下文讲述一次 SpringBoot启动报错 Failed to determine a suitable driver class

今天配置文件中的本地数据库调整为云服务器的数据库地址时，重新启动出现以下错误，
  Description:

Failed to configure a DataSource: 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).

那么该如何处理此异常，下文将笔者的处理步骤分享如下:

步骤2

检查配置文件是否正确
配置文件名字是不是application-xxx.yml
application.yml是否激活指向XXX.yml

步骤2

application.properties中的数据库相关配置是否有误 驱动也要检查

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://【ip】:【端口】/【数据库名】?allowMultiQueries=true&serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=UTF-8&useSSL=false
spring.datasource.username=***
spring.datasource.password=***

步骤3

pom.xml文件中是否有依赖冲突
如引入了两个mysql驱动
