解决spring-boot启动中碰到的问题：Cannot determine embedded database driver class for database type NONE(转)

问题 如下：

@SpringBootApplication(exclude = {

)

public class PointshopWebApplication {

    public static void main(String[] args) {

        SpringApplication.run(PointshopWebApplication.class, args);

    }

}

　　但是很 遗憾 ，没用。

于是 用maven下载 好springboot 的源码，然后断点调试 进去 ，看看 是什么情况，最后 发现了问题的所在：

因为我这是一个新 项目 ，还 没有 配置数据源 ，但是我又想在 没配置数据源的情况 下去 启动项目，该怎么办呢 ？网上找到的方法是无效的，于是我做了一个大胆的猜测：肯定是某个地方加载了这个bean,因为 这是 一个新项目，所以 我觉得 启动加载的可能性很大，而启动 加载 只有 POM文件 里面的依赖才 有可能办到。下面 是 我的dependency依赖：

　　一个个排查，最后查到org.mybatis.spring.boot这个依赖 ，注释掉即可,可以发现，调试的时候 beannames明显少了很多。

spring boot启动原理步骤分析

spring boot最重要的三个文件:1.启动类 2.pom.xml 3.application.yml配置文件 一.启动类->main方法 1.spring boot通过fat jar方式用jdk命令java -jar jarname.jar启动的. fat jar就是包含被引用jar包的jar,因为会包含很多jar包,所以称为fat,肥胖. 2.spring  boot通过static void main方法启动,main方法是java程序总是最先运行的地方,这个是由jvm虚拟机决定的.任
