Spring Boot - 应用程序无法运行。我认为这与我的数据源设置有关，但现在我认为这是一个依赖问题

Question

这是我遇到的错误：

也许和我的 Spring 版本有关？这是我第一次真正使用它，所以我没有太多的背景知识。

spring.datasource.url=jdbc:oracle:thin:@socratesdb_high?TNS_ADMIN=C:/Oracle/Wallet_SocratesDB
spring.datasource.username=ENS
spring.datasource.password=@wwnfK2&x#VpnPY7
spring.jpa.hibernate.ddl-auto=update

我一直在尝试将此处的内容更改/添加到我的 application.properties 文件中，但似乎没有帮助。

Answer 1

是的，这是一个依赖性问题。

您的 pom.xml 中需要 oracle 驱动程序依赖项

不仅仅是 Oracle，您使用的任何数据源，您都必须在 pom.xml 中添加其驱动程序依赖项

<dependency>
 <groupId>com.oracle.database.jdbc</groupId>
 <artifactId>ojdbc11</artifactId>
 <scope>runtime</scope>
