当我启动我的 Spring Boot 应用程序时，我的数据库没有启动答案

【问题标题】：When I start my spring boot application, my database is not initiating当我启动我的 Spring Boot 应用程序时，我的数据库没有启动

【问题描述】：

我有一个 spring-boot 测试应用程序，我在 application.yml 文件中提供了以下配置。当我使用 mvn test 启动服务器时，它不会启动数据库连接，这可能是什么问题？我是否缺少 pom.xml 中的任何依赖项？

spring.datasource.driverClassName = com.ibm.db2.jcc.DB2Driver
spring.datasource.url=jdbc:db2://<fullURL>
spring.datasource.username = <uname>
spring.datasource.password = <password>

以下是我与 spring-boot 相关的依赖项

<dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
      <version>5.1.4.RELEASE</version>
  </dependency>
  <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-jdbc</artifactId>
  </dependency>

这是我的启动日志，其中我没有看到数据库连接日志

【问题讨论】：

您尝试使用 spring boot 连接哪个数据库？
尝试连接db2，但后来也尝试连接oracle，但都没有成功。
你没有显示任何试图与数据库对话的地方。如果您使用的是典型的池设置，则您的池在需要之前不会创建连接。（另请注意，您不应指定 Spring 依赖项的版本；它们是受管理的，并且您可能会引入不兼容性。您会收到警告并应注意它们。）

标签： java spring spring-boot

【解决方案1】：

我注意到的几件事：

您提到了application.yml，但文件的格式是属性
您需要在依赖项中添加驱动程序，以便 Spring Boot 也可以使用。
如果您正在运行测试，并且在src/test/resources 中有一个applicatio.yml，它将覆盖src/main/resources 中的那个
