Question

我有一个maven项目需要一个内存数据库来存储数据过滤后的数据集，因为它只是一个ETL项目，所以它不使用spring / spring boot框架，所以请使用hibernate来构建嵌入式H2。一切正常，我可以对H2进行CRUD，但是我不知道是否要使用远程spring boot项目连接到此H2 DB，我应该设置什么？

这是我在maven项目中的文件： pom.xml

        <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
            <version>1.4.200</version>
        </dependency>

        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-core</artifactId>
            <version>5.4.22.Final</version>
        </dependency>

在春季启动项目中

（我已经运行db2.datasource.url=jdbc:h2:mem:test，并且工作正常，所以我只粘贴属性代码）： application.properties

db2.datasource.driverClassName=org.h2.Driver
db2.datasource.url=jdbc:h2:tcp://10.250.31.42:9092/mem:test
spring.h2.console.enabled=true
spring.h2.console.path=/h2-console
db2.datasource.username=sa
db2.datasource.password=

有人可以帮助我解决这个问题吗？谢谢加濑
