虽然已经实现了FTP上传,但是目前却只能上传英文路径,该问题依旧等待解决的方案

一、所需软件:

FTP服务器:ServUSetup.exe 下载地址为:http://www.rhinosoft.com/__release/ServUSetup.exe

Java FTP 库edtFTPj/Free:下载地址为:http://www.enterprisedt.com/products/edtftpj/download/edtftpj.zip

二、edtFTPj/Free实现了以下功能

1、上传指定文件夹(包括子文件和文件夹) uploadFolder(String folderName, String ftpPath)

2、下载FTP上指定的文件夹 downloadFolder(String ftppath, String outdir, String ftpdir)

3、上传指定文件夹下的所有文件到FTP指定目录下 uploadAllFilesInFolder(String folderName, String ftpPath)

4、删除指定文件夹下的所有文件(包括子文件夹里面的文件,但由于不知怎么删除目录,所以暂没有做删除目录的功能) deleteAllFilesInFolder(String ftppath, String ftpdir)

5、删除指定文件 String deleteFile(String ftpPath)

6、判断FTP上目录是否存在 isDirExist(String dirname, String[] files)

7、上传单个文件 uploadFile(String clientFileName, String ftpPath)

8、下载单个文件 downloadFile(String remoteFileName,String localFileName)

9、删除指定文件夹下的所有文件(不包括子文件夹,只是删除指定文件夹下的文件)

三、实现过程

0、安装FTP服务器,配置域名、用户名、密码以及根目录

1、连接FTP服务器

/**************************************************************************

调用该构造函数的格式为:FtpService ftp=new FtpService("127.0.0.1","21","admin","admin");

打印效果如下则表示连接服务器成功

开始登录
登录成功
已转入根目录

    public FtpService(String pFtpServer, String pFtpPort, String pFtpUserName,String pFtpPassword) throws Exception   
    {   
        this.ftpServer = pFtpServer;   
          if (pFtpPort.trim().equals(""))   
           this.ftpPort = "21";   
          else 
           this.ftpPort = pFtpPort;   
          if (pFtpUserName.trim().equals(""))   
           this.ftpUserName = "Anonymous";   
          else 
           this.ftpUserName = pFtpUserName;   
          this.ftpPassword = pFtpPassword;   
          try {      
                    ftpClient = new FTPClient(); //ftpServer, Integer.parseInt(ftpPort)   
                    ftpClient.setRemoteHost(ftpServer);   
                    ftpClient.setRemotePort(Integer.parseInt(ftpPort));   
                    ftpClient.setControlEncoding("gbk"); //加上这一句后在 edtftpj 2.0.1 下就可以传中文文件名了   
                    System.out.println("开始登录");   
                    ftpClient.connect();   
                    ftpClient.login(ftpUserName, ftpPassword);   
                    System.out.println("登录成功");   
                    ftpClient.chdir("\\"); //在有的ftp服务器运行会出错,用ftpClient.chdir("/")又可以了   
                    System.out.println("已转入根目录");   
                    isLogin = true;   
          } catch (Exception e) {   
           throw new Exception(e.getMessage());   
          }   
   } 
/**

    public FtpService(String pFtpServer, String pFtpPort, String pFtpUserName,String pFtpPassword) throws Exception
    {
    this.ftpServer = pFtpServer;
       if (pFtpPort.trim().equals(""))
        this.ftpPort = "21";
       else
        this.ftpPort = pFtpPort;
       if (pFtpUserName.trim().equals(""))
        this.ftpUserName = "Anonymous";
       else
        this.ftpUserName = pFtpUserName;

                 isLogin = true;
       } catch (Exception e) {
        throw new Exception(e.getMessage());
       }
   }

