Why would anyone build with this?

REASON 1

Study how MyBatis maps SQL queries to Java objects by reading the annotated source with Chinese explanations

REASON 2

Understand how database caching, session management, and query execution work inside a production Java library

REASON 3

Follow the README's package-by-package guide to navigate the MyBatis codebase systematically

REASON 4

Supplement formal Java study with a real-world open-source library that has explanatory comments already in place

Wtf does this do

This repository is a copy of the MyBatis source code with Chinese-language comments added throughout. MyBatis is a widely used Java library that helps applications talk to databases by mapping SQL queries to Java objects. The original source code has minimal inline documentation, so this project adds detailed Chinese annotations to each part of the codebase to help developers who prefer reading in Chinese understand how MyBatis works internally. The README, which is written entirely in Chinese, walks through the major internal packages of MyBatis one by one: logging, caching, parsing, type conversion, session management, query execution, and more. Each section names the relevant package and briefly explains what it does. This is essentially a reading guide meant to accompany the annotated source code. The project is aimed at developers who want to study how a mature database-access library is built from the inside out. It is not a standalone application and does not add new features to MyBatis. The value is entirely in the Chinese annotations layered on top of the existing code. To use it, you also need to import a companion parent module from the official MyBatis organization on GitHub.

Yoink these prompts

Prompt 1
I am reading the tuguangquan/mybatis annotated source and want to understand how the Executor package processes a SQL query. Walk me through the flow from session.selectList to the actual database call.
Prompt 2
Help me trace how MyBatis's caching layer in tuguangquan/mybatis decides whether to use the first-level or second-level cache for a query.
Prompt 3
I am learning Java database programming. Using the annotated MyBatis source, explain how TypeHandler converts between Java types and SQL column types.
