Usage

From source file:org.forgerock.openig.migrate.Main.java

void execute(OutputStream stream) throws Exception {

    // Pre-parse the original files with JSON-Simple parser (which is more lenient than Jackson's one)
    File source = new File(sources.get(0));
    JSONParser parser = new JSONParser();
    JSONObject object = (JSONObject) parser.parse(new FileReader(source));

    // Then serialize again the structure (should clean up the JSON)
    StringWriter writer = new StringWriter();
    object.writeJSONString(writer);//from   w  w w . ja  va2 s . c  om

    // Load migration actions to apply in order
    List<Action> actions = loadActions();

    // Parse the cleaned-up content with Jackson this time
    JsonFactory factory = new JsonFactory();
    ObjectMapper mapper = new ObjectMapper();
    ObjectNode node = (ObjectNode) mapper.readTree(writer.toString());

    // Apply migration actions
    for (Action action : actions) {
        node = action.migrate(node);
    }

    // Serialize the migrated content on the given stream (with pretty printer)
    DefaultPrettyPrinter prettyPrinter = new DefaultPrettyPrinter();
    prettyPrinter.indentArraysWith(DefaultPrettyPrinter.Lf2SpacesIndenter.instance);
    mapper.writeTree(factory.createGenerator(stream).setPrettyPrinter(prettyPrinter), node);
