application.conf 中的数据库属性：
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 文件包含行
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0")
Build.sbt 包含
lazy val myProject = (project in file("."))
.enablePlugins(PlayJava, PlayEbean)
有没有人遇到过这个问题。有人可以帮忙吗？
根据文档，插件版本应该是3.0.0，试试这个：
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "3.0.0")
还有 application.conf:
ebean.default = ["models.*"]
在play.db{}部分，应该是这样的：
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
}
}
在db{}部分，应该是这样的：
db {
default.driver=com.mysql.jdbc.Driver
default.url="jdbc:mysql://localhost:3306/dev"
default.username=root
default.password="Pa55word"
}
