org.apache.commons.dbcp.SQLNestedException（sql server 2008或者以上）

由 断了今生、忘了曾经 提交于 2019-12-11 18:12:58
我们使用java的jdbc连接数据时候，出现这种情况： org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Unknown server host name 'X.X.X.X.XX'.) 连接数据库的参数设置是： 报错的大致意思是，未知的主机host，意味着识别不了，这个时候从两个方面着手。 第一：用这个用户名，地址，密码，使用sqlserver studio工具，看是否正常登陆。 如果这个步骤没问题，说明是java的配置有问题。按照第二种情况 第二：检查连接参数，有些是需要1433端口（默认1433），地址：1433，注意是英文下的冒号。或者直接省略，不能用逗号或者其他连接符，。不然会报未知的host。 driverClassName=net.sourceforge.jtds.jdbc.Driver url=jdbc:jtds:sqlserver://111.111.111.111:1433;DatabaseName=XXXX username=XXX password=XXXXX 这样就ok了。我的项目是spring mvc框架的。 如有问题，希望指正并相互学习！ 来源： CSDN 作者： haors 链接： https://blog.csdn.net/qq

The same page hosted only loads correctly in IE8 & Chrome I'm new to galleria and jquery so please be gentle with me as I think I must be missing something very obvious.

Replacing the Host file in Java

由 只谈情不闲聊 提交于 2019-12-11 12:47:52
问题 So here's my code so far, yes I know it's pretty basic. But what I would Like to accomplish is to Replace the host file located in the System32\drivers\etc folder, the problem I am having in doing this is that I am getting an access denied error. How can I give the program access to make changes within the windows folder, also the class SaveURL just downloads the file and uses two strings to pass the name and download location through the function saveImage. How can I give myself access?

Find Host and Port in a Django Application

由 青春壹個敷衍的年華 提交于 2019-12-11 12:40:48
问题 I'm connecting to the Twitter Streaming API and am setting up the OAuth handshake. I need to request a token and send a callback_url as a params dictionary along with post request. I've hardcoded in the url for development (http://localhost:8000/oauth) but when I deploy this will change. I want to set up something that will find the host and port and set a reference it. Ideally, looking like "http://%s/oauth" % (domain_name) I've tried using both the os and socket modules, and code is below:

Docker Compose

由 蓝咒 提交于 2019-12-11 10:04:18
Compose负责实现对Docker容器集群的快速编排。定位是 定义和运行多个Docker容器的应用，前身是Fig。 Compose允许用户通过单一docker-compose.yml模板文件(YAML格式)来定义一组相关的应用容器为一个项目。通过子命令对项目中的一组容器进行生命周期管理。 Compose中两个重要概念： 服务（service）：一个应用的容器，实际上可以包含若干运行相同镜像的容器实例。 项目（project）：由一组关联的应用容器组成的一个完整业务单元，在docker-compose.yml文件中定义。 Compose项目由Python编写，实现上调用了Docker服务提供的API来对容器进行管理。因此，只要所操作的平台支持DockerAPI，就可以利用compose进行编排管理。 安装与卸载 Compose支持Linux、macOS、Windows10三大平台。 Compose可以通过Python的包管理工具pip进行安装，也可以直接下载编译好的二进制文件使用，甚至可以直接在Docker容器中运行。 Docker Desktop for Mac/Windows自带docker-compose二进制文件，安装Docker之后可以直接使用。 书上是建议直接下载二进制文件（版本号注意调整成最新）。 curl -L https://github.com/docker
