Question

出现以下错误：

ConfigurationException：Guice配置错误：

1）在play.db.ebean.EbeanPlugin中找不到合适的构造函数。类必须有一个（也是唯一一个）使用@Inject注释的构造函数或一个非私有的零参数构造函数。     at play.db.ebean.EbeanPlugin.class（EbeanPlugin.java:23）     找到play.db.ebean.EbeanPlugin

1错误

任何人都可以帮助我解决这个问题我是Playframe的新手，并且无法真正解决这个问题。

    addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.1.0")

    // Play Ebean support, to enable, uncomment this line, and enable in your build.sbt using

    // Play enhancer, regardless of whether the line above is commented out or not.
    addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0")

您的类没有一个（且只有一个）使用@Inject注释的构造函数或一个非私有的零参数构造函数

尝试添加非私有的零参数构造函数，例如

public Bar() {}

无法在play.db.ebean.EbeanPlugin中找到合适的构造函数，如何解决此问题？
