datasource:
druid:

上述是黑马程序员苍穹外卖的yml里的druid配置，我复制在另一个项目的时候报错
Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
Process finished with exit code 1
后来发现是因为我新的项目用的是springboot3，而这个老项目用的2，很多人都说降版本可以解决，当然也可以改成下面：将druid放在type里
datasource:
driver-class-name: ${datasource.driver-class-name}
url: jdbc:mysql://${datasource.host}:${datasource.port}/${datasource.database}?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=true
username: ${datasource.username}
password: ${datasource.password}
type: com.alibaba.druid.pool.DruidDataSource
