In Dagger 2, interface injection refers to the process of injecting dependencies into an interface rather than a concrete class. While interface injection is not the primary approach in Dagger 2 (constructor or field injection is typically used), it can be achieved with the help of the @BINDS annotation.

SpringBoot-MultiVersion 是一个为 Spring Boot 项目设计的接口版本管理工具的先前版本的部分源码。它允许在同一个项目中同时存在多个相同路径的接口，通过注解和优先级机制来控制注册和访问的接口版本，实现灵活的版本切换和接口覆盖。
