根因分析

两个或多个包直接或间接相互导入,创建了 Go 编译器无法解析的循环依赖。

English

Two or more packages import each other directly or indirectly, creating a circular dependency that Go's compiler cannot resolve.

解决方案

  1. Extract the shared types or interfaces into a third package that both A and B import
  2. Use dependency injection: pass interfaces from A to B instead of importing A directly in B

无效尝试

常见但无效的做法:

  1. Using a blank import (_ "package") to break the cycle 95% 失败

    Blank imports only trigger init() functions, they don't resolve the circular dependency in the type system.

  2. Moving all code into a single package 80% 失败

    Violates separation of concerns; makes the codebase monolithic and harder to maintain.

  3. Adding a new import that re-exports types from the cycle 90% 失败

    Creates a longer cycle or introduces a third package that still depends on the cycle.
