Apache Derby嵌入式模式部署 [英] Apache Derby Embedded Mode Deployment

问题描述

我有一个Java应用程序，它有一个嵌入式的Derby数据库（没有休眠）。该应用程序正在使用以下属性：

  datasource.driverClassName = org.apache.derby.jdbc.EmbeddedDriver 
 datasource .url = jdbc：derby：C：/ derby / mydb; 
 datasource.username = 1234 
 datasource.password = 1234 
  

一切正在工作罚款不错现在我需要打包所有的东西，并将它交给客户端安装在GlassFish服务器上，现在我不希望客户端安装Derby，我不希望他们知道应用程序正在使用数据库。

问题是：Derby应该在JAR中？ dataource.url应该是什么？

提前感谢

解决方案

您可以在Web应用程序中找到数据库数据文件。例如在WEB-INF / data /（当然，在WEB-INF / lib /中的Derby驱动程序文件）。

数据库在您提供给您的客户端的WAR文件中预配置（使用相对路径JDBC url）。他不必手动安装Derby DB。

注意：当您提供应用程序的更新时，您必须小心（不要擦除） DB）。

I have a Java app that has an embedded Derby database (no hibernate though). The app is using the following properties:

datasource.driverClassName = org.apache.derby.jdbc.EmbeddedDriver
datasource.url = jdbc:derby:C:/derby/mydb;
datasource.username = 1234
datasource.password = 1234

Everything is working fine and great. Now I need to package everything and give it to a client to install on their GlassFish server now I don't want the client to install Derby and I don't want them to know that the application is using a database.

The questions are: where should Derby be in the JAR? and What should the "datasource.url" be?

Thanks in advance.

解决方案

You can locate the database data files inside your web-app. For example in "WEB-INF/data/" (and the Derby driver file in "WEB-INF/lib/" of course).

So, you can embbed the database pre-configured (with a "relative-path" JDBC url) in the WAR file you give to your client. He won't have to install manually a Derby DB.

Note : you'll have to be careful when you'll provide an update of the application (to not erase the DB).
