java實(shí)現(xiàn)服務(wù)端代碼 java服務(wù)器代碼
用java代碼實(shí)現(xiàn)客戶(hù)端與服務(wù)端建立連接？
套接字 Socket
網(wǎng)站建設(shè)哪家好，找創(chuàng)新互聯(lián)！專(zhuān)注于網(wǎng)頁(yè)設(shè)計(jì)、網(wǎng)站建設(shè)、微信開(kāi)發(fā)、重慶小程序開(kāi)發(fā)、集團(tuán)企業(yè)網(wǎng)站建設(shè)等服務(wù)項(xiàng)目。為回饋新老客戶(hù)創(chuàng)新互聯(lián)還提供了黃州免費(fèi)建站歡迎大家使用！
import java.net.*;
Server:
ServerSocket server=new ServerSocket(port);//port是端口
Socket socket=server.accept();
//等待客戶(hù)機(jī)的連接請(qǐng)求，若連接，則創(chuàng)建一套接字，并將返回。
Client:
Socket socket=new Socket("host",port);//host主機(jī)名（本機(jī)：127.0.0.1）
用java多線(xiàn)程實(shí)現(xiàn)服務(wù)器與客戶(hù)端之間的文件傳輸?shù)拇a！??！急?。。?！
程序分Server和Client
服務(wù)器端打開(kāi)偵聽(tīng)的端口，一有客戶(hù)端連接就創(chuàng)建兩個(gè)新的線(xiàn)程來(lái)負(fù)責(zé)這個(gè)連接
一個(gè)負(fù)責(zé)客戶(hù)端發(fā)送的信息(ClientMsgCollectThread 類(lèi))，
另一個(gè)負(fù)責(zé)通過(guò)該Socket發(fā)送數(shù)據(jù)（ServerMsgSendThread ）

關(guān)于java，soap服務(wù)器端的代碼怎么寫(xiě)
soapenv:Header/
soapenv:Body
api:getEmp
shopIdstring/shopId
/api:getEmp
/soapenv:Body
/soapenv:Envelope
這個(gè)時(shí)SOAP協(xié)議的標(biāo)準(zhǔn)報(bào)文格式，客戶(hù)端只要發(fā)送這樣的報(bào)文給支持SOAP協(xié)議的webservice服務(wù)器即可成功調(diào)用web service服務(wù)
服務(wù)端：部署服務(wù)只需要自己定義服務(wù)的接口和實(shí)現(xiàn)類(lèi)，并用@webservice注解，通過(guò)endPoint類(lèi)直接發(fā)布即可
編寫(xiě)代碼，使用java ServerSocket創(chuàng)建服務(wù)器端ServerSocket的過(guò)程。
package?socket;
import?java.io.BufferedReader;
import?java.io.IOException;
import?java.io.InputStreamReader;
import?java.io.PrintWriter;
import?java.net.ServerSocket;
import?java.net.Socket;
public?class?SocketService?{
//搭建服務(wù)器端
public?static?void?main(String[]?args)?throws?IOException{
SocketService?socketService?=?new?SocketService();
//1、a)創(chuàng)建一個(gè)服務(wù)器端Socket，即SocketService?
socketService.oneServer();
}
public??void?oneServer(){
try{
ServerSocket?server=null;
try{
server=new?ServerSocket(5209);
//b)指定綁定的端口，并監(jiān)聽(tīng)此端口。
System.out.println("服務(wù)器啟動(dòng)成功");
//創(chuàng)建一個(gè)ServerSocket在端口5209監(jiān)聽(tīng)客戶(hù)請(qǐng)求
}catch(Exception?e)?{
System.out.println("沒(méi)有啟動(dòng)監(jiān)聽(tīng)："+e);
//出錯(cuò)，打印出錯(cuò)信息
}
Socket?socket=null;
try{
socket=server.accept();
//2、調(diào)用accept()方法開(kāi)始監(jiān)聽(tīng)，等待客戶(hù)端的連接?
//使用accept()阻塞等待客戶(hù)請(qǐng)求，有客戶(hù)
//請(qǐng)求到來(lái)則產(chǎn)生一個(gè)Socket對(duì)象，并繼續(xù)執(zhí)行
}catch(Exception?e)?{
System.out.println("Error."+e);
//出錯(cuò)，打印出錯(cuò)信息
}
//3、獲取輸入流，并讀取客戶(hù)端信息?
String?line;
BufferedReader?in=new?BufferedReader(new?InputStreamReader(socket.getInputStream()));
//由Socket對(duì)象得到輸入流，并構(gòu)造相應(yīng)的BufferedReader對(duì)象
PrintWriter?writer=new?PrintWriter(socket.getOutputStream());
//由Socket對(duì)象得到輸出流，并構(gòu)造PrintWriter對(duì)象
BufferedReader?br=new?BufferedReader(new?InputStreamReader(System.in));
//由系統(tǒng)標(biāo)準(zhǔn)輸入設(shè)備構(gòu)造BufferedReader對(duì)象
System.out.println("Client:"+in.readLine());
//在標(biāo)準(zhǔn)輸出上打印從客戶(hù)端讀入的字符串
line=br.readLine();
//從標(biāo)準(zhǔn)輸入讀入一字符串
//4、獲取輸出流，響應(yīng)客戶(hù)端的請(qǐng)求?
while(!line.equals("end")){
//如果該字符串為?"bye"，則停止循環(huán)
writer.println(line);
//向客戶(hù)端輸出該字符串
writer.flush();
//刷新輸出流，使Client馬上收到該字符串
System.out.println("Server:"+line);
//在系統(tǒng)標(biāo)準(zhǔn)輸出上打印讀入的字符串
System.out.println("Client:"+in.readLine());
//從Client讀入一字符串，并打印到標(biāo)準(zhǔn)輸出上
line=br.readLine();
//從系統(tǒng)標(biāo)準(zhǔn)輸入讀入一字符串
}?//繼續(xù)循環(huán)
//5、關(guān)閉資源?
writer.close();?//關(guān)閉Socket輸出流
in.close();?//關(guān)閉Socket輸入流
socket.close();?//關(guān)閉Socket
server.close();?//關(guān)閉ServerSocket
}catch(Exception?e)?{//出錯(cuò)，打印出錯(cuò)信息
System.out.println("Error."+e);
}
