In plain English

This is a Chinese-language deep-dive reference for Java developers who want to understand how popular frameworks and middleware actually work under the hood, not just how to use them, but what happens inside the code when you call their APIs. The project analyses the source code of widely-used Java tools: the Spring family (Spring core, Spring MVC, Spring Boot, Spring Cloud, Spring Security), MyBatis (a database access library), Netty (a networking framework), Dubbo (a remote procedure call system), Redis (a fast in-memory data store), and Tomcat (a web server). For each tool, there are written walkthroughs explaining concepts like dependency injection, transaction management, how SQL queries get processed, and how network connections are handled. You would use this if you are a Java backend developer who already knows how to use these tools but wants to understand why they behave the way they do, useful for debugging tricky bugs, performing well in technical interviews, or growing from an intermediate to an advanced level. The explanations are written in Chinese. No setup or code is required to read the material.

Copy-paste prompts

Prompt 1
I'm debugging a Spring transaction issue in production. Walk me through how Spring's transaction management works internally using source-code-hunter.
Prompt 2
Help me understand how MyBatis maps SQL queries to Java objects by explaining the source code flow.
Prompt 3
Explain how Netty handles concurrent network connections and why it's faster than traditional blocking I/O.
Prompt 4
I want to understand how Dubbo's RPC mechanism works. What happens when I call a remote service?
Prompt 5
Use source-code-hunter to explain how Spring Boot auto-configuration discovers and wires beans automatically.
