Spring Boot 2.X 最全课程代码
A companion code repo for a Chinese-language Spring Boot 2.x video course series, covering 42 lessons across topics like MyBatis, JPA, Redis, Elasticsearch, WebSocket, and Docker. It's a learning resource, not a library — each lesson is a standalone Maven project you run to follow along. Aimed squarely at Java developers learning the Spring ecosystem in Chinese.
The breadth of integrations covered in one place is genuinely useful — you get working examples of MyBatis (both annotation and XML modes), multi-datasource JPA, Thymeleaf, Quartz, ActiveMQ, and more without hunting across a dozen separate tutorials. Each lesson is a self-contained project, so you can clone one subfolder and have something runnable without untangling a monorepo. The dual MyBatis examples (annotation vs XML) side-by-side are a nice touch for understanding the tradeoffs. Test coverage is present in the early lessons, which is more than most tutorial repos bother with.
Abandoned since October 2022 and locked to Spring Boot 2.x, which hit end-of-life in November 2023 — Spring Boot 3.x is the current baseline and involves non-trivial migration work (Jakarta namespace change alone breaks most of these examples). The course links in the README are all dead. There are no instructions for setting up the required databases (MySQL, Redis, MongoDB, Elasticsearch) so a new learner will spend significant time just getting the environment working before touching any lesson code. The repo is essentially a read-only artifact of a paid course that no longer exists; if you hit a problem, there's nowhere to ask.
