Ebean和H2配置問題與Play框架2.5

我想用Play Framework版本2.5開發，並且我無法獲得正確的數據庫連接。我使用H2數據庫和Ebean插件3.0.2作爲ORM。根據Play Framework網站上的信息和您的許多帖子，我嘗試了幾個application.conf中的條目選項。請找到條目我的配置文件和錯誤跟蹤之下，並幫助我：Ebean和H2配置問題與Play框架2.5

 **Application.conf** 

     play.db { 
     # The combination of these two settings results in "db.default" as the 
     #default JDBC pool: 
     config = "db" 
     default = "default" 
     prototype { 
      # Sets a fixed JDBC connection pool size of 50 
      #hikaricp.minimumIdle = 50 
      #hikaricp.maximumPoolSize = 50 

       } 
     } 

    db { 
    default.hikaricp.dataSourceClassName = org.h2.jdbcx.JdbcDataSource 
    default.driver = org.h2.Driver 
    default.url = "jdbc:h2:mem:play" 
    default.username = sa 
    default.password = "" 
    ebean.default = ["models.*"] 
    #play.ebean.default.dataSource = default 

     default.logSql=true 
    } 
    **Plugins.sbt** 

    addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.5.10") 

    // Web plugins 
    addSbtPlugin("com.typesafe.sbt" % "sbt-coffeescript" % "1.0.0")

    addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % 

    "5.0.1") 

    **Build.sbt**

我曾與H2的配置，這是解決被添加dataSourceClassName相同的錯誤消息，但我曾嘗試使用默認爲Ebean的數據源沒有成功。謝謝！

ebean.default = ["models.*"]不是鑰匙db.default的成員，您必須將其放置在db之外。

根據您的日誌ebean認爲，這關鍵是另一個數據庫

play.api.Configuration$$anon$1: Configuration error[Cannot connect to 
    database [ebean]]

謝謝你這麼多Pedroct92，那是我的配置文件中的問題。用下面的變化，我的應用程序的工作：DB { default.driver = org.h2.Driver default.url = 「的jdbc：H2：MEM：玩」 default.username = SA default.password = 「」 } ebean.default =「models。*」 –
