What each one is
JustAuth
JustAuth is a Java library that lets an application offer "log in with another service" buttons, such as GitHub, Google, WeChat or Alipay, without writing each provider's login SDK from scratch. The README says it supports dozens of platforms and provides a simple API for building the authorization URL and handling the callback. Its documentation is mainly in Chinese.
Spring Boot Demo
This is a set of runnable example projects for learning Spring Boot, the Java framework for building server applications. The README says it contains 66 integration demos, 55 of which are finished, covering topics such as logging, template engines, ORMs, Redis caching, scheduled tasks, message queues, and Docker. Each module is a separate small project you can open and run on its own.
Best for
JustAuth
- Java developers adding social or third-party login to a web backend
- Teams that need to support several Chinese platforms such as WeChat, Alipay, Gitee or DingTalk
- Developers who want to add a custom OAuth provider through the documented extension mechanism
Spring Boot Demo
- Java developers who want to learn how Spring Boot features fit together
- Students following a hands-on Spring Boot tutorial
- Developers looking for a working example of a specific integration, such as MyBatis or Redis
- Teams comparing ORM or task-scheduling options side by side
Strengths
JustAuth
- The README shows a short, consistent API across many providers
- Supports a broad list of platforms, including many Chinese services
- Lets developers plug in their own HTTP client (hutool, httpclient or okhttp are shown)
Spring Boot Demo
- Covers many common Spring Boot integrations in one place
- Each module is organized by topic, so you can study one feature at a time
- Has a large community following, with about 34,000 stars on GitHub
Not ideal for
JustAuth
- Non-Java projects, since the library is written for Java and the README only shows Java examples
- Teams that need only one provider and prefer that provider's official SDK
- Readers who need English-language documentation, because the README and guide are primarily in Chinese
Spring Boot Demo
- People new to Java with no Spring experience, since the README assumes familiarity with Maven and IntelliJ IDEA
- Anyone who needs a production-ready application template, because the README describes it as a learning project
- Users who want the newest Spring Boot version, since the master branch is based on Spring Boot 2.1.0 and the 1.5.x branch is no longer maintained
Trade-offs
JustAuth
- Documentation and community discussion are mostly in Chinese, which may slow English-speaking users
- The README warns that snapshot builds are not stable and should not be used in production, so you must pin a stable release
- Provider-specific behavior and credentials still need to be configured and tested for each platform
Spring Boot Demo
- Built on Spring Boot 2.1.0, which is old compared with current releases
- The README says the 1.5.x branch is no longer maintained, and the README is written mainly in Chinese, with an English version linked separately
- Some modules need extra setup, such as initializing database data first, so not every demo runs immediately
