有我的配置： 

 db.default.driver=com.mysql.jdbc.Driver
 db.default.url="jdbc:mysql:root:play2test" //Cannot connect to database [default] -> play mark this line
 db.default.user=root
 db.default.pass=123456

我已经使用 MySql-workbench 创建了 play2test.mwb，我尝试了其他方式，例如： 

 db.default.driver="com.mysql.jdbc.Driver"
 db.default.url="jdbc:mysql:root:play2test" 
 db.default.user="root"
 db.default.pass="123456"

但总是会出现此错误：db 的类型为 STRING 而不是 OBJECT

在终端： 

[error] c.j.b.h.AbstractConnectionHook - Failed to obtain initial connection Sleeping for 0ms and trying again. Attempts left: 0. Exception: null
[error] application -

我试图取消评论 

ebean.default="models.*"

并添加了 sbt 依赖项： 

 "mysql" % "mysql-connector-java" % "5.1.21"

但它没有工作:((((那么我怎么能解决它:(。

对不起，如果我的英语不好

尝试以下方式：

   db.default.url="jdbc:mysql://your_server_address:3306/play2test" 
   db.default.driver="com.mysql.jdbc.Driver"
   db.default.user=root
   db.default.pass="123456"
   db.default.host=your_server_address

您的连接网址格式错误。尝试使用：

db.default.url="jdbc:mysql://localhost/play2test"

并确保在 /project/Build.scala 中设置产品依赖项，将 5.1.25 更改为 mysql 连接器的任何版本

val appDependencies = Seq(

"mysql" % "mysql-connector-java" % "5.1.25"

)

并且在同一个文件中，确保该行没有被注释

ebean.default="models.*"

网址应该类似于：

db.default.url="jdbc:mysql://your_server_address/play2test"
