客户这几天搞了个考勤展示外挂系统。
在公司的进门口搞了几块电子大屏幕。
显示每个员工的相片、到岗外出勤快、请假相关信息。
号称数据库仓储驾驶舱展现。老板喜欢~
销售也喜欢。
每到春天，客户就带着他们潜在的客户来参观考察。
展示各种电子显示屏。看起来确实高大上。
所有PA30的人事数据都同步过去了，就剩下头像相片信息没过去。
JAVA小哥哥想了很久，总算实现了~这里分享一下实现思路和解决方案。
SAP系统中，相片的存储格式为流文件，需要使用函数下载。
JAVA实现代码方案：
package com.ibm.ibmwriteback.util;
import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.util.Iterator;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.StringRequestEntity;
import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;
import sun.misc.BASE64Decoder;
public class SAPPhotoSync {
public static void getSAPEmployeePhoto(){
try{
HttpClient httpClient = new HttpClient();
System.out.println(“start visiting webservice!”);
PostMethod postMethod = new PostMethod(“http://10.1.0.217/cordys/com.eibus.web.soap.Gateway.wcp?organization=o=ibm,cn=cordys,cn=defaultInst1,o=ibm”);
String soapRequestData =
“<soapenv:Envelope xmlns:soapenv=\”http://schemas.xmlsoap.org/soap/envelope/\” xmlns:sap=\”http://schemas.cordys.com/tbpm/sapbpc\”>”+
“<soapenv:Header/>” +
“<soapenv:Body>” +
“<sap:ZHR_GET_PHOTO>” +
“<sap:PERNR>00000001</sap:PERNR>”+
“</sap:ZHR_GET_PHOTO>” +
“</soapenv:Body>” +
“</soapenv:Envelope>”;
StringRequestEntity requestEntity = new StringRequestEntity(soapRequestData,”text/xml”,”UTF-8″);
postMethod.setRequestEntity(requestEntity);
int statusCode = httpClient.executeMethod(postMethod);
if(statusCode == 200) {
System.out.println(“visiting webservice success!”);
InputStream result = postMethod.getResponseBodyAsStream();
SAXReader sb = new SAXReader();
Document doc = sb.read(result, “UTF-8”);
Element root = doc.getRootElement();
Iterator<Element> it = root.element(“Body”).element(“ZHR_GET_PHOTOResponse”).element(“T_BINARCHIVOBJECT”).elementIterator(“item”);
String str = “”;
while(it.hasNext()){
Element node = it.next();
str+=node.elementText(“LINE”);
}
BASE64Decoder decoder = new BASE64Decoder();
byte[] strByte = decoder.decodeBuffer(str);
String exportFile = “C:/empPhoto.jpg”;
FileOutputStream out = new FileOutputStream(new File(exportFile));
out.write(strByte);
out.close();
}else{
System.out.println(“error:”+postMethod.getResponseBodyAsString());
}
System.out.println(“visiting webservice end!”);
}catch(Exception e){
e.printStackTrace();
}
}
public static void main(String[] args){
getSAPEmployeePhoto();
}
}

运行完毕，即可下载SAP PA30的头像相片信息到SAP本地系统或者在外围系统显示出来。
如果想要进一步优化，可以先加入检测代码函数：HR_IMAGE_EXISTS
您学废了么？
