我正在通过 Play Framework 2.0 开发一个 Web 应用程序。

因为我需要访问 DB2 数据库，所以我在应用程序的 application.conf 文件中添加了以下几行：

db.mydb.driver=com.ibm.db2.jcc.DB2Driver
db.mydb.url="jdbc:db2://host:port/databaseName"
db.mydb.user=user
db.mydb.password=pass
db.mydb.jndiName=databaseName

我成功连接到该数据库，但出现以下异常：

[info] play - datasource [jdbc:db2://host:port/databaseName] bound to JNDI as databaseName
[info] play - database [databaseName] connected at jdbc:db2://host:port/databaseName
[warn] application - play_evolutions table already existed
[error] application -

为了解决这个问题，我尝试禁用 Evolutions，在 application.conf 文件中设置以下行：

evolutions=disabled
evolutions.enable=false

但我总是得到上述例外。

谁可以帮我这个事？

谢谢

OK... Finally found out the origin of the problem...

Like I said I am using Play Framework 2.0 and was working in the forms tutorial project that comes with this version of Play...

As it turns out the command to disable Evolutions is neither:

evolutions=disabled evolution=disabled

... But rather:

evolutionplugin=disabled

Thanks
