Spring Boot read file on heroku

Spring Boot will fail with "getResource()" method to read the file in as on heroku it probably inside of a JAR file, which means it is not a regular file, and must be read as an input stream:

                .getResource("FILENAME.txt");


As a solution the file has to be read with "getResourceAsStream()":


MyService.class.getClassLoader()
                .getResourceAsStream("FILENAME.txt");
