關於springboot連接數據庫是報錯

連接mysql錯誤java.sql.SQLException: Access denied for user ''@'localhost' (using password: YES)

首先url加入?characterEncoding=utf8

datasource:
  driver-class-name: org.gjt.mm.mysql.Driver
  url: jdbc:mysql://localhost:3306/dbgirl
  user: root
  password: root

*可以通過的配置
spring:
  profiles:
    active: dev
  datasource:
    url: jdbc:mysql://localhost:3306/demoidea?characterEncoding=utf8
    username: root
    password: root
  jpa:
    hibernate:
      ddl-auto: create-drop
    show-sql: true


歡迎大神指點
