Java Socke Programmatic reading information blocking solution

1. The socket networking tool class will cause data blocking on the Read server

public class Connecttoserver {private static Boolean d=true;private static InputStream minputstream;private static Output Stream moutputstream;public Connecttoserver () {//TODO auto-generated Constructor stub}/** * Establish TCP connection * @param IP Server IP * @ param Port Port */public static Socket Conn (String Ip,int port) {try {socketsocket=new socket (inetaddress.getbyname (IP), por T), if (D) {log.i ("Socket", (socket==null) + "");} return socket;} catch (Exception e) {//Todo:handle Exception}return null;} /** * Send data msg to server * @param socket * @param msg to send data */public static void Sendreq (Socket socket,byte[] msg) {try {MOUTP Utstream=socket.getoutputstream (); Moutputstream.write (msg); Moutputstream.flush ();} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();}} /** * Data returned from the server * @param socket * @return */public static byte[] Recdata (socket socket) {int count = 0;try {minputstream=s Ocket.getinputstream (); byte[] Indatas = null;while (count = = 0) {count = Minputstream.available ();} Indatas =New Byte[count];minputstream.read (Indatas); return indatas;} catch (IOException E1) {//TODO auto-generated catch Blocke1.printstacktrace ();} return null;} /** * Close Connection freeing resource * @param socket */public static void Closeconn (socket socket) {if (moutputstream!=null) {try {MOUTPUTSTREAM.C Lose (); moutputstream=null;} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();}} if (minputstream!=null) {try {minputstream.close (); minputstream=null;} catch (IOException e) {//TODO auto-generated Catch Blocke.printstacktrace ();}} if (socket!=null) {try {socket.close (); socket=null;} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();}}}

2, when reading the server data, if the data is not read after a period of time, then close the connection to release resources. (This tool class takes 5 seconds as an example)

public class Connecttoserver {private static Boolean d=true;private static InputStream minputstream;private static Output Stream moutputstream;public Connecttoserver () {//TODO auto-generated Constructor stub}/** * Establish TCP connection * @param IP Server IP * @ param Port Port */public static Socket Conn (String Ip,int port) {try {socketsocket=new socket (inetaddress.getbyname (IP), por t); return socket;} catch (Exception e) {log.i ("exception Information", e.tostring ());} return null;} /** * Send data msg to server * @param socket * @param msg to send data */public static void Sendreq (Socket socket,byte[] msg) {try {MOUTP Utstream=socket.getoutputstream (); Moutputstream.write (msg); Moutputstream.flush ();} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();}} /** * Data returned from the server * @param socket * @return */public static byte[] Recdata (socket socket) {int count = 0;try {minputstream=s Ocket.getinputstream (); byte[] Indatas = null;while (count = = 0) {count = Minputstream.available (); try {// No response after 5 seconds (thread.sleep); if (Minputstream.avAilable () ==0) {//Close Connection Release resource closeconn (socket); catch (Exception e) {//Todo:handle exception}if (D) {log.i ("read service-side data", minputstream.available () + "");}} if (count==0) {return null;} Else{indatas = new Byte[count];minputstream.read (indatas); return indatas;}} catch (IOException E1) {//TODO auto-generated catch Blocke1.printstacktrace ();} return null;} /** * Close Connection freeing resource * @param socket */public static void Closeconn (socket socket) {if (moutputstream!=null) {try {MOUTPUTSTREAM.C Lose (); moutputstream=null;} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();}} if (minputstream!=null) {try {minputstream.close (); minputstream=null;} catch (IOException e) {//TODO auto-generated Catch Blocke.printstacktrace ();}} if (socket!=null) {try {socket.close (); socket=null;} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();}}}
