通过 Yaml 配置 H2 数据库 - Spring 启动
Configuring H2 database via Yaml - Spring Boot
我有一个 spring 启动应用程序，我想用 Yaml 配置我的 H2 数据库。每当我 运行 this.
时它就会崩溃
我的 app.yml 文件：
spring:
database: h2
console: true
path: /h2
datasource:
platform: h2
url: jdbc:h2://localhost:8080/h2
username: sa
password: 1234
driverClassName: org.h2.Driver
pom.xml
<dependencies>
<!-- H2 Database -->
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
</dependency>
....
</dependencies>
我不会很好地使用yaml，我需要帮助，看看我的yaml是否可以修复以合并H2数据库。
我正在尝试这样做：https://dzone.com/articles/integrate-h2-database-in-your-spring-boot-applicat
但是 app.yml 而不是 app.properties。
提前致谢！
编辑： 这是我的崩溃，
