无法连接到db - PlayFramework + Ebean

Question

关于同样的错误，有很多问题，但这些答案并没有帮助我。

错误是：

CompletionException: javax.persistence.PersistenceException:默认的EbeanServer还没有定义？这通常是通过ebean.datasource.default属性设置的。否则，应该通过registerServer()以编程方式注册

引发此错误的代码：

public Result newuser() {
    Form<UserAuth> userform = formFactory.form(UserAuth.class).bindFromRequest();
    if(userform.hasErrors()) {
        return landing();
    }

    userform.get().save();
    flash("success", "User " + userform.get().login + " has been added");
    return landing();
}

build.sbt：

version := "1.0-SNAPSHOT" 
lazy val root = (project in file(".")).enablePlugins(PlayJava, PlayEbean)
scalaVersion := "2.11.7"
libraryDependencies ++= Seq(
javaJdbc,
cache,
javaWs,
evolutions,
"com.adrianhurt" %% "play-bootstrap" % "1.1-P25-B3",
"mysql" % "mysql-connector-java" % "5.1.21"
)

plugins.sbt：

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.5.10")
addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.1.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "3.0.2")

application.conf：

play.evolutions {
   #db.default.enabled = false
}

play.db {
 config = "db"
 default = "typobank"

 prototype {
 # Sets a fixed JDBC connection pool size of 50
 #hikaricp.minimumIdle = 50
 #hikaricp.maximumPoolSize = 50
 pool = "default"
 driver = com.mysql.jdbc.Driver
 user=user
 password=pass
 url="jdbc:mysql://localhost/typobank"

 hikaricp {
  #connectionTestQuery = "SELECT 1"
 }
 }
 }
 db {
    db.default.driver=com.mysql.jdbc.Driver
    db.default.url="jdbc:mysql://localhost/typobank?characterEncoding=UTF-8"
    db.default.username=hiddenuser
    db.default.password=pass
    ebean.default=["models.*"]
 }

Answer 1

这是难以置信的，但在扔掉默认配置垃圾，我已经让所有的工作！

这里使用的是纯配置：

play.crypto.secret = "changeme"

play.i18n.langs = [ "en" ]

db.default.driver=com.mysql.jdbc.Driver
db.default.url="jdbc:mysql://localhost/typobank?characterEncoding=UTF-8"
db.default.username=hiddenuser
db.default.password=pass

ebean.default=["models.*"]

Answer 2

我觉得应该够像这样的application.conf了：

db {
    default.driver=com.mysql.jdbc.Driver
    default.url="mysql://hiddenuser:pass@localhost/typobank?characterEncoding=UTF-8"
    default.username=hiddenuser
    default.password=pass
}
ebean.default=["models.*"]

更新：我尝试了这个修复，但这会在启动时引发异常：

Answer 3

你的

db {
  db.default...
}

计算结果为db.db.default，这就是为什么没有检测到它。这首先是主要原因。一定是

db {
  default.driver=com.mysql.jdbc.Driver
  default.url="jdbc:mysql://localhost/typobank?characterEncoding=UTF-8"
  default.username=hiddenuser
  default.password=pass
}
