java上传文件与文件夹到服务器

文件：

String basePath = ServletActionContext.getServletContext().getRealPath("share"); //服务器路径获取        File savefile = new File(new File(basePath), uploadFileName);        try {            FileUtils.copyFile(upload, savefile);        } catch (IOException e) {            e.printStackTrace();        }

文件夹：

public String mutiUpload(){        if (folder == null) {            path=path+"";            return "mutiUpload";        }        File mutiFile=new File(folder);//folder为上传的文件夹全路径        String parent=mutiFile.getParent();//你上传的文件夹的根路径        try {            uploadMuti(folder,parent);        } catch (IOException e) {            e.printStackTrace();        }        setSuccessNextUrl("window.location.href='contract/contractFtp!changeDir.action?path="                    + path + "'");        return SUCCESS;    }    public boolean uploadMuti(String folder,String originPath) throws IOException{        File mutiFile=new File(folder);            String basePath = ServletActionContext.getServletContext().getRealPath("share");             String folderName=(mutiFile.getPath().replace(originPath, "")).replace("\\", "/");//文件夹名称            String folderPath=basePath+"/"+folderName;            File file=new File(folderPath);            file.mkdir();            File fileList[] = mutiFile.listFiles();             for(File upfile : fileList){                if (upfile.isDirectory()) {// 文件夹中还有文件夹                     folder=upfile.getPath();                    uploadMuti(folder,originPath);                }else{                    String path=(upfile.getPath().replace(originPath, "")).replace("\\", "/");                    String str[]=path.split("/");                    String workpath="";                    for(int i=0;i<str.length-1;i++){                        workpath=workpath+"/"+str[i];                    }                    String filePath=basePath+workpath;                    File savefile = new File(new File(filePath), upfile.getName());                    try {                        FileUtils.copyFile(upfile, savefile);                    } catch (IOException e) {                        e.printStackTrace();                    }                }            }        return true;    }

自己使用过后发现这种做法只能在自己搭建服务器的情况下从本机上传到服务器，而无法从其他机器上传。
