简单的TCPIP服务器端demo程序

【核心代码】

public void run()
{
   String reccharBuf = new String(); byte[] receiveBuf = new byte[BUFSIZE];
   SimpleDateFormat df=new SimpleDateFormat("yyyy/MM/dd/HH:mm:ss"); while (true) { //System.out.println("等待客户端连接。。。。" df.format(new Date()));  Console.showInformation("等待客户连接...." df.format(new Date()));
      Socket clntSock=null;
      BufferedInputStream in=null;//声明BufferedInputStream局部变量  try {
           clntSock = server.accept();
         clntSock.setSoTimeout(15000);
         SocketAddress clientAddress = clntSock.getRemoteSocketAddress(); //System.out.println("Handling client at"   clientAddress "/" df.format(new Date()));  Console.showInformation("正在处理来自"   clientAddress "/" df.format(new Date()));
         in = new BufferedInputStream(clntSock.getInputStream(), 1024);//得到从客户端发送来的数据，放到in中  while ((in.read(receiveBuf)) != -1) {
            reccharBuf=bytesToHex(receiveBuf);
            getMsg(receiveBuf);
            Iterator it = receiveBuf.iterator();//迭代器  while (it.hasNext()) {//检查迭代器中是否还有数据  //System.out.println(it.next());  Console.showInformation(it.next().toString());//将得到的数据打印出来  } datalist.clear();//清空集合中的数据  } //Iterator it = datalist.iterator();//迭代器  //while (it.hasNext()) {//检查迭代器中是否还有数据  //System.out.println(it.next());  // Console.showInformation(it.next().toString());  //}  if (datalist.isEmpty())
            { //setInsertindicator(true);  Console.showInformation("未收到数据"); //System.out.println("未收到数据");  } else{ //setInsertindicator(true);  }
      } catch (IOException e) { //System.out.println("客户端数据读取异常");  Console.showInformation("客户端数据读取异常");
         setInsertindicator(false); datalist.clear(); safeClose(in); safeClose(clntSock);
         e.printStackTrace();
      }finally{ datalist.clear();
      }
   }
