项目中遇到要和ESKO软件进行数据对接,采用热文件夹形式,走xml数据交互.记录下点滴.前提:文件目录局域网共享出来. 

上传xml:

//实现过程:先把一串XML数据源,写入本地文件,再通过SMB协议上传到指定服务器.可有办法直接把XML数据源写入远程?        String xml = "
    ";        String fileName="A.xml";		//本地服务的目录		String localFile = "\\\\192.168.0.100\\upload\\TEMPXML\\"+fileName;		//远程服务目录		String eskofilePath = YssetHelper.getESKOFilePath(session,"UP");		//先把xml写入本地目录		BufferedWriter bw = null;		try {			File dir = new File(localFile);			if (!dir.exists())				dir.createNewFile();			OutputStreamWriter writerStream = new OutputStreamWriter(new FileOutputStream(localFile),"UTF-8");			bw = new BufferedWriter(writerStream);			bw.write(xml);			bw.flush();		} catch (Exception e) {			throw e;		} finally {			if (bw != null) {				bw.close();			}		}		//本地文件传送至esko远程目录 smb://Administrator:yy@192.168.0.189/upload/XML        //若服务器账户密码有关键字@,则不能直接这么拼接.		try {			SMBUtil smb = SMBUtil.getInstance("smb:"+eskofilePath);			smb.init();	        File f = new File(localFile);	        smb.uploadFile(f);//上传文件 		} catch (Exception e) {			throw new Exception(e.getMessage());		}

下载xml数据:(这里就没必要写入文件了)

/**根据文件名到esko目录下找到xml文件,并转化为bean对象*/	public WorkOrder readXML(String fileName)throws Exception{		String eskofilePath = YssetHelper.getESKOFilePath(session,"DOWN");		SMBUtil smb = SMBUtil.getInstance("smb:"+eskofilePath+fileName);		smb.init();		String xmlStr = smb.downloadFile();		WorkOrder work = (WorkOrder)XmlUtil.xml2Java(xmlStr,WorkOrder.class);		return work;	}

下面贴上SMBUtil,想了解 xml2Java 和java2xml.可以关注我的其它文章.
