When configuring multiple environment files for springboot, you need to configure multiple YML files. The configuration before version 2.4 is as follows:

spring: 
  profiles:
    active: dev

But if SpringBoot’s version 2.4 later, it’s a reward.

org.springframework.boot.context.config.InvalidConfigDataPropertyException: Property ‘spring.profiles.active[0]’ imported from location ‘class path resource [application-work.yml]’ is invalid in a profile specific resource [origin: class path resource [application-work.yml] - 9:7]

Solution:

General layout changes as follows:

spring:
  config:
    activate:
       on-profile:
          - dev

Of course, it can also be solved by returning the spring boot version to before 2.4
