    To read a file from a resource, you can write the following method:

     private String readResource(String name) { ClassLoader classloader = Thread.currentThread().getContextClassLoader(); try ( InputStream inputStream = classloader.getResourceAsStream(name); BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream)) ) { return reader.lines().collect(Collectors.joining("\n")); } catch (Exception e) { return null; } }

    And after reading, replace $value via replace :

     readResource("file.xml").replace("$value", "{some_value}");
