[Solved] Failed to configure a DataSource: ‘url‘ attribute is not specified and no embedded datasource

Springboot does not specify the “url” property, and cannot configure an embedded data source. Cause: Unable to determine the appropriate driver class

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

Solution:

This is a dependency issue, using druid’s data pool to configure the database parameters and not importing druid’s package in pom.xml.

<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid-spring-boot-starter</artifactId>
<version>1.1.23</version>
</dependency>
