if you want to read a file, you can use this code (fileName: "/certs/xxx")

public String readFile(String fileName) throws IOException {
        InputStream inputStream = this.getClass().getResourceAsStream(fileName);
        StringBuilder resultStringBuilder = new StringBuilder();
        try (BufferedReader br = new BufferedReader(new InputStreamReader(inputStream))) {
            String line;
            while ((line = br.readLine()) != null) {
                resultStringBuilder.append(line).append("\n");
            }
        }
        return resultStringBuilder.toString();
    }
