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

 

原因：新创建的项目没有配置数据源  所以在项目启动的时候回去查找项目的数据源，但是发现找不到所以报错。

           如果配置了数据源之后  就算是没有排除自动配置数据源。

 

解决办法：

 

 

 

在启动类注解上

　　@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)

然后启动成功！

如果还不成功，

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@ComponentScan(basePackages = {"com.example.testtwo.dao"})
