dataoutput.close();

                            fs.close();

                            dataSocket.close();

                            cmdinput.readLine();//服务器文件读入结束

                        } catch (IOException e) {

                            // TODO Auto-generated catch block

                            e.printStackTrace();

                            return 0;

                        }

                      }

                 }

                 break;

4   服务器端实现

4.1 receive.XML

cmdport为命令接收端口，datport为数据接收端口，根据客户端上传的localemachineident和localeupident找到第一个元素directoryreceive，读其中的参数:

<root>

 <serverip>11.68.17.167</serverip>

 <cmdport>10013</cmdport>

 <datport>10014</datport>

 <!-- 接收目录 -->

 <directoryreceive>

   <!-- 客户机在服务器配置中的源主机编号 -->

   <localemachineident>1</localemachineident>

   <!-- 客户机在服务器中的源目录编号,源主机编号加源目录编号唯一确定一个上传线程 -->

   <localeupident>1</localeupident>

   <!-- 接收策略 -->

   <receivetrategy trategy="weekcycle"/>

   <!-- 路径名不能为"\",必须为"/"或"\\(windows)" -->

   <receiverootdirectory>f:/test1</receiverootdirectory>

 </directoryreceive>

4.2 TransfileServer.Java

服务器端ServerSocket监听，当与客户端建立一个Socket连接时，创建处理线程:

       ReceiveFileDir receivefiledir=new ReceiveFileDir(cmdSocket,document,datss);

          receivefiledir.start();         

4.3 ReceiveFileDir

读入客户机上传的localemachineident和localeupident，根据上传目录或文件及接收目录封装方式(WeekCycle)分别调用ReceiveDir.Java、ReceiveFile.Java。

4.4 ReceiveDir和ReceiveFile

     接收客户端上传的数据，并保存到服务器指定目录:

            else if(cmdpara.equals("file"))

            {

                File file=new File(root+"/"+param);

                file.delete();

                System.out.println(root+"/"+param);

                RandomAccessFile fout;

                try {
