本篇内容介绍了“怎么实现java快递电子面单打印接口对接demo”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！
直接调用快递鸟API。
首先登陆快递鸟官网进行会员注册http://www.kdniao.com/reg，
然后登录快递鸟官网后台认证自己的用户信息，记住自己的用户ID和API key，代码里调用接口时会使用到。我这里主要做个物流跟踪的功能，所以我需要调用的物流跟踪API，所以我需要先订阅这个API的服务。大家如果想调用别的接口就相应的去订阅就可以了。
然后在官网找到这里 点击下载相应语言的demo
在对应的快递鸟后台，可以进行如下的批量打印。
想把这个打印功能集成到自己内部系统，可以下载官方的demo
跑起来挺容易的，直接放入tomcat运行就可以了
不过demo需要tomcat8.5，需要修改的话找到项目的.settings文件夹下有一个
org.eclipse.wst.common.project.facet.core.xml 将tomcat8.5修改为对应的版本就可以了。

/**

public final static String getIpAddress(HttpServletRequest request) throws IOException {
// 获取请求主机IP地址,如果通过代理进来，则透过防火墙获取真实IP地址
String ip = request.getHeader("X-Forwarded-For");
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("Proxy-Client-IP");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("WL-Proxy-Client-IP");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("HTTP_CLIENT_IP");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("HTTP_X_FORWARDED_FOR");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getRemoteAddr();
}
} else if (ip.length() > 15) {
String[] ips = ip.split(",");
for (int index = 0; index < ips.length; index++) {
String strIp = (String) ips[index];
if (!("unknown".equalsIgnoreCase(strIp))) {
ip = strIp;
break;
}
}
}
return ip;
}
}但是，需要注意的是，API有一个ip参数，获取这个ip快递鸟提供的方法是如下
// 获取请求主机IP地址,如果通过代理进来，则透过防火墙获取真实IP地址
public final static String getIpAddress(HttpServletRequest request) throws IOException {
String ip = request.getHeader("X-Forwarded-For");
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("Proxy-Client-IP");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("WL-Proxy-Client-IP");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("HTTP_CLIENT_IP");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("HTTP_X_FORWARDED_FOR");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getRemoteAddr();
}
} else if (ip.length() > 15) {
String[] ips = ip.split(",");
for (int index = 0; index < ips.length; index++) {
String strIp = (String) ips[index];
if (!("unknown".equalsIgnoreCase(strIp))) {
ip = strIp;
break;
}
}
}
return ip;
}注意这个方法是没有问题的，但是你如果直接输入快递单号OrderCode进行打印，这个时候提交总是说数据验证不通过，并不是签名问题，而是ip问题。
因为上一个方法只要是在局域网下面，即使能访问外网，也没用，获取到的ip永远都是内网ip
有一种方式可以在本地验证通过，那就是直接百度ip，只有会有自己的ip地址
OK，在后台将ip写死，就可以进行打印预览操作了。
打印需要安装lodop打印插件，安装完成之后访问 http://localhost:8000/CLodopfuncs.js 会有相应的控件js
需要对应的打印插件，必须要有设备(热敏打印机)，要不我也不至于出差了。
之后根据打印机型号，进入对应的官网下载打印驱动。之后perfect，就可以进行打印了。
官方demo给的是servlet
我使用的是SpringMVC，将代码贴出。
final String EBussinessID = "12677**";//kdniao.com EBusinessID
final String AppKey = "8e9dcb4b-f0a1-42f6-9d80-372a67f851**"; //kdniao.com AppKey
final Integer IsPreview = 1; //是否预览 0-不预览 1-预览
