Get list of all routes in play 2.5 in SCALA with DI

[Ivan Sebben]

Hi,

How can I retrive all routes of my play project? 

I try to inject in My controller the Router provider but have always thi problem:

CreationException: Unable to create injector, see the following errors: 1) Tried proxying services.ConfigUtils to support a circular dependency, but circular proxies are disabled. at Module.configure(Module.scala:14) (via modules: com.google.inject.util.Modules$OverrideModule -> Module) while locating services.ConfigUtils for parameter 0 at controllers.ApplicationController.<init>(ApplicationController.scala:16) at controllers.ApplicationController.class(ApplicationController.scala:16) while locating controllers.ApplicationController for parameter 3 at router.Routes.<init>(Routes.scala:35) while locating router.Routes while locating play.api.inject.RoutesProvider while locating play.api.routing.Router for parameter 0 at play.core.j.JavaRouterAdapter.<init>(JavaRouterAdapter.scala:17) while locating play.core.j.JavaRouterAdapter while locating play.routing.Router for parameter 2 at services.ConfigUtils.<init>(ConfigUtils.scala:30) at Module.configure(Module.scala:14) (via modules: com.google.inject.util.Modules$OverrideModule -> Module) while locating services.ConfigUtils

Hi Ivan,

This is a classic circular dependency issue. The router needs your controllers, your controller needs ConfigUtils, and ConfigUtils needs the router. Hence the circular dependency. In this case you could try injecting a Provider<Router> to break the cycle, and just make sure you don't need to get the router until after ConfigUtils is constructed.
