Playframe 2.0.1：连接数据库总是失败

Question

我刚刚从Ubuntu 10.04到12.04重新安装了我的操作系统，我在Ubuntu 10.04上使用了play 2.0.1,10.04上一切正常，但是现在同样的play 2.0.1把事情搞砸了，现在每次我运行命令play运行80"服务器启动，但当我击中我的应用程序的索引页，它给我以下异常：

[error] application - 

! @6bh1b1h5g - Internal server error, for request [GET /] ->

在参加这个论坛之前，我仔细检查了一下：

1. mysql正在运行

配置文件有一些小改动：

# 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.
# global=Global

# Database configuration
# ~~~~~ 
# You can declare as many datasources as you want.
# By convention, the default datasource is named `default`
#

db.mytestdb.url="mysql://user1:user1@127.0.0.1:3306/mytestdb"
db.mytestdb.driver=com.mysql.jdbc.Driver
db.mytestdb.user="user1"
db.mytestdb.pass="user1"
db.mytestdb.jndiName=mytestdbDS

jpa.default=TESTmytestdb
jpa.TESTmytestdb=TESTmytestdb

# 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

Answer 1

是memcached问题没有启动。现在我通过启动memcached使它工作。

Answer 2

你试过像这样从url中删除user：密码吗？

db.mytestdb.url="jdbc:mysql://localhost:3306/mytestdb"
db.mytestdb.driver=com.mysql.jdbc.Driver
db.mytestdb.user="user1"
db.mytestdb.pass="user1"

Answer 3

我想这是关于你的URL检查其他答案并修复它：
