将 play 2.2 应用程序移植到 2.3.2 版本时出错 (Scala)

【问题标题】：Error on porting a play 2.2 application to 2.3.2 version (Scala)将 play 2.2 应用程序移植到 2.3.2 版本时出错 (Scala)
【发布时间】：2026-02-23 04:10:01
【问题描述】：

我正在将 Play 2.2 应用程序移植到 Play 2.3 应用程序 (Scala)。 为此，我将安全社交版本更改为支持 Play 2.3 的 master-SNAPSHOT。 但是在编译时在我的游戏控制台中遇到错误。

怎么了？

    【解决方案1】：

    在 2.1.4 和 master 之间，securesocial 发生了巨大的重构。

    整个插件系统已被删除以支持注入组件。 Identity 和 IdentityId 特征已被删除，现在 Actions 由您自己的类型参数化。

    UserService API 也发生了很大变化，从同步变为异步。

    文档目前仍在编写中。您必须查看 samples 以了解这一切如何结合在一起。

    @编辑

    关于视图模板： securesocial.controllers.ViewTemplates 现在是一个特征，您可以扩展它以覆盖相应的视图。那么您必须更改默认接线以引入您自己的视图提供程序。

    如果您查看 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 并在此处覆盖它：

      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 = ???
    }
  }

    当然我不建议直接实现它，正确的方法是创建

    class CustomViewTemplates extends ViewTemplates{
//...
}

    然后

    override lazy val viewTemplates = new CustomViewTemplates()

    ViewTemplates 的默认实现在securesocial.core.ViewTemplates.Default

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

    设计已更改为允许基于编译和运行时的依赖注入。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）

    【讨论】：

    • 我在 github 存储库上看到了示例，但它对我没有帮助，因为不要使用 ViewTemplates
    • 感谢您的回答。我的问题在于 ViewTemplates 特征的实现，我在 github 上的示例项目中没有看到任何示例。编译器给了我找不到隐式值的错误。
    • 我添加了指向 ViewTemplates 的默认实现的链接...见 github.com/jaliss/securesocial/blob/master/module-code/app/…
    • 我已经解决了 ViewTemplates 的问题，现在我在使用 Registry 导致的视图包上出现了三个错误。我希望完成今晚的迁移。谢谢
    • 上面讨论的问题很多，能不能说的更准确点？在 java 示例 github.com/jaliss/securesocial/blob/master/samples/java/demo/… 中演示了创建自定义运行时环境，但是 securesocial 控制器本身是用 scala 编写的，而您可以在 java 中编写视图模板（因为 ViemTemplates 特征实际上是一个接口）它可能不是最理想的，因为您需要返回 scala 类型。随时提出具体问题并在此处链接，我会尽力提供帮助
