在FtpClient中用ftp FTP命令建自己要用的东东。。
由于sun没有公开FtpClient的API所以我们將就使用Sun的未公开类别暫時應急一下，方法命名大多與Common net ftpClient 雷同，不足的只好用issueCommand自己丟FTP命令：import java.io.FileNotFoundException;import java.io.IOException;import java.net.Proxy;import sun.net.TelnetInputStream;import sun.net.TelnetOutputStream;import sun.net.ftp.FtpClient;public class SundFtpClient extends FtpClient { public static final int ASCII_FILE_TYPE =0; public static final int BINARY_FILE_TYPE=2; public SundFtpClient(String host) throws IOException { super(host); } public SundFtpClient(String host, int port) throws IOException { super(host, port); } public int issueCommand(java.lang.String cmd) throws IOException{ return super.issueCommand(cmd); } public void issueCommandCheck(java.lang.String cmd) throws IOException{ super.issueCommandCheck(cmd); } public boolean setFileType(int fileType)throws IOException{ if(fileType==ASCII_FILE_TYPE){ return issueCommand("TYPE A")==1; }else{ return issueCommand("TYPE B")==1; } } public void enterLocalPassiveMode(){ try{ issueCommand("PASV"); }catch(IOException e){} } public boolean isConnected(){ return this.serverIsOpen(); } public void connect(java.lang.String hostname)throws java.io.IOException{ this.disconnect(); this.openServer(hostname); } public void connect(java.lang.String hostname,int port)throws java.io.IOException{ this.disconnect(); this.openServer(hostname,port); } public void disconnect()throws java.io.IOException{ if(this.serverIsOpen()) this.closeServer(); } public boolean deleteFile(String pathname)throws java.io.IOException{ try{ return issueCommand("DELE "+pathname)==1; }catch(FileNotFoundException e){ return false; } } public boolean makeDirectory(String pathname)throws java.io.IOException{ try{ return issueCommand("MKD "+pathname)==1; }catch(FileNotFoundException e){ return false; } } public boolean removeDirectory(String pathname)throws java.io.IOException{ try{ return issueCommand("RMD "+pathname)==1; }catch(FileNotFoundException e){ return false; } } public boolean sendNoOp()throws java.io.IOException{ return issueCommand("NOOP")==1; } public String printWorkingDirectory()throws java.io.IOException{ return super.pwd(); } public boolean changeToParentDirectory()throws java.io.IOException{ return issueCommand("CDUP")==1; } public boolean changeWorkingDirectory(String pathname)throws java.io.IOException{ try{ return issueCommand("CWD "+pathname)==1; }catch(FileNotFoundException e){ return false; } } public void storeFile(String remote,java.io.InputStream local)throws java.io.IOException{ byte[] buf = new byte; int readed=0; TelnetOutputStream outs = this.put(remote); synchronized (local) { while((readed=local.read(buf,0,1024))>0) outs.write(buf,0,readed); outs.flush(); outs.close(); local.close(); } } public void retrieveFile(String remote,java.io.OutputStream local)throws java.io.IOException{ byte[] buf = new byte; int readed=0; TelnetInputStream ins = this.get(remote); synchronized (local) { while((readed=ins.read(buf,0,1024))>0) local.write(buf,0,readed); local.flush(); local.close(); ins.close(); } }}测试代码：import java.io.IOException;import sun.net.ftp.FtpLoginException;/*
