本篇內容介紹了“怎么實現java快遞電子面單打印接口對接demo”的有關知識，在實際案例的操作過程中，不少人都會遇到這樣的困境，接下來就讓小編帶領大家學習一下如何處理這些情況吧！希望大家仔細閱讀，能夠學有所成！
直接調用快遞鳥API。
首先登陸快遞鳥官網進行會員注冊http://www.kdniao.com/reg，
然后登錄快遞鳥官網后臺認證自己的用戶信息，記住自己的用戶ID和API key，代碼里調用接口時會使用到。我這里主要做個物流跟蹤的功能，所以我需要調用的物流跟蹤API，所以我需要先訂閱這個API的服務。大家如果想調用別的接口就相應的去訂閱就可以了。
然后在官網找到這里 點擊下載相應語言的demo
在對應的快遞鳥后臺，可以進行如下的批量打印。
想把這個打印功能集成到自己內部系統，可以下載官方的demo
跑起來挺容易的，直接放入tomcat運行就可以了
不過demo需要tomcat8.5，需要修改的話找到項目的.settings文件夾下有一個
org.eclipse.wst.common.project.facet.core.xml 將tomcat8.5修改為對應的版本就可以了。
官方demo代碼

/**

*/
public final static String getIpAddress(HttpServletRequest request) throws IOException {
// 獲取請求主機IP地址,如果通過代理進來，則透過防火墻獲取真實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有一個ip參數，獲取這個ip快遞鳥提供的方法是如下
// 獲取請求主機IP地址,如果通過代理進來，則透過防火墻獲取真實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;
}注意這個方法是沒有問題的，但是你如果直接輸入快遞單號OrderCode進行打印，這個時候提交總是說數據驗證不通過，并不是簽名問題，而是ip問題。
因為上一個方法只要是在局域網下面，即使能訪問外網，也沒用，獲取到的ip永遠都是內網ip
有一種方式可以在本地驗證通過，那就是直接百度ip，只有會有自己的ip地址
OK，在后臺將ip寫死，就可以進行打印預覽操作了。
打印需要安裝lodop打印插件，安裝完成之后訪問 http://localhost:8000/CLodopfuncs.js 會有相應的控件js
需要對應的打印插件，必須要有設備(熱敏打印機)，要不我也不至于出差了。
之后根據打印機型號，進入對應的官網下載打印驅動。之后perfect，就可以進行打印了。
官方demo給的是servlet
我使用的是SpringMVC，將代碼貼出。
