When you open a new springboot project:

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).

First, check whether the yml data source configuration file is correct, account password, etc…

I found that there is no resource file in the target file. A closer look shows that there is no icon in the resource file.

Solution:

Step 1: Select the corresponding item and right-click: Open Module Settings

Step 2: Click in sequence according to the corresponding steps, and finally don’t forget to Apply

If other startup errors fail, you can leave a comment!
