填坑：Access denied for user ‘‘@‘localhost‘ (using password: NO)

Spring啟動項目時出現此問題：

問題竟然在于IDEA的自動填充!!!

----------------正确--------------
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/db01?useUnicode=true&characterEncoding=utf-8
    username: root
    password: 123456

---------------錯誤-------------------
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/db01?useUnicode=true&characterEncoding=utf-8
    username: root
    data-password: 123456   #自動填充的是 data-password  然後就報錯using password: NO
