springboot 启动报错：Cannot determine embedded database driver class for database type NONE

springboot 启动时报：

Description:
Cannot determine embedded database driver class for database type NONE
Action:
If you want an embedded database please put a supported one on the classpath

原因是没有连接数据源的问题。

解决办法：
1.在@SpringBootApplication中排除其注入
@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})

2.如果是maven项目在pom.xml中注释掉springboot mybatis 依赖就可以了
