【Spring Boot】（6）、Profile

Profile is Spring's support for providing different configuration functions for different environments, which can quickly switch environments by activating and specifying parameters.

When the main configuration file is written, the file name can be application-{profile}.properties

• application.properties: Default global configuration file

• application-dev.properties: development environment

• application-prod.properties: Production environment

• application-test.properties: test environment

2, yml supports multi-document block mode

  port: 8080
spring:
  profiles:

spring:
  profiles: dev


---
server:
  port: 8085
spring:
  profiles: prod

server:
  port: 8086
