization, jndi-injection, xxe, memory-webshell, code-audit, study-notes, vulnerability-analysis
