java - 无法从位置 'classpath:/application.yml' 加载属性源
问题描述
我application.yml在环境之间使用变量进行参数化，这些变量由标签设置，pom.xml当我在 IntelliJ Idea 中运行 JUnit 测试时，应用程序在加载时抛出错误application.yml
Caused by: while scanning for the next token
found character '@' that cannot start any token. (Do not use @ for indentation)
in 'reader', line 4, column 15:
auth-url: @auth.url@
我尝试编辑 IDE 运行配置并将变量放在引号内，但没有成功。通过终端运行总是可以的，只有在 IntelliJ IDEA 中不行
application.yml
spring:
application:
name: Application
auth-url: @auth.url@
profiles:
active: @activatedProperties@
data:
mongo:
host: @app.datasource.host@
port: @app.datasource.port@
database: @app.datasource.database@
password: @app.datasource.password@
username: @app.datasource.user@
