Question

带有h2的简单Spring Boot应用程序，该应用程序具有1个通过data.sql填充的DB表。如果我切换到2.0.0，则可以与spring-boot-starter-parent 1.5.9.RELEASE一起工作100％.RELEASE data.sql在启动时不再运行。

在我的pom.xml中，

 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
     <!-- <version>2.0.0.RELEASE</version> -->  
    <version>1.5.9.RELEASE</version>

    <relativePath/> <!-- lookup parent from repository -->
</parent>

        <scope>runtime</scope>       
    </dependency>

，以及一个SQL文件，该文件带有插入数据库表中的 src / main / resources / data.sql

在application.properties文件中

spring.datasource.url=jdbc:h2:file:~/greeter;AUTO_SERVER=TRUE
spring.datasource.initialization-mode=always

spring.jpa.show-sql=true
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=create-drop

在查看日志时使用1.5.9.RELEASE进行启动：

2018-07-23 17:53:41.219  INFO 11404 --- [           main] org.hibernate.tool.hbm2ddl.SchemaExport  : HHH000227: Running hbm2ddl schema export

使用2.0.0.RELEASE

我的application.properties文件似乎什么都没捡到。没有删除/重新创建数据库，也没有将data.sql导入到数据库中。和日志如下；它似乎与Maven有关。问题所在的启动日志

除了pom.xml中的版本已更改外，其他所有内容...

在Spring 2.0.0.RELEASE中需要什么才能使其运行？

编辑1编辑1编辑1 它似乎以某种方式与Maven依赖关系有关？如果我将存储库包含在pom.xml中，例如下面的所有内容都可以，请删除它们，我有上述问题

Answer 1

从h2-console连接时，请确保使用 jdbc:h2:mem:testdb 作为JDBC URL。当我们拥有h2提供的默认网址（jdbc:h2:~/test）时，您将不会在数据库中看到脚本结果。

此外，要在控制台上查看调试，只需将debug=true放在 application.properties 文件中。

内存中

URL jdbc：h2：mem：test表示打开一个内存数据库名为“测试”。数据不持久，最后一次连接时丢失到数据库已关闭。多个线程可以访问相同的数据库，但数据仅在同一进程中可见
