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).
Process finished with exit code 0**

这是我引入的依赖：


错误原因：原因是加载了数据库依赖而没有写配置文件
解决方法：
1、在SpringBootApplication后加（exclude=DataSourceAutoConfiguration.class）
2、把下面的依赖
org.mybatis.spring.boot mybatis-spring-boot-starter 2.1.1
注释掉

再次运行，报错就没有了。
