java - 从位置 'spring.profiles.active' 导入的属性 'class path resource [application-dev.yml]' 无效

Question

我将 Spring 云应用程序更新到最新的 Spring boot 版本 2.5.0。
但是在启动过程中我得到了这个异常:

11:05:05.038 [main] ERROR org.springframework.boot.SpringApplication - Application run failed
org.springframework.boot.context.config.InvalidConfigDataPropertyException: Property 'spring.profiles.active' imported from location 'class path resource [application-dev.yml]' is invalid in a profile specific resource [origin: class path resource [application-dev.yml] from skyshop-mail-1.0.jar - 42:17]
        at org.springframework.boot.context.config.InvalidConfigDataPropertyException.lambda$throwOrWarn$1(InvalidConfigDataPropertyException.java:125)

application.yml

spring:
    application:
        name: mail-service
    profiles:
        active: dev

你知道我该如何解决这个问题吗？

Answer 1

Spring Boot 2.4 改进了 application.properties 和 application.yml 文件的处理方式。
详情请看这里:https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-Config-Data-Migration-Guide
长话短说:如果你有一个 application-local.yml 并且你在里面定义了

spring:
profiles:
    active: local 

然后只需在 yaml 文件中删除此条目。
