Description:

Reason: Failed to determine suitable jdbc url
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).

如果您使用的是springboot数据jpa，请在属性中使用“jdbcUrl”：
spring.datasource.jdbcUrl=jdbc:mysql://127.0.0.1:3306/database
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/database
如果您使用的是springboot+mybatis，请在属性中使用“url”：
spring.datasource.jdbcUrl=jdbc:mysql://127.0.0.1:3306/database
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/database
根据您的pom文件，我认为您正在使用H2（内存数据库）进行测试，并使用postgres进行真正的应用程序；由于您正在尝试运行应用程序，因此需要使用spring属性在属性文件中指定数据库的url，例如：spring.datasource.url=jdbc:postgresql://here_your_url:5432/here_your_db […]spring.datasource.username=here\u您的用户名[…]spring.datasource.password=here\u您的密码[…]我第一次玩这种东西时，请始终遵守正确的安全程序（PPE不是开玩笑的）。在新手见面之前，一切都很有趣。
