Question

我会尝试找到问题，但我不能。

我会尝试将我的应用程序部署到CloudBees平台。在我的application.conf文件中，我设置了params：

###############################################################
# Production config ###########################################
###############################################################
%production.application.mode=prod
%production.jpa.ddl=create
%production.db.url="jdbc:mysql:"${MYSQL_URL_EASYBOOKDB}
%production.db.driver=com.mysql.jdbc.Driver
%production.db.user=${MYSQL_USERNAME_EASYBOOKDB}
%production.db.pass=${MYSQL_PASSWORD_EASYBOOKDB}

之前，我将我的应用与db

相关联

bees app:bind -db easybook -a zolt/easybook -as easybookdb

我已经为playframework安装了cloudbees模块。我部署了我的应用程序，如：

play bees:app:deploy --%production

得到答案：

upload complete, response=<?xml version="1.0" encoding="UTF-8"?>
<ApplicationDeployArchiveResponse>
<id>zolt/easybook</id>
<url>http://easybook.zolt.cloudbees.net</url>
</ApplicationDeployArchiveResponse>
Application zolt/easybook deployed: http://easybook.zolt.cloudbees.net

之后，我转到链接http://easybook.zolt.cloudbees.net并查看tomcat错误页面...

在日志中我看到了栈跟踪：

如果我尝试通过MysqWorkbench连接数据库，那一切都很好...... 我做错了什么？

Answer 1

我认为您没有以正确的方式将数据库与您的应用程序绑定。

根据数据库绑定正在运行的Play1 ClickStart。这些是步骤：

1.在application.conf你应该有这个：

db=java:comp/env/jdbc/mydb
jpa.dialect=org.hibernate.dialect.MySQL5Dialect

2.将应用程序绑定到数据库

$bees app:bind -a appName -db dbName -as mydb

3.重新部署应用程序

 bees app:deploy -a MY_APP -t tomcat7 myapp.war

有关Play1的官方文档为here。
