Spring 中使用 HSQLDB

在spring的配置文件spring.xml中添加xmlns:jdbc， 申明hsqldb数据源创建hsqldb数据库，使用jdbc:initialize-database指明初始化数据库的sql脚本。

hsqldb2之后提供了对不同数据库语法的支持，例如使用可以通过sql.syntax_ora=true使hsqldb支持Oracle语法。

需要：hsqldb-1.8.0.10.jar

hsqldb的connection URL 按照下面表格中的规范定义

Driver and Protocol	Host and Port Example	Database Example
jdbc:hsqldb:mem:	not available	accounts

例子：spring.xml
