航信电子发票开发（servlet请求方式）
在系统用户交费后，需要打印发票，可以选择普票或者机打票（票据信息在系统中自定义设置的），也可以打印电子发票，这里对接的是航信的电子发票，请求方式非web服务，而是使用servlet通过HTTP请求的方式获取报文。
整个开票流程如下：
本地组装发票明细信息到报文（内部报文加密）——》将组装好的发票信息发往税控服务器——》成功的话解析返回的信息——》发票打印
报文格式：
实际测试报文如下：

主要代码如下：
1. 页面选打印电子发票后，确定进入下面方法
public Result printElectronic(PrintInvoiceEntity entity) { // 电子发票不允许进行预览 if (entity.getIsPreview()) { return new Result(Status.ERROR, null, "电子发票不允许进行预览!"); } if (PrintCallingTypeEnum.HEATING.getCode().equals(entity.getPrintCallingType())) { //打印热费的电子发票 return this.printElectronicForHeating(entity); } else { return new Result(Status.ERROR, null, "未指定打印票据的调用方式!"); } }
附：相关实体类
public class PrintInvoiceEntity { /* ------------------- 非必填字段 ---------------------*/ private String volumeCode;//票据册号（当票据类型为电子发票时非必填） /* ------------------- 必填字段 ---------------------*/ private String companyCode;//开票公司编码 private String gmf_mc;//购买方名称 private String gmf_nsrsbh;//购买方纳税人识别号 private String gmf_dzdh;//购买方地址电话 private String gmf_yhzh;//购买方银行账户 private String bz;//备注 private String card_no; private String create_time; private String printCallingType;//打印调用方式 private Boolean isPreview;//是否预览模式 private Boolean isPreprint;//是否预开模式 private String invoiceType;//票据类型 List<PjItemEntity> pjItemEntities;//票据打印明细
2. 打印电子发票方法
private Result printElectronicForHeating(PrintInvoiceEntity entity) { // 正常采暖费交费时，获取上年结余 printInvoiceService.initSurplus(entity.getPjItemEntities()); // 根据交易明细组装发票明细信息 List<Invoice> invoices = printInvoiceService.splitInvoice( SessionUtil.getUser(), entity); // 调用航信税控进行打票 List<Map<String, String>> returnMsg = this.printForHeating(invoices, entity, null); if (returnMsg.isEmpty()) { return new Result(Status.ERROR, null, "电子发票开具失败！"); } return new Result(Status.OK, null, returnMsg); }
3. 组装发票明细信息
// 将交易明细拆分成发票 public List<Invoice> splitInvoice(User operator, PrintInvoiceEntity entity) { List<Invoice> invoices = new ArrayList<Invoice>(); // 1.初始化字典项数据 Map<String, String> chargeItemDict = initChargeItemDict();// 收费项目 // Map<String, Dict> unitPriceTypeDict = initUnitPriceTypeDict();// 单价类别 Map<String, Dict> areaTypeDict = initAreaTypeDict();// 面积类别 Map<String, XtwhTaxRate> taxRateDict = initTaxRateDict(); // 税率 Map<String, SfOtherCost> otherCostDict = initOtherCostDict(); // 第三方费用 List<PjItemEntity> pjItemEntities = entity.getPjItemEntities(); String customerIds = pjItemEntities.get(0).getSysattachment() .get(InvoiceInfoConstant.CUSTOMER_COLLECTION_ALIAS); String[] idArray = customerIds.split(","); String companyCode = this.getCompanyCode(entity, idArray[0]); String prjName = DeployConfigUtil.getJcDeployConfig().getProjectName(); JcCustomer jccustomer = this.getJccustomer(entity, idArray[0]); String userKindType =null; if (jccustomer !=null) { userKindType= jccustomer.getUserKindCode(); } // 4.获取公共的发票抬头模板 InvoiceSummary commonSummary = this.createInvoiceSummary(operator, companyCode); for (int i = 0; i < pjItemEntities.size(); i++) { // 浅复制发票抬头对象 InvoiceSummary summary = commonSummary.clone(); // 发票请求流水号 summary.setFpqqlsh(SerialNumberUtil.getNextNumber(2)); // 1.同步购买方信息 summary.setGmf_mc(entity.getGmf_mc());// 销售方-名称 summary.setGmf_nsrsbh(entity.getGmf_nsrsbh());// 销售方-纳税人识别号 summary.setGmf_dzdh(entity.getGmf_dzdh());// 销售方-地址电话 summary.setGmf_yhzh(entity.getGmf_yhzh());// 销售方-银行账户 summary.setCard_no (entity.getCard_no());// 销售方-银行账户 summary.setCreate_time (entity.getCreate_time());// 销售方-银行账户 if ("0".equals(prjName)) { summary.setBz(entity.getBz()); } else if("1".equals(prjName)){ if (jccustomer!