我正在尝试在 Spring Boot 上运行一个项目。我配置了数据库连接，但出现了一个我无法理解的错误:

最佳答案
根据提供的堆栈跟踪，您的应用配置文件中存在错误。
它与这个 bean 有关:jpaConfiguration
由名为以下的注入(inject)依赖项失败引起:
值“${dataSource.driverClassName}”中的'dataSource.driverClassName'
问题在于...在您的应用程序属性中，变量的名称与 jpa 配置不匹配。应该是这样的:
@Value("${spring.datasource.driver-class-name}")
private String driver;
@Value("${spring.datasource.url}")
private String url;
@Value("${spring.datasource.username}")
private String username;
@Value("${spring.datasource.password}")
private String password;
修复该问题后，您会遇到同样的问题
@Value("${jpa.database-platform}")
private String databasePlatform;
@Value("${hibernate.ddl-auto}")
private String ddlAuto;
只要将这些名称匹配起来，我认为它应该可以工作!
