Change Java spark port number

Question

My java spark web application using the embedded jetty web server uses port number 4567. Unfortunately this port number is blocked on my computer and don't wish to unblock it. If looked at the spark documentation but it doesn't contain how to change the port number of the embedded Jetty server to 8080.

This might be a dupe. Have you checked this question: http://stackoverflow.com/questions/24644114/change-jetty-default-port — Daniel Wisehart, Aug 31 '16 at 23:34

You can set the port number in your java spark web application using the function port(). This has to be done before using routes and filters

official documentation link: http://sparkjava.com/documentation.html#port

Example

port(8080);
// Routes of your endpoint...
