springboot启动报错

报错信息如下：

***************************
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).

解决方法：在启动类上，排除此类的autoconfig。

@SpringBootApplication(exclude{DataSourceAutoConfiguration.class})

 

启动以后就可以正常运行
