## 多次使用不同的 `prefix` 包含同一个路由器 { #include-the-same-router-multiple-times-with-different-prefix }

你也可以在*同一*路由器上使用不同的前缀来多次使用 `.include_router()`。

在有些场景这可能有用，例如以不同的前缀公开同一个的 API，比方说 `/api/v1` 和 `/api/latest`。

这是一个你可能并不真正需要的高级用法，但万一你有需要了就能够用上。

## 在另一个 `APIRouter` 中包含一个 `APIRouter` { #include-an-apirouter-in-another }

 * The packaging type determines the structure of the project's output and how Maven will treat the resulting artifact.</p>
 *
 * <p>Common packaging types include {@code jar}, {@code war}, {@code pom}, {@code maven-plugin}, {@code ear}, and others.
 * These types influence various aspects of the build lifecycle, such as which plugins are executed and how dependencies are managed.</p>
