springboot项目启动报Access denied for user ''@'192.168.150.1' (using password: NO)错误

原因是根据idea的提示，直接按回车使用了data-url，data-username，data-password的标签 = =

原来的配置文件如下：

server:
  port: 9001
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    data-url: jdbc:mysql://192.168.150.130:3306/sr?characterEncoding=utf-8
    data-username: root
    data-password: 123456

改正后如下

server:
  port: 9001
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://192.168.150.130:3306/sr?characterEncoding=utf-8
    username: root
    password: 123456
