Which one should I pick for a new project?

I can only answer questions about proxyee-down-org/proxyee-down or wuyouzhuguli/springall.

However, I can help you understand what each project is for, which may inform your decision:

proxyee-down-org/proxyee-down is a HTTP download tool with multi-connection chunked download support, built on Netty. Critically, the project is stale — last commit was 2 years ago, and the README states maintenance has been paused. The authors explicitly recommend their successor project written in Go+Flutter instead.

wuyouzhuguli/springall is a collection of Spring Boot examples/tutorials covering multiple topics: JdbcTemplate, MyBatis, Thymeleaf, Shiro authentication, multi-datasource configurations, etc. It appears to be an educational reference repository.

For a new project:

• If you need a download manager, neither of these is recommended. Proxyee-down is unmaintained; consider the Go/Flutter successor mentioned in its README.
• If you need Spring Boot reference examples, springall could serve as learning material, though you should verify the Spring Boot version matches your needs.

Could you clarify what type of project you're building? That would help me give more specific guidance about whether either repository is relevant.
