在参加这个论坛之前,我仔细检查了一下:
# This is the main configuration file for the application.
# ~~~~~
# Secret key
# ~~~~~
# The secret key is used to secure cryptographics functions.
# If you deploy your application to several instances be sure to use the same key!
application.secret="*********************************"
# The application languages
# ~~~~~
application.langs="en"
# Global object class
# ~~~~~
# Define the Global object class for this application.
# Default to Global in the root package.

# You can declare as many datasources as you want.

db.mytestdb.pass="user1"

# Logger

# You can also configure logback (http://logback.qos.ch/), by providing a logger.xml file in the conf directory .
# Root logger:
logger.root=ERROR
# Logger used by the framework:
logger.play=INFO
# Logger provided to your application:
logger.application=DEBUG
我想这是关于你的URL检查其他答案并修复它:
您是否尝试过像这样从url中删除user:password
db.mytestdb.url="jdbc:mysql://localhost:3306/mytestdb"
db.mytestdb.driver=com.mysql.jdbc.Driver
db.mytestdb.user="user1"
db.mytestdb.pass="user1"
是memcached问题没有启动。现在,我通过启动memcached使其工作。向我们展示您对此数据库的配置,整个数据库,仅将密码更改为
***
,而不更改任何其他内容。添加了配置文件,并进行了一些小的更改(用户、密码和数据库名称),您是否尝试使用本地主机而不是127.0.0.1
。也许它来自MySQL配置()中的绑定地址。@nico_ekito:127.0.0.1版本的Ubuntu10.04是如何工作的。使用localhost对我来说似乎很奇怪,但是让我试试,我会告诉你的。@nico_ekito:没有改变,得到相同的错误。val appDependencies=Seq(“mysql”%”mysql connector java“%”5.1.18、“org.hibernate”%”hibernate entitymanager“%”3.6.9.Final、“org.apache.httpcomponents”%”httpclient“%”4.1.3“,“com.github.mumoshu”%%“play2 memcached”%%“0.2.1-SNAPSHOT”)它已经在那里了。(如果我没记错的话,这就是你在链接中提到的内容)。我已经说过在Ubuntu 10.04上一切都处于工作状态。:(不:我指的是你的db.mytestdb.url=”mysql://user1:user1@127.0.0.1…”
将其切换到db.mytestdb.url=”jdbc:mysql://localhost/mytestdb?characterEncoding=UTF-8“
(url中没有凭据的jdbc)这样做了,但仍然不起作用。我记得在10.04上我用Sun JDK运行,在12.04上我打开了JDK。这有什么区别吗?
