我尝试做java -jar jarname.jar，但出现错误。
但是，如果我在STS上启动项目，则不会收到以前的错误。
我不明白为什么它不起作用，为什么STS可以工作，而jar也不起作用。

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).
答案 0 :(得分：0)
您做了任何特定的配置或设置吗？
答案 1 :(得分：0)
似乎在STS中，您已经以某种方式配置了参数url。如果使用java -jar启动应用程序，则还必须提供参数。例如：java -jar myspringbootapp.jar --url=jdbc:blabla
