Question

我目前与 play-pac4j 库以及 Play Framework 2.5 结合起来。

注释：

@RequiresAuthentication(clientName = "FacebookClient")

我的控制器方法中的

会导致此堆栈跟踪：

com.google.inject.internal.ConstructorBindingImpl.create（ConstructorBindingImpl.java:99）在com.google.inject.internal.InjectorImpl.createUninitializedBinding（InjectorImpl.java:658

这是我用于依赖的build.sbt的片段：

libraryDependencies ++= Seq(
      "org.pac4j" % "play-pac4j" % "2.1.0",
      "org.pac4j" % "pac4j" % "1.8.7",
      "org.pac4j" % "pac4j-http" % "1.8.7",
      "org.pac4j" % "pac4j-cas" % "1.8.7",
      "org.pac4j" % "pac4j-openid" % "1.8.7",
      "org.pac4j" % "pac4j-oauth" % "1.8.7",
      "org.pac4j" % "pac4j-saml" % "1.8.7",
      "org.pac4j" % "pac4j-oidc" % "1.8.7",
      "org.pac4j" % "pac4j-gae" % "1.8.7",

      "org.pac4j" % "pac4j-mongo" % "1.8.7",
      "org.pac4j" % "pac4j-stormpath" % "1.8.7")

我的SecurityModule类：

public class SecurityModule extends AbstractModule {
protected void configure() {
    FacebookClient facebookClient = new FacebookClient("KEY", "SECRET_KEY");
    Clients clients = new Clients("http://localhost:9000/callback",facebookClient);
    Config config = new Config(clients);
    config.addAuthorizer("admin",new RequireAnyRoleAuthorizer("ROLE_ADMIN"));
    bind(Config.class).toInstance(config);

}

}

我的项目中提供了play.libs.F包。 Eclipse screenshot

我基本上试着想到的一切。现在我只想在路由配置文件中为我的一个地址启用简单的身份验证。我按照这里发布的说明进行了跟踪：https://github.com/pac4j/play-pac4j。任何帮助和提示将不胜感激。

查看问题页面here，pac4j与Play 2.5不兼容。听起来像pac4j正在使用的2.5中缺少一些API。你在堆栈交易中看到的是Play 2.5删除scala f.Function，f.Function0类等，而不是Java8 java.util.function.*类型。那个here上有doco。

简而言之，要么等待pac4j 2.3.0出来，要么回到Play 2.4。

Play-pac4j与Play 2.5：@RequiresAuthentication注释导致stacktrace
