尝试使用mysql 5.5连接播放时出错[重复]

Question

这是我的配置：

 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

我已经创建了play2test。mwb使用MySql workbench，我尝试了其他方法，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

在终端中：

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

我试图在

ebean.default="models.*"

并添加了sbt依赖项：

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

但它没有工作：（（（（所以我怎么能解决它：（。

如果我的英语不好

Answer 1

url应该类似于：

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

Answer 2

您的连接url格式错误。尝试使用：

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

并确保您在 /project/Build.scala设置了产品依赖关系，将5.1.25更改为您的mysql连接器的任何版本

val appDependencies = Seq(

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

)

在同一个文件中，确保这一行没有注释

ebean.default="models.*"

Answer 3

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
