First you have to tell Spark where to search for the static files like this:
Spark.staticFiles.location("/public");
In Spark versions prior to 2.5, you should use:
Spark.staticFileLocation("/public");
Then your project should have a public
folder under the resources folder like this
/src/main/resources/public/style.css
For example I added a style.css
file there, so you should then access it like this:
http://localhost:4567/style.css
If you want to serve a non-classpath folder, then you should use
Spark.staticFiles.externalLocation("/path/to/dir");
In Spark versions prior to 2.5, you should use:
Spark.externalStaticFileLocation("/path/to/dir");