=null && "user_type_2".equals(jccustomer.getUserTypeCode())) { // 二部制用户 summary.setBz(entity.getBz()+", 上年结余:"+pjItemEntities.get(i).getSurplus());// 备注 }else{ summary.setBz(entity.getBz()); } } Invoice invoice = this.splitInvoiceDetail( entity.getPrintCallingType(), summary, pjItemEntities.subList(i, i + 1), chargeItemDict, areaTypeDict, taxRateDict, otherCostDict, userKindType); invoices.add(invoice); } return invoices; }
将交易明细拆分成发票上的多个明细项
public Invoice splitInvoiceDetail(String printCallingType, InvoiceSummary summary, List<PjItemEntity> pjItemEntities, Map<String, String> chargeItemDict, Map<String, Dict> areaTypeDict, Map<String, XtwhTaxRate> taxRateDict, Map<String, SfOtherCost> otherCostDict, String userKindType) { List<InvoiceDetail> invoiceDetails = new ArrayList<InvoiceDetail>(); for (PjItemEntity pjItemEntity : pjItemEntities) { // 交易明细为热费 List<InvoiceDetail> list = this.createInvoiceDetailsByHeatingCost( printCallingType, pjItemEntity, chargeItemDict, areaTypeDict, taxRateDict , userKindType); invoiceDetails.addAll(list); } // 2.同步合计金额 BigDecimal hjje = BigDecimal.ZERO;// 合计金额 BigDecimal hjse = BigDecimal.ZERO;// 合金税额 for (InvoiceDetail invoiceDetail : invoiceDetails) { hjje = BigDecimalUtil.add(hjje, new BigDecimal(invoiceDetail.getXmje())); hjse = BigDecimalUtil.add(hjse, new BigDecimal(invoiceDetail.getSe())); } summary.setHjje(hjje.toString()); summary.setHjse(hjse.toString()); BigDecimal jshj = BigDecimalUtil.add(hjje, hjse);// 价税合计 summary.setJshj(jshj.toString()); // 3.组装发票 Invoice invoice = new Invoice(); invoice.setSummary(summary); invoice.setDetails(invoiceDetails); return invoice; }

4. 调用航信税控进行打票
public List<Map<String, String>> printForHeating(List<Invoice> invoices, PrintInvoiceEntity entity, PjInfo bluePjinfo) { List<Map<String, String>> returnMsg = new ArrayList<Map<String, String>>(); String prjName = DeployConfigUtil.getJcDeployConfig().getProjectName();// 0:项目A 1:项目B // 将组装好的发票信息发往税控服务器进行电子发票打印 String requestXml = null; // 请求报文 String returnXml = null; // 请求报文对应的返回报文 InvoiceReturnEntity invoiceReturnEntity = null; // 开票返回报文对应的实体 PjItemEntity pjItemEntity = null; // 票据打印原始数据 Invoice invoice = null; // 票据实体 PjInfo pjInfo = null; for (int i = 0; i < invoices.size(); i++) { invoice = invoices.get(i); pjItemEntity = entity.getPjItemEntities().get(i); JcCustomer jcCustomer = printInvoiceService.getJccustomer(entity,pjItemEntity.getCustomerId().toString()); String userKindType=null; if (jcCustomer != null) { userKindType = jcCustomer.getUserKindCode(); } // 将开具的电子发票信息保存到收费系统票据信息表中 pjInfo = ElnvoiceEntityUtil.createPjInfo( entity.getPrintCallingType(), entity.getIsPreprint(), invoice, bluePjinfo); pjInfoService.insert(pjInfo); //蓝票冲红 if(bluePjinfo != null){ invoice.getSummary().setPjInfoId(bluePjinfo.getId()); }else{ invoice.getSummary().setPjInfoId(pjInfo.getId()); } if ("0".equals(prjName)) { if (StringUtils.defaultString(invoice.getSummary().getYfp_dm()).length() > 0 && StringUtils.defaultString(invoice.getSummary().getYfp_hm()).length() > 0) { // 封装航信电子发票所需报文--红冲 requestXml = LFEInvoiceXmlUtil.createHCEInvoiceXml(invoice,userKindType); } else { // 封装航信电子发票所需报文 requestXml = LFEInvoiceXmlUtil.createEInvoiceXml(invoice, userKindType); } // 请求航信开票接口开具报文 returnXml = EInvoiceWsUtil.eInvoice(requestXml); // 解析返回报文 invoiceReturnEntity = LFElnvoiceEntityUtil.createInvoiceReturnEntity(returnXml); } else { if (StringUtils.defaultString(invoice.getSummary().getYfp_dm()).length() > 0 && StringUtils.defaultString(invoice.getSummary().getYfp_hm()).length() > 0) { // 封装航信电子发票所需报文--红冲 requestXml = EInvoiceXmlUtil.createHCEInvoiceXml(invoice); } else {// 封装航信电子发票所需报文 requestXml = EInvoiceXmlUtil.createEInvoiceXml(invoice); } // 请求航信开票接口开具报文 returnXml = EInvoiceWsUtil.eInvoice(requestXml); // 解析返回报文 invoiceReturnEntity = ElnvoiceEntityUtil.createInvoiceReturnEntity(returnXml); } if (!RETURN_CODE_SUCCESS .equals(invoiceReturnEntity.getReturnCode())) { continue; } // 将开具的电子发票信息保存到收费系统票据信息表中 pjInfo = ElnvoiceEntityUtil.updatePjInfo(pjInfo, invoiceReturnEntity); pjInfoService.updateById(pjInfo); // 记录开票明细 printInvoiceService.savepjItem(pjInfo.getId(), pjItemEntity); // 挂上电子发票与热用户的关联关系 printInvoiceService.savePjCustomerRelation(pjInfo.getId(),pjItemEntity); // 更新交易明细为已开票状态 printInvoiceService.updateInvoiceStatusForHeating(entity.getPrintCallingType(), pjItemEntity); // 推送到财务,此处正常开票、补打、冲红、集体交费逐户打印、全部打印都调用 printInvoiceService.insertRfglFinance(pjItemEntity, pjInfo, invoice); // 根据票据号请求电子发票下载地址 /* invoiceQueryEntity = ElnvoiceEntityUtil.createQueryInvoiceEntity(pjInfo); requestXml = EInvoiceXmlUtil.createQueryInvoiceXml(invoiceQueryEntity); returnXml = EInvoiceWsUtil.queryInvoice(requestXml); queryReturnEntity = ElnvoiceEntityUtil.createQueryReturnEntity(returnXml);*/ // 封装前台返回信息 Map<String, String> map = new HashMap<String, String>(); map.put("fpdm", invoiceReturnEntity.getFp_dm()); map.put("fphm", invoiceReturnEntity.getFp_hm()); map.put("downloadUrl", invoiceReturnEntity.getPdfUrl()); returnMsg.add(map); //下载pdf到本地 if(StringUtils.isNotEmpty(invoiceReturnEntity.getPdfUrl())){ try { downLoadByUrl(invoiceReturnEntity.getPdfUrl()); } catch (IOException e) { System.err.println("电子发票- PDF下载失败！"); e.printStackTrace(); } } } return returnMsg; }
相关实体：

5. 封装航信电子发票所需报文——》发送到航信接口开具报文——》解析包含开票信息的返回报文
5.1 生成电子发票开具报文
public static String createEInvoiceXml(Invoice invoice, String userKindType){ Document document = DocumentHelper.createDocument(); document.setXMLEncoding("utf-8"); // 默认utf-8 Element rootElement = getRoolElement(document, ""); String cdataXml =createEInvoiceCDATA(invoice, userKindType); //内部报文加密 Base64Encoder encoder = new Base64Encoder(); String comment = encoder.encode(cdataXml.getBytes()); Element dataElement = rootElement.element("Data"); dataElement.element("content").addText(comment); //xml文件"< >"禁止转义，保留<>样式的方法 String xml = StringEscapeUtils.unescapeXml(document.asXML()); return xml ; }
5.2 调用税控开具发票接口
public static String eInvoice(String wsXml){ String methodName = "eInvoiceCodes"; return EInvoiceWsUtil.invoke(methodName, wsXml); }
