H2数据库在内存中 - 通过Spring / Hibernate启动模式 [英] H2 database In memory - Init schema via Spring/Hibernate
问题描述
我有一个H2数据库的Spring / Hibernate应用程序,在配置H2以嵌入模式运行时(内存中),我遇到了一些问题:
1.我希望spring能够启动H2数据库,所以我创建了以下Spring bean:
I have a Spring/Hibernate application with H2 database and I have a few issues with configuring H2 to run in an embedded mode (in memory):
1. I want spring to start the H2 database so I created the following Spring beans:
<bean id="org.h2.tools.Server" class="org.h2.tools.Server"
factory-method="createTcpServer" init-method="start" destroy-method="stop">
<constructor-arg value="-tcp,-tcpAllowOthers,true,-tcpPort,8043" />
</bean>
<bean id="org.h2.tools.Server-WebServer" class="org.h2.tools.Server"
factory-method="createWebServer" init-method="start">
<constructor-arg value="-web,-webAllowOthers,true,-webPort,8082" />
</bean>
我是否需要在内存中使用tcp服务器?这是在内存中的正确配置吗?
Do I need to use the tcp server at all for in-memory use? Is this the correct configuration for in memory?
2.有了上述配置 - 如何在Hibernate启动之前创建并初始化数据库模式?
我知道HSQLDB有一个URL属性,它指出了创建脚本的名称。这里有类似的方法吗?
2.With the above configuration - How can I create and init the database schema before Hibernate is started? I know that HSQLDB has a URL property that states the name of the creation script. Is there a similar way here?
感谢您的帮助
Thanks for the help
推荐答案
Hibernate有一个名为 schemaUpdate
的属性。将它设置在你的 SessionFactory
上,这样数据库就可以在初始化时创建。
Hibernate has a property called schemaUpdate
. Set it on your SessionFactory
so that the database is created on initialization.
<property name="schemaUpdate" value="true" />
如果您使用的是JPA,那么有一个 generateDdl
要在 JpaVendorAdapter
If you are using JPA, then there is a generateDdl
property that is to be set on the JpaVendorAdapter