2、实现上传文件函数:上传指定文件夹下的所有文件到FTP指定目录下
view plaincopy to clipboardprint?
/** 
     * 上传指定文件夹下的所有文件到FTP指定目录下 
     * @param folderName 本地要上传的文件夹全路径 
     * @param ftpPath FTP上对于根目录的路径 
     * @throws IOException 
    */       
    public void uploadAllFilesInFolder(String folderName, String ftpPath) throws   
            Exception {   
        if (isLogin) {   
            String strMsg = "";   
            try {   
                File file = new File(folderName);   
                if (file.isDirectory()) {   
                    ftpClient.chdir("\\");   
                    ftpClient.setType(FTPTransferType.BINARY);   
                    if (checkFolderIsExist(ftpPath)) {   
                        ftpClient.chdir(ftpPath);   
                    } else {   
                        createFolder(ftpPath);   
                    }   
                    File[] files = file.listFiles();   
                    for (int i = 0; i < files.length; i++) {   
                        if (files[i].isFile()) {   
                            try {   
                                ftpClient.put(files[i].getPath(),   
                                              files[i].getName());   
                            } catch (Exception ee) {   
                                strMsg += "upload file<<:" + files[i].getPath() +   
                                        ">> error!Message:" + ee.getMessage() +   
                                        "\r\n";   
                            }   
                        }   
                    }   
                } else {   
                    throw new Exception(folderName + " is not a folder'name!");   
                }   
            } catch (Exception e) {   
                throw new Exception(e.getMessage());   
            }   
        } else {   
            throw new Exception("you didnot login remote ftp server!");   
        }   
    } 
/**
     * 上传指定文件夹下的所有文件到FTP指定目录下
     * @param folderName 本地要上传的文件夹全路径
     * @param ftpPath FTP上对于根目录的路径
     * @throws IOException
    */    
    public void uploadAllFilesInFolder(String folderName, String ftpPath) throws
            Exception {
        if (isLogin) {
            String strMsg = "";
            try {
                File file = new File(folderName);
                if (file.isDirectory()) {
                    ftpClient.chdir("\\");
                    ftpClient.setType(FTPTransferType.BINARY);
                    if (checkFolderIsExist(ftpPath)) {
                        ftpClient.chdir(ftpPath);
                    } else {
                        createFolder(ftpPath);
                    }
                    File[] files = file.listFiles();
                    for (int i = 0; i < files.length; i++) {
                        if (files[i].isFile()) {
                            try {
                                ftpClient.put(files[i].getPath(),
                                              files[i].getName());
                            } catch (Exception ee) {
                                strMsg += "upload file<<:" + files[i].getPath() +
                                        ">> error!Message:" + ee.getMessage() +
                                        "\r\n";
                            }
                        }
                    }
                } else {
                    throw new Exception(folderName + " is not a folder'name!");
                }
            } catch (Exception e) {
                throw new Exception(e.getMessage());
            }
        } else {
            throw new Exception("you didnot login remote ftp server!");
        }
    }


3、实现上传单个文件函数

view plaincopy to clipboardprint?
/** 
     * 上传单个文件 uploadFile(String clientFileName, String ftpPath) 
     * @param clientFileName 本地要上传的文件的全路径 
     * @param ftpPath FTP上对于根目录的路径 
     * @throws IOException 
    */ 
    public void uploadFile(String clientFileName, String ftpPath) throws 
            Exception {   
        if (isLogin) {   
            try {   
                //获取文件名   
                String filename = "";   
                int index = clientFileName.lastIndexOf("\\");   
                filename = clientFileName.substring(index + 1);   
                ftpClient.chdir("\\");   
                ftpClient.setType(FTPTransferType.BINARY);   
                if (checkFolderIsExist(ftpPath)) {   
                    ftpClient.chdir(ftpPath);   
                } else {   
                    createFolder(ftpPath);   
                }   
                ftpClient.put(clientFileName, filename);   
            } catch (Exception ex) {   
                throw new Exception(ex.getMessage());   
            }   
        } else {   
            throw new Exception("you didnot login remote ftp server!");   
        }   
    } 
/**
     * 上传单个文件 uploadFile(String clientFileName, String ftpPath)
     * @param clientFileName 本地要上传的文件的全路径
     * @param ftpPath FTP上对于根目录的路径
     * @throws IOException
    */
    public void uploadFile(String clientFileName, String ftpPath) throws
            Exception {
        if (isLogin) {
            try {
                //获取文件名
                String filename = "";
                int index = clientFileName.lastIndexOf("\\");
                filename = clientFileName.substring(index + 1);
                ftpClient.chdir("\\");
                ftpClient.setType(FTPTransferType.BINARY);
                if (checkFolderIsExist(ftpPath)) {
                    ftpClient.chdir(ftpPath);
                } else {
                    createFolder(ftpPath);
                }
                ftpClient.put(clientFileName, filename);
            } catch (Exception ex) {
                throw new Exception(ex.getMessage());
            }
        } else {
            throw new Exception("you didnot login remote ftp server!");
        }
    }
