I had the same problem and as @Gipple Lake explained, with Spring boot you need to load file as inputStream. So bellow I'll add my code as example, where I want to read import.xml file

public void init() {
    Resource resource = new ClassPathResource("imports/imports.xml");
    try {
        InputStream dbAsStream = resource.getInputStream();
        try {
            document = readXml(dbAsStream);
            } catch (SAXException e) {
                trace.error(e.getMessage(), e);
                e.printStackTrace();
            } catch (ParserConfigurationException e) {
                trace.error(e.getMessage(), e);
                e.printStackTrace();
            }
    } catch (IOException e) {
        trace.error(e.getMessage(), e);
        e.printStackTrace();
    }
    initListeImports();
    initNewImports();
}

public static Document readXml(InputStream is) throws SAXException, IOException,
      ParserConfigurationException {
      DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

      dbf.setValidating(false);
      dbf.setIgnoringComments(false);
      dbf.setIgnoringElementContentWhitespace(true);
      dbf.setNamespaceAware(true);
      DocumentBuilder db = null;
      db = dbf.newDocumentBuilder();

      return db.parse(is);
  }

I added "imports.xml" bellow src/main/ressources/imports
