To manage comments for a node, use the CommentsApi and the following methods:

For more information about this ReST API endpoint, see Manage Comments for a Folder or File.

For a description of the common parameters, such as include, see Common Parameters.

@Component
public class ManageCommentsCmd {
    static final Logger LOGGER = LoggerFactory.getLogger(ManageCommentsCmd.class);

    private Integer skipCount = 0;
    private Integer maxItems = 100;
    private List<String> fields = new ArrayList<>();

    // Fetch only the fields we are interested in
    public ManageCommentsCmd() {
        fields.add("content,createdAt");
    }

    @Autowired
    CommentsApi commentsApi;

    public void execute(String nodeId) throws IOException {
        Comment firstComment = createComment(nodeId, "First comment");
        Comment secondComment = createComment(nodeId, "Second comment");

        LOGGER.info("Listing comments: ");
        CommentPagingList comments = commentsApi.listComments(nodeId, skipCount, maxItems, fields).getBody().getList();
        for (CommentEntry commentEntry: comments.getEntries()) {
            LOGGER.info("    {}", commentEntry.getEntry());
        }
    }

    private Comment createComment(String nodeId, String text) {
        CommentBody commentBody = new CommentBody();
        commentBody.setContent(text);
        Comment comment = commentsApi.createComment(nodeId, commentBody, fields).getBody().getEntry();
        LOGGER.info("{}", comment);
        return comment;
    }
}

Note the use of the fields parameter to limit the number of fields returned with each call, which saves bandwidth.

Executing the code gives a log like follows:
