玩转子项目路线

Question

我有戏！ 2.5.3 project with one subproject（有自己的路线）。在主路由文件中，子项目的路由定义如下：

->        /api                         api.Routes
GET       /assets/*file                controllers.Assets.at(path="/public", file)

和api.routes文件如下：

GET      /v1/permissions/roles         controllers.api.PermissionsController.roles

因此获得角色的 URL 将是 /api/v1/permissions/roles。

当我运行根项目（依赖于两个子项目）时一切正常，但是当运行分别连接每个子项目时，找不到路由。我尝试在构建过程中将主路由文件复制到已构建子项目的 conf 文件夹中，但是没有用。

我找到的唯一解决方案是在 application.conf 中添加 play.http.router = "api.Routes"，但是路由 "looses" 它的 /api 前缀（即：api 路由是/v1/permissions/roles)

所以我的问题是：是否可以有一个带有路由的子项目，并且这些路由在运行根项目和每个运行时是相同的子项目分开？

如果可能的话，它在文档中的任何地方吗？

编辑：

build.sbt 用于根项目

我不认为你可以这样做，项目是二进制绑定的，我的意思是所有模块 jar 都必须在 class 路径中（根据 build.sbt）。你不能运行他们单独。

我希望您正在寻找的是微服务之类的东西。如果是这样，您需要了解微服务带来的成本。一旦决定使用微服务，您可以看看 Lagom Framework (https://www.lightbend.com/lagom)
