SpringBoot as much context switching

Method 1: Separate multiple profiles

# /src/main/resources/application.yaml
server:
	port: 8080
spring:
	profiles:
		active: dev

# /src/main/resources/application-dev.yaml
server:
	port: 8081

# /src/main/resources/application-test.yaml
server:
	port: 8082

Second way: written in the same configuration file

# /src/main/resources/application.yaml
server:
	port: 8080
spring:
	profiles:
		active: dev

---
server:
	port: 8081
spring:
	profiles: dev

---
server:
	port: 8082
spring:
	profiles: test
