我刚刚将我的操作系统从 Ubuntu 10.04 重新安装到 12.04，并且我在 ubuntu 10.04 上使用 play 2.0.1，在 10.04 上一切正常，但是现在使用相同的 play 2.0.1 事情搞砸了，现在每次我运行命令play "run 80"服务器启动，但是当我点击我的应用程序的索引页面时，它给了我以下异常：

[error] application - 

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

在来到这个论坛之前，我仔细检查了：

  1. mysql 正在运行。
  2. 用户具有足够的权限（通过登录该用户并在 bash 终端内的该数据库上运行一些选择命令）。
  3. 我的项目编译成功。

配置文件有一些小的改动：

# 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

您是否尝试过像这样从 url 中删除用户：密码？

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

这是没有启动的memcached问题。现在我通过启动 memcached 让它工作了。
