SpringBoot单元测试时报错 :: Driver claims to not accept

SpringBoot启动时报错:

错误代码 : : Driver claims to not accept
原因排查 : 连接数据库的url配置错误 :

1. 修改前 :

   spring:
   	datasource:
   		driver-class-name: 
   	url: mysql://localhost:3306/travel
   	username: root
   	password: root
   

2. 修改后：

   spring:
   	datasource:
   		driver-class-name: 
   	url: jdbc:mysql://localhost:3306/travel		# 少复制了 jdbc:
   	username: root
   	password: root
