Read a file from resources folder with getResource() for static and non-static context

Read a file from resources folder with getResource() for static and non-static context:

File Location: 

src/main/resources
|--->mock-response/monga-response.json

Method implementation for non-static context:

   public String readResponseFromFile(String fileName) throws URISyntaxException, IOException {
        File inputFile = new File(this.getClass().getResource("/" + fileName).toURI());
        return FileUtils.readFileToString(inputFile);

   }

If you want to load a file from the resources folder from a static context you must use the class name.

Method Implementation for static context:

    public static String readResponseFromFile(String fileName) throws URISyntaxException, IOException {
        File inputFile = new File(MockingUtil.class.getClassLoader().getResource(fileName).getFile());
        return FileUtils.readFileToString(inputFile);

    }

Method Call:

dataFetcher.setHttpClient(MockingUtil.getMockHttpClient(MockingUtil.readResponseFromFile("mock-response/monga-response.json")));
