本文實例講述了Java Socket實現(xiàn)傳輸壓縮對象的方法。分享給大家供大家參考，具體如下：
創(chuàng)新互聯(lián)專注于企業(yè)成都全網(wǎng)營銷推廣、網(wǎng)站重做改版、周口網(wǎng)站定制設(shè)計、自適應(yīng)品牌網(wǎng)站建設(shè)、H5響應(yīng)式網(wǎng)站、商城建設(shè)、集團(tuán)公司官網(wǎng)建設(shè)、成都外貿(mào)網(wǎng)站建設(shè)、高端網(wǎng)站制作、響應(yīng)式網(wǎng)頁設(shè)計等建站業(yè)務(wù)，價格優(yōu)惠性價比高，為周口等各大城市提供網(wǎng)站開發(fā)制作服務(wù)。
前面文章《Java Socket實現(xiàn)的傳輸對象功能示例》說到了用Java Socket來傳輸對象，但是在有些情況下比如網(wǎng)絡(luò)環(huán)境不好或者對象比較大的情況下需要把數(shù)據(jù)對象進(jìn)行壓縮然后在傳輸，此時就需要壓縮這些對象流，此時就可以GZIPInputStream和GZIPOutputStream來處理一下socket的InputStream和OutputStream。
仍然需要一個實現(xiàn)了java.io.Serializable接口的簡單Java對象
package com.googlecode.garbagecan.test.socket.sample4;
public class User implements java.io.Serializable {
private static final long serialVersionUID = 1L;
private String name;
private String password;
public User() {
}
public User(String name, String password) {
this.name = name;
this.password = password;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
在Server端使用，socket的InputStream首先被包裝成GZIPInputStream，然后又被包裝成ObjectInputStream，而socket的OutputStream首先被包裝成GZIPOutputStream，然后又被包裝成ObjectOutputStream，如下：
package com.googlecode.garbagecan.test.socket.sample4;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;
public class MyServer {
private final static Logger logger = Logger.getLogger(MyServer.class.getName());
public static void main(String[] args) throws IOException {
ServerSocket server = new ServerSocket(10000);
while (true) {
Socket socket = server.accept();
socket.setSoTimeout(10 * 1000);
invoke(socket);
}
}
private static void invoke(final Socket socket) throws IOException {
new Thread(new Runnable() {
public void run() {
GZIPInputStream gzipis = null;
ObjectInputStream ois = null;
GZIPOutputStream gzipos = null;
ObjectOutputStream oos = null;
try {
gzipis = new GZIPInputStream(socket.getInputStream());
ois = new ObjectInputStream(gzipis);
gzipos = new GZIPOutputStream(socket.getOutputStream());
oos = new ObjectOutputStream(gzipos);
Object obj = ois.readObject();
User user = (User)obj;
System.out.println("user: " + user.getName() + "/" + user.getPassword());
user.setName(user.getName() + "_new");
user.setPassword(user.getPassword() + "_new");
oos.writeObject(user);
oos.flush();
gzipos.finish();
} catch (IOException ex) {
logger.log(Level.SEVERE, null, ex);
} catch(ClassNotFoundException ex) {
logger.log(Level.SEVERE, null, ex);
} finally {
try {
ois.close();
} catch(Exception ex) {}
try {
oos.close();
} catch(Exception ex) {}
try {
socket.close();
} catch(Exception ex) {}
}
}
}).start();
}
}
Client也和Server端類似，同樣要不socket的XXXStream包裝成GZIPXXXStream，然后再包裝成ObjectXXXStream，如下：
package com.googlecode.garbagecan.test.socket.sample4;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketAddress;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;
public class MyClient {
private final static Logger logger = Logger.getLogger(MyClient.class.getName());
public static void main(String[] args) throws Exception {
for (int i = 0; i < 10; i++) {
Socket socket = null;
GZIPOutputStream gzipos = null;
ObjectOutputStream oos = null;
GZIPInputStream gzipis = null;
ObjectInputStream ois = null;
try {
socket = new Socket();
SocketAddress socketAddress = new InetSocketAddress("localhost", 10000);
socket.connect(socketAddress, 10 * 1000);
socket.setSoTimeout(10 * 1000);
gzipos = new GZIPOutputStream(socket.getOutputStream());
oos = new ObjectOutputStream(gzipos);
User user = new User("user_" + i, "password_" + i);
oos.writeObject(user);
oos.flush();
gzipos.finish();
gzipis = new GZIPInputStream(socket.getInputStream());
ois = new ObjectInputStream(gzipis);
Object obj = ois.readObject();
if (obj != null) {
user = (User)obj;
System.out.println("user: " + user.getName() + "/" + user.getPassword());
}
} catch(IOException ex) {
logger.log(Level.SEVERE, null, ex);
} finally {
try {
ois.close();
} catch(Exception ex) {}
try {
oos.close();
} catch(Exception ex) {}
try {
socket.close();
} catch(Exception ex) {}
}
}
}
}
最后測試上面的代碼，首先運行Server類，然后運行Client類，就可以分別在Server端和Client端控制臺看到接收到的User對象實例了。
