idea中使用SpringBoot框架无法读取yml配置文件:报错

2020-06-07 22:19:47 132 1

开发平台:windows10,开发工具:IDEA2018.3.5,使用框架:SpringBoot
问题:无法读取yml文件中的配置,但是使用properties文件却可以.
问题出现的环境背景及自己尝试过的方法

正在学习yml配置文件,以前并没有使用过,但是代码是没有问题的,尝试过把项目打包给朋友,两个以上的人尝试过了,可以运行,但是在我的电脑上会出现无法读取的情况.
如果将配置文件修改成properties,程序就可以正常运行.
yml文件中的代码 :

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/qy94?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC
    username: root
    password: 19960523.

报错信息:

    试试把密码用""包起来或者看下是不是数据库权限问题######没用的,试过了######

    你这是验证失败,不是无法读取。

    ######但是我的账户密码都对######

    猜测是你本地数据库没有 装好,

    ######装好了呀,我是用properties配置文件就可以正常走######

    这个yml没关系的, 是你配置写错了

    ######

    你的数据库账号问题导致的

    ######
    spring: datasource: name: MySql
    ######搞定了,yml文件无法编译点. 密码中带有点,所以连接不上数据库
