Spring Boot: Change Port for Web Application

Question

I am currently trying to create a web application with Spring Boot. I need to host my application to localhost:8081. How do I change the port?

Answer 1

Actually you want to change server.port and you can change it in many different ways as described http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-external-config

Examples:

• in your application.properties (in or outside the jar)

• command line

  java -Dserver.port=$PORT -jar target/demo-0.0.1-SNAPSHOT.jar

and much more
