Choose this fork if your goal is learning and code reading. Choose upstream if you need current framework behavior, active maintenance, or a reliable foundation for new work.

Prefer this fork only if your goal is studying or teaching Spring internals in Chinese with added annotations. If you need an actively maintained framework base, current APIs, or production adoption, upstream is the better choice.

Choose this fork if your goal is education and code comprehension. Choose upstream if you need an up-to-date, production-oriented Spring Framework.

Prefer this fork only if you want a study-friendly or customized Spring base and can live without full upstream parity. For production adopters, upstream is the safer choice because this fork is far behind and appears to have removed core multipart functionality.

Choose the upstream Spring Framework unless you explicitly need this older 2020 snapshot or its local experiments. Adopt this fork only for archival, educational, or legacy-support reasons; it is too stale and too far from current upstream for normal production use.

Prefer this fork only if you explicitly need an older, documentation-rich Spring baseline and are willing to live with major upstream drift. For new development or active platform upgrades, upstream is the better choice.

Prefer upstream Spring unless you are explicitly maintaining a legacy 2012-era stack and need this fork's historical behavior; for new work, the fork is too stale and too far behind to be a sensible base.

Choose this fork if your goal is learning and documentation. Avoid it if you need an up-to-date, maintainable Spring Framework base for real application development.

Prefer this fork only if you specifically need its Jakarta EE 11-oriented cleanup or its removed legacy paths align with your deployment model. For most adopters, upstream Spring Framework is the safer default because this fork is stale and substantially diverged.
