How to fix Spring Boot DataSource: 'url' attribute is not specified - spring-boot

Question

When I clone my project from git hub with another laptop. the console told me that below
Description:
Failed to configure a DataSource: 'url' attribute is not specified and 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).
The situation is very strange because the configuration with my original laptop can be work.
I already had configurated the relational properties in application.yaml like below
#datasource
spring:
datasource:
username: root
password: 123456
url: jdbc:mysql://localhost:3306/project?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
driver-class-name: com.mysql.cj.jdbc.Driver
mail:
host: smtp.gmail.com
port: 587
username: xxxx#gmail.com
password: 12345678
protocol: smtp
tls: true
properties.mail.smtp:
auth: true
starttls.enable: true
ssl.trust: smtp.gmail.com
#thymeleaf
thymeleaf: cache=false
#mybatis
mybatis.type-aliases-package: com.jason.pojo
mybatis:
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
and check relational dependencies.

changing:

to:
driverClassName: com.mysql.cj.jdbc.Driver

It seem that your application not scan your properties. So try adding this to you pom.xml and unchanged if you change the driverClassName property I have asked to changed.
