您好,這是因為你的 application.yml 文件中關于數據庫的配置格式出錯導致的。注意:datasource之前要有空格,也就是說完整的配置應該是 spring.datasource.driver-class-name.以下為我的配置:
spring:
?profiles:
? ?active: dev
?datasource:
? ?driver-class-name: com.mysql.jdbc.Driver
? ?url: jdbc:mysql://127.0.0.1:3306/ddgirl
? ?username: root
? ?password: root
?jpa:
? ?hibernate:
? ? ?ddl-auto: update
? ?show-sql: true
希望對你有幫助。
