Question

我将Play 2.2应用程序移植到Play 2.3应用程序（Scala）。为此，我将安全的社交版本更改为支持Play 2.3的主-SNAPSHOT。但是在编译时会在我的播放控制台中遇到错误。

出了什么问题？

Answer 1

在2.1.4和master之间的secSecocial中有一个巨大的重构。

整个插件系统都被淘汰，有利于注入组件。已删除Identity和IdentityId特征，现在您自己的类型参数化了Actions。

UserService API也发生了很大的变化，从同步变为异步。

目前仍在处理文档。您必须查看samples以了解这一切是如何组合在一起的。

@edit

关于视图模板： securesocial.controllers.ViewTemplates现在是一个特性，您可以扩展它以覆盖相应的视图。然后你必须改变默认接线来介绍你自己的视图提供者。

如果查看Global中的示例，它会创建一个对象MyRuntimeEnvironment

object MyRuntimeEnvironment extends RuntimeEnvironment.Default[DemoUser] {
    override lazy val routes = new CustomRoutesService()
    override lazy val userService: InMemoryUserService = new InMemoryUserService()
    override lazy val eventListeners = List(new MyEventListener())
  }

您可以创建自己的ViewTemplate并在此处覆盖：

  object MyRuntimeEnvironment extends RuntimeEnvironment.Default[DemoUser] {
    override lazy val routes = new CustomRoutesService()
    override lazy val userService: InMemoryUserService = new InMemoryUserService()
    override lazy val eventListeners = List(new MyEventListener())
    override lazy val viewTemplates = new ViewTemplates{

      override def getLoginPage(form: Form[(String, String)], msg: Option[String])(implicit request: RequestHeader, lang: Lang): Html = ???

      override def getPasswordChangePage(form: Form[ChangeInfo])(implicit request: RequestHeader, lang: Lang): Html = ???

      override def getNotAuthorizedPage(implicit request: RequestHeader, lang: Lang): Html = ???

      override def getStartSignUpPage(form: Form[String])(implicit request: RequestHeader, lang: Lang): Html = ???

      override def getSignUpPage(form: Form[RegistrationInfo], token: String)(implicit request: RequestHeader, lang: Lang): Html = ???

      override def getResetPasswordPage(form: Form[(String, String)], token: String)(implicit request: RequestHeader, lang: Lang): Html = ???

      override def getStartResetPasswordPage(form: Form[String])(implicit request: RequestHeader, lang: Lang): Html = ???
    }
  }

当然我不建议在那里实际实现它，正确的方法是创建

class CustomViewTemplates extends ViewTemplates{
//...
}

然后

override lazy val viewTemplates = new CustomViewTemplates()

ViewTemplates的默认实现位于securesocial.core.ViewTemplates.Default

可以为每个“旧”插件（userService，authenticator store，IdGenerator，PasswordValidator，邮件模板等）使用相同的机制，实际列表实际上可以从securesocial.core.RuntimeEnvironment.Default

派生

设计已更改为允许基于编译和运行时的依赖项注入。它可能（不幸的是）必须再次使用play 2.4和play 3.0进行更改，这将使运行时DI成为框架的一等公民（同时仍然支持编译时注入）

将play 2.2应用程序移植到2.3.2版本（Scala）时出错
