spring boot 创建项目引用mybatis后，直接运行会提示：

Cannot determine embedded database driver class for database type NONE

因为springboot启动时会自动注入数据源

使用@SpringBootApplication注解排除注入即可

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
public class Application {
    public static void main(String[] args){
        SpringApplication.run(Application.class, args);
    }
}
