如何配置弹簧引导以使用基于文件的 H2 数据库
2022-08-31 12:53:49
我已成功创建了一个使用内存中 H2 嵌入式数据库的 Spring Boot 应用程序。我现在想将其更改为将保留的基于文件的版本。
我尝试更改文件中的属性,它们看起来像这样:spring.datasource.*
application.properties
spring.datasource.url=jdbc:h2:file:~/test;DB_CLOSE_ON_EXIT=FALSE
spring.datasource.username=test
spring.datasource.password=test
spring.datasource.driverClassName=org.h2.Driver`
似乎Spring Boot只是忽略了这些设置,因为它只是按如下方式启动:
o.s.j.d.e.EmbeddedDatabaseFactory : Starting embedded database: url='jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=false', username='sa'
My 包含以下可能与本文相关的依赖项:pom.xml

<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.5.RELEASE</version>

我从文档和一些帖子中的理解是,配置应该只是工作,但对我来说没有运气。只是为了防止一些基本错误,我尝试并检查了以下内容:
- 我的应用程序属性位于类路径中:
- 我试图在注释中排除自动配置
@EnableAutoConfiguration
- 我试图注入一个带有注释组合的bean,并用.以编程方式设置属性。这会导致与类型相关的其他错误。
dataSource
@Primary
@ConfigurationProperties(prefix = "spring.datasource")
DataSourceBuilder
null
似乎我错过了一个关键概念或其他东西。任何人都可以帮忙。
更新1:从我的自动配置报告中提取:

更新2:添加了执行器并查看了端点。这里有趣的是,我的配置已被采用并且数据库存在,但是当应用程序运行时,它不会使用它 。/configprops
