我正在使用 Spring MVC、Hibernate 和 SQLite，当我运行服务器时，一切正常，但数据库没有创建，也不异常(exception)。当我从 java 类启动 persistence.xml 时，它会创建数据库
public static void main(String[] args) throws Exception {
ApplicationContext context = new ClassPathXmlApplicationContext(
"/META-INF/persistence-config.xml");
String[] names = context.getBeanDefinitionNames();
System.out.println(context.getBeanDefinitionCount());
for (String name : names) {
System.out.println("name Bean == " + context.getBean(name).getClass());
}
}
这是persistence.xml

请您参考如下方法:
您是否尝试过在 JDBC URL 属性中放置绝对 URL(具有 W/R 权限)？
例如:
<property name="url" value="jdbc:sqlite:c:\\franchise.db" /> (in Windows)
检查数据库是否在正确的路径(C:/franchise.db)上创建。
