问题分析：

在spring boot配置文件application.yml中我的配置是:

spring:

datasource:

db-name:

url:

username:

password:

...

spring boot org.springframework.boot.autoconfigure.jdbc.DataSourceProperties无法找到datasource下的定义的db-name数据库链接

解决方法：

方法一：

spring:
datasource:
name: product
url:

    jdbc:
    username: root
    password:
    driverClassName: com.mysql.cj.jdbc.Driver

取消db-name的配置

方法二：

自定义DataSourceConfig
