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).

Answer 1

无法配置DataSource：未指定’url’属性，也无法配置嵌入数据源

可能是.properties文件中datasource的配置出现错误，例如：地址值，数据库驱动，用户名，密码。
