Could not auto-size column. Make sure the column was tracked prior to auto-s......

注释ExportExcel.java中

sheet.autoSizeColumn(i);

加密方法，记录：

public static byte[] getByteDataSource(String title,List<?> list, String password, Class<?> pojoClass) throws IOException {
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        try {
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            new ExportExcel(title, pojoClass, 1).setDataList(list).write(baos).dispose();

            //创建excel解析对象
            POIFSFileSystem fs = new POIFSFileSystem();
            EncryptionInfo info = new EncryptionInfo(EncryptionMode.standard);
            Encryptor enc = info.getEncryptor();
            //设置密码
            enc.confirmPassword(password);
            //加密文件
            OPCPackage opc = OPCPackage.open(new ByteArrayInputStream(baos.toByteArray()));
            baos.close();

            OutputStream os = enc.getDataStream(fs);
            opc.save(os);
            opc.close();

            fs.writeFilesystem(out);    //把加密后的文件写回到流
            fs.close();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                out.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return out.toByteArray();
    }

其他：maven-shade-plugin可以解决依赖包多版本引用
