在HSQLDB中创建架构的启动脚本

在HSQLDB中创建架构的启动脚本

hibernate

我正在尝试使用内存数据库来模拟Teradata数据库。在构建表之前，我需要创建一个架构，但是，这很适合我。

我正在使用Spring，并且与进行了大量数据库交互import.sql，但是，这在Hibernate创建所有表之后执行。我试图使用.scriptHSQLDB应该读取的文件，但是我认为当您使用内存数据库无法正常工作时。我将文件移动了一点，似乎什么也没打。

任何人都知道如何在启动时为内存中的HSQLDB数据库创建架构吗？

如果您以这种方式运行脚本…

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd">


<jdbc:embedded-database id="dataSource" type="H2" >
    <jdbc:script location="classpath:my.sql" />     
</jdbc:embedded-database>

…然后在Hibernate进行初始化工作之前执行它。

我再次测试了它，特别是对您来说。它在Hibernate创建表之前运行。请参阅以下日志（ 在前三行中运行脚本，在最后三行中运行Hibernate ）：
