二、OfficePdfUtil 工具类

public class OfficePdfUtil {
    public static boolean getLicense(){
        boolean result = false;
        try {

            String license =
                    "n" +
                            "  n" +
                            "    n" +
                            "      Aspose.Total for Javan" +
                            "      Aspose.Words for Javan" +
                            "    n" +
                            "    Enterprisen" +
                            "    20991231n" +
                            "    20991231n" +
                            "    8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7n" +

                            "";
            InputStream is = new ByteArrayInputStream(license.getBytes("UTF-8"));
