问题背景
在连接mysql的时候出现报错：

解决方案
1 从报错中可以看见找不到Datasource数据库的配置，经检查原来忘了在application.yml配置文件配置数据库信息了
spring:
datasource:
#url: jdbc:mysql://[ip]:[port]/[name]?useSSL=false&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&allowPublicKeyRetrieval=true&serverTimezone=Asia/Shanghai
url: jdbc:mysql://localhost:3306/mysqlTest?serverTimezone=UTC&characterEncoding=UTF-8
username: root
password: 123456
driver-class-name: com.mysql.cj.jdbc.Driver
sql:
init:
encoding: utf-8
心得
- 有时就是忘了一些配置信息导致报错
