打印机打印小票代码(附工具类,接口讲解和源码)

废话不多说,直接上源码

1.工具类 PrintDeviceUtil

package com.ncxp.easy.util;import com.alibaba.fastjson.JSONObject;
import org.springframework.beans.factory.annotation.Value;import java.io.IOException;
import java.util.HashMap;
import java.util.Map;/*** 设备打印工具类*/
public class PrintDeviceUtil {/*** 打印类* @param url   通讯地址* @param deviceNo 设备编号* @param key  秘钥* @param content 打印内容* @param times 打印次数* @throws IOException*/public static JSONObject print(String url, String deviceNo, String key, String content, String times) throws IOException {Map<String, String> params= new HashMap<String, String>(16);params.put("deviceNo", deviceNo);params.put("key", key);params.put("printContent", content);params.put("times", times);String result = HttpClientTool.doPost(url + "/addOrder", params);JSONObject jsonObject = JSONObject.parseObject(result);return jsonObject;}/*** 查看打印状态* @param url* @param deviceNo* @param key* @param orderindex* @return* @throws IOException*/public static JSONObject printStatus(String url, String deviceNo, String key, String orderindex) throws IOException {Map<String, String> params= new HashMap<String, String>(16);params.put("deviceNo", deviceNo);params.put("key", key);params.put("orderindex", orderindex);String result = HttpClientTool.doPost(url + "/queryOrder", params);JSONObject jsonObject = JSONObject.parseObject(result);return jsonObject;}/*** 查看设备，在线状态* @param url* @param deviceNo* @param key* @return*/
//    public static JSONObject checkoutDeviceOnlinkStatus(String url, String deviceNo, String key) throws IOException {
//        Map<String, String> params= new HashMap<String, String>(16);
//        params.put("deviceNo", deviceNo);
//        params.put("key", key);
//        String result = HttpClientTool.doPost(url, params);
//        JSONObject jsonObject = JSONObject.parseObject(result);
//        return jsonObject;
//    }}

2.核心代码

参考打印设备接口: http://open.printcenter.cn:8080/index.jsp

try {
JSONObject jsonObject = PrintDeviceUtil.print(url, shopDevices.getDeviceNo(),
shopDevices.getMkey(), content, shopDevices.getTimes() + “”);
String responseCode = jsonObject.getString(“responseCode”);
if (“0”.equals(responseCode)) {
//获取打印设备的订单索引
String orderindex = jsonObject.getString(“orderindex”);
JSONObject jsonObject1 = PrintDeviceUtil.printStatus(url, shopDevices.getDeviceNo(),
shopDevices.getMkey(), orderindex);
String responseCode1 = jsonObject1.getString(“responseCode”);
if (“0”.equals(responseCode1)) {

               if(orListChange != null){//System.out.println("-----------------------"+orListChange.size()+"------------------------------------");if( returnCount == orListChange.size() ){///int count=0;for(OrderInfo orderInfo2:orListChange){if(orderInfo2.getShopPrint() == 0 ){count += orderGoodsService.updateByInfoId(orderInfo2.getOrderId(), orderInfo2.getGoodsId());}else{clearAllCont(totalPrice,totalPrice2,totalPriceTotal,orListChange);logger.error("商家端打印失败：订单中商品部分已经打印！" );}}if(count == orListChange.size()){/*System.out.println("====打印完之后的小票打印状态====" + orderGoodsService.getById(orderInfo.getId()).getShopPrint());System.out.println("====控制台输出订单打印内容===="+content);*/clearAllCont(totalPrice,totalPrice2,totalPriceTotal,orListChange);logger.info(content);logger.info("商家端打印成功");}else{if(k==shopDevicesList.size()){clearAllCont(totalPrice,totalPrice2,totalPriceTotal,orListChange);}logger.error("商家端打印失败：订单中商品未全部成功修改打印状态！" );}}else{if(k==shopDevicesList.size()){clearAllCont(totalPrice,totalPrice2,totalPriceTotal,orListChange);}logger.error("商家端打印失败：订单中商品未全部录入待打印状态！" );}}else{if(k==shopDevicesList.size()){clearAllCont(totalPrice,totalPrice2,totalPriceTotal,orListChange);}logger.error("商家端打印失败：无符合订单！" );}} else {if(k==shopDevicesList.size()){clearAllCont(totalPrice,totalPrice2,totalPriceTotal,orListChange);}logger.error("商家端打印失败：" + jsonObject1);}} else {if(k==shopDevicesList.size()){clearAllCont(totalPrice,totalPrice2,totalPriceTotal,orListChange);}logger.error("商家端打印失败：" + jsonObject);}} catch (IOException e) {if(k==shopDevicesList.size()){clearAllCont(totalPrice,totalPrice2,totalPriceTotal,orListChange);}logger.error("商家端打印失败:" + e.getMessage());}
