Spring Boot项目报错：Failed to configure a DataSource: ‘url‘ attribute is not specified and no embedded

一、错误描述

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2020-08-09 14:24:35.419 ERROR 2916 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   : 

***************************
APPLICATION FAILED TO START
***************************

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).

二、解决方法

在网上翻看了一些博客，找到了问题的缘由，翻译过来就是无法配置Datasource和url属性未指定

这些解决方案都尝试之后，发现都没有用，最终的解决办法是在启动类的头部加入以下内容

@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})

加入之后重新运行就没有报错了
