问题描述

开发平台:MacOS,开发工具:IDEA,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.

相关代码

#yml配置文件

server:

port: 9001

spring:

application:

name: tensquare-base # 微服务名称，在单个微服务中名称是没用的！在服务调用时使用的

datasource:

url: jdbc:mysql://127.0.0.1:3306/tensquare_base?useUnicode=true&characterEncoding=UTF8

driver-class-name: com.mysql.jdbc.Driver

username: root

password: 007397

jpa:

show-sql: true # 打印sql语句

generate-ddl: true # 自动建表(如果表存在，则不建表)

database: mysql

#properties配置文件

疑惑

1.首先我并未在任何地方设置172.17.0.1这一ip,这是SpringBoot默认的数据库地址吗?

2.为什么相同的程序,却获取不了配置文件?
