This tutorial will show you three different ways to change Spring Boot server port from its default 8080 to any other port you like.

The following steps are agnostic to your current Spring Boot’s embedded server, it should not make any difference whether you are using Tomcat, Jetty or Undertow.

Change server port through

In your file, add the server.port property to change Spring Boot server port. The following configuration sets the port to 9000:


Change server port through maven startup

However, if you’d like to change it upon startup without modifying the source code, launch the application through maven passing the server.port as an argument. You should run the command below from the root directory of your project (the one containing the pom.xml file:

mvn spring-boot:run -Drun.arguments="--server.port=9000"

Change server port on jar startup

Additionally, if you already have your application packaged into a jar file, launch it passing the server.port parameter:

java -jar -Dserver.port=9000 springboot-helloworld-0.0.1-SNAPSHOT.jar

Hope it helps.
