db Eigenschaften in application.conf:

default.driver=net.sourceforge.jtds.jdbc.Driver 
    default.url="jdbc:jtds:sqlserver://192.169.81.19/CKSCore_Dev1;instance=SQLEXPRESS" 
    default.user=ep_dev 
    default.password="ip4@123" 
    ebean.default.databasePlatform=com.avaje.ebean.config.dbplatform.MsSqlServer2005Platform 
    ebean.default="models.*" 

Plugins.sbt Datei enthält Zeile

addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0")  

Build.sbt enthält

lazy val myProject = (project in file(".")) 
    .enablePlugins(PlayJava, PlayEbean) 

Hat jemand Gesicht dieses Problems. Kann mir jemand helfen?

Answer 1

Gemäß der Dokumentation, die Plugin-Version 3.0.0 sein sollte, versuchen Sie dies:

addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "3.0.0") 

Und auch in application.conf:

ebean.default = ["models.*"] 

In play.db {} Abschnitt, es sollte so aussehen:

play.db { 
    # The combination of these two settings results in "db.default" as the 
    # default JDBC pool: 
    config = "db" 
    default = "default" 

    # Play uses HikariCP as the default connection pool. You can override 
    # settings by changing the prototype: 
    prototype { 
    # Sets a fixed JDBC connection pool size of 50 
    #hikaricp.minimumIdle = 50 
    #hikaricp.maximumPoolSize = 50 
    } 
} 

In db {} Abschnitt, so sein sollte:

db { 
    default.driver=com.mysql.jdbc.Driver 
    default.url="jdbc:mysql://localhost:3306/dev" 
    default.username=root 
    default.password="Pa55word" 
}
