How to configure port for a Spring Boot application?

Hii team,

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.

Hello @kartik,

You can set port in java code:

HashMap<String, Object> props = new HashMap<>();
props.put("server.port", 9999);

new SpringApplicationBuilder()
    .sources(SampleController.class)                
    .properties(props)
    .run(args);

Or in application.yml:

server:
    port: 9999

Or in application.properties:

server.port=9999

Or as a command line parameter:

-Dserver.port=9999

Hope this works!!
