Silhouette 4 and Guice Bindings

[Aaron Patzer]

Off the https://github.com/mohiva/play-silhouette-angular-seed/tree/master build which relied on "com.mohiva" %% "play-silhouette" % "4.0.0-BETA4" I am running into binding issues.

class SilhouetteModule extends AbstractModule with ScalaModule {

 def configure() {
...
 bind[DelegableAuthInfoDAO[PasswordInfo]].to[PasswordInfoDAO]
 bind[DelegableAuthInfoDAO[OAuth1Info]].to[OAuth1InfoDAO]
 bind[DelegableAuthInfoDAO[OAuth2Info]].to[OAuth2InfoDAO]
 bind[DelegableAuthInfoDAO[OpenIDInfo]].to[OpenIDInfoDAO]
...

Guice seems to always bring in PersistenceModule, then tells me that a binding to "DelegableAuthInfoDAO was already configured" There is no problem at all in Silhouette 3 with the same code. How does one override the PersistenceModule bindings with their own real (not in memory) persistence in Silhouette 4?

This is the exact error off of silhouette master. You can see my forked code at https://github.com/apatzer/play-silhouette-angular-slick-seed

Solved.

Until 4.0_BETA5 is out, add the following to your application.conf

play.modules.disabled += "com.mohiva.play.silhouette.persistence.memory.modules.PersistenceModule"

Hello Aaron,

this is one solution. But if you do not use the memory module then it's not necessary to import it as dependency into your application.

So another solution would be to remove the following line from your build.sbt.

"com.mohiva" %% "play-silhouette-persistence-memory" % "4.0.0-BETA4"

Best regards,