//调用远程服务接口的公共方法，获得包含开票信息的返回报文 public static String invoke(String methodName, String wsXml){ CloseableHttpClient httpclient = HttpClients.createDefault(); HttpPost httpPost = new HttpPost(webServiceUrl);// 创建httpPost httpPost.setHeader("Accept", "text/xml"); httpPost.setHeader("Content-Type", "text/xml"); String charSet = "UTF-8"; StringEntity entity = new StringEntity(wsXml, charSet); httpPost.setEntity(entity); CloseableHttpResponse response = null; try { response = httpclient.execute(httpPost); StatusLine status = response.getStatusLine(); int state = status.getStatusCode(); if (state == 200) { HttpEntity responseEntity = response.getEntity(); String jsonString = EntityUtils.toString(responseEntity); System.out.println("---response----"+jsonString); return jsonString; } else{ System.err.print("请求返回:"+state+"("+webServiceUrl+")"); } } catch(IOException e){ e.printStackTrace(); } finally { if (response != null) { try { response.close(); } catch (IOException e) { e.printStackTrace(); } } try { httpclient.close(); } catch (IOException e) { e.printStackTrace(); } } return null; }
5.3 解析返回报文，将信息保存进返回报文实体类
public static InvoiceReturnEntity createInvoiceReturnEntity(String returnXml){ InvoiceReturnEntity entity = new InvoiceReturnEntity(); try { Document document = DocumentHelper.parseText(returnXml); Element rootElement = document.getRootElement(); //business标签 Element element = null; Element headElement = rootElement.element("interface"); Element rtnElement = headElement.element("returnStateInfo"); String rtnCode = rtnElement.element("returnCode").getTextTrim(); Element dataElement = rootElement.element("Data"); //开票成功返回code if("0000".equals(rtnCode)){ // base64解码 String cdataXml = dataElement.element("content").getTextTrim(); String bodyXml = base64Decoder(cdataXml); Document bodyDoc = DocumentHelper.parseText(bodyXml); Element bodyElement = bodyDoc.getRootElement(); element = bodyElement.element("FPQQLSH"); entity.setFpqqlsh(element.getTextTrim()); element = bodyElement.element("FP_DM"); entity.setFp_dm(element.getTextTrim()); element = bodyElement.element("FP_HM"); entity.setFp_hm(element.getTextTrim()); element = bodyElement.element("KPRQ"); entity.setKprq(element.getTextTrim()); element = bodyElement.element("PDF_URL"); entity.setPdfUrl(element.getTextTrim()); } entity.setReturnCode(rtnCode); element = rtnElement.element("RETURNMESSAGE"); entity.setReturnMsg(element.getTextTrim()); } catch (DocumentException e) { System.err.println("电子发票-开具发票请求的返回报文解析失败！"); e.printStackTrace(); } return entity; }
6. 从网络Url中下载发票信息的pdf文件
public void downLoadByUrl(String urlStr) throws IOException{ URL url = new URL(urlStr); String[] str= urlStr.split("/"); String fileName= str[str.length-1]+".pdf"; String savePath = "C://upload"; HttpURLConnection conn = (HttpURLConnection)url.openConnection(); //设置超时间为3秒 conn.setConnectTimeout(2*1000); //防止屏蔽程序抓取而返回403错误 conn.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)"); //得到输入流 InputStream inputStream = conn.getInputStream(); //获取自己数组 byte[] getData = readInputStream(inputStream); //文件保存位置 File saveDir = new File(savePath); if(!saveDir.exists()){ saveDir.mkdir(); } File file = new File(saveDir+File.separator+fileName); FileOutputStream fos = new FileOutputStream(file); fos.write(getData); if(fos!=null){ fos.close(); } if(inputStream!=null){ inputStream.close(); } } // 从输入流中获取字节数组 public byte[] readInputStream(InputStream inputStream) throws IOException { byte[] buffer = new byte[1024]; int len = 0; ByteArrayOutputStream bos = new ByteArrayOutputStream(); while((len = inputStream.read(buffer)) != -1) { bos.write(buffer, 0, len); } bos.close(); return bos.toByteArray(); }
