How to configure port for a Spring Boot application

How do I configure the TCP/IP port listened on by a Spring Boot application, so it does not use the default port of 8080.

Solution

  • As said in docs either set server.port as system property using command line option to jvm -Dserver.port=8090 or add application.properties in /src/main/resources/ with

    server.port=8090

    For a random port use:

    server.port=0

    Similarly add application.yml in /src/main/resources/ with:

    server:
  port: 8090
