Java中socket的代码模板

以你之姓@ 2022-05-20 01:55 164阅读 0赞

java的的socket的代码编写与C 语言的不太一样，C 语言的代码简练有深度，java的写起来复杂，但是不是那么难懂，因此在这里记录一下模板，防止以后忘记，总共四个文件，分别是ServiceServer.java（用于创建socket服务器），ServiceTask.java（服务器所提供的业务），DataProcess.java（服务器业务数据处理），ServiceCliect.java（socket客户端以及相关业务处理），代码如下

1.ServiceServer.java

package bigdata.socket;
    
    import java.io.IOException;
    import java.net.InetAddress;
    import java.net.InetSocketAddress;
    import java.net.ServerSocket;
    import java.net.Socket;
    
    import org.apache.log4j.net.SocketServer;
    
    public class ServiceServer {
    	
    	
    	public static void main(String[] args) throws IOException {
    		
    		
    		//创建一个serversocket ，然后绑定ip地址和端口号
    		ServerSocket server = new ServerSocket();
    		server.bind(new InetSocketAddress("lanc01", 8899));		
    		//等待接受客户端的连接，阻塞程序
    		while(true){	
    			
    			Socket accept = server.accept();//
    			new Thread(new ServiceTask(accept)).start();
    		}
    	}
    }

2.ServiceTask.java

package bigdata.socket;
    
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.InputStreamReader;
    import java.io.OutputStream;
    import java.io.PrintWriter;
    import java.net.Socket;
    
    public class ServiceTask implements Runnable{
    	
    	Socket socket;	
    	InputStream inputStream = null;
    	OutputStream outputStream = null;
    	
    	public ServiceTask(Socket accept) {
    		this.socket=accept;
    	}	
    	//客户端业务数据通信处理
    	@Override
    	public void run() {
    		
    		try {
    			//从socket连接中获取到与client之间的网络通信输入流
    			inputStream = socket.getInputStream();
    			outputStream = socket.getOutputStream();//输出流
    			BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
    			//从网络通信输入流中读取客户端发送过来的数据
    			//注意：socketinputstream的读书句的方法都是阻塞的
    			String readLine = bufferedReader.readLine();
    			//获取数据后业务处理
    			DataProcess dataProcess = new DataProcess();
    			String result = dataProcess.getdata(readLine);
    			
    			//将处理完的数据写到socket的输出流中，然后发送给客户端
    			//带回车的println，如果没有回车，就会一直读或者写，然后阻塞
    			PrintWriter printWriter = new PrintWriter(outputStream);
    			printWriter.println(result);
    			printWriter.flush();			
    		} catch (IOException e) {
    			e.printStackTrace();
    		}finally{
    			try {
    				inputStream.close();
    				outputStream.close();
    				socket.close();
    			} catch (IOException e) {
    				// TODO Auto-generated catch block
    				e.printStackTrace();
    			}			
    		}
    	}
    
    }

3.DataProcess.java

package bigdata.socket;
    
    public class DataProcess {
    	public String getdata(String param) {
    		
    
    		return "linux +++" + param;
    		
    	}
    
    }

4.ServiceCliect.java

package bigdata.socket;
    
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.InputStreamReader;
    import java.io.OutputStream;
    import java.io.PrintWriter;
    import java.net.ServerSocket;
    import java.net.Socket;
    
    public class ServiceCliect {
    	public static void main(String[] args) throws IOException {
    		
    		//建立socket向服务器发送连接请求
    		Socket socket = new Socket("lanc01",8899 );
    		InputStream inputStream = socket.getInputStream();
    		OutputStream outputStream = socket.getOutputStream();
    		//客户端向socket发送数据
    		PrintWriter printWriter = new PrintWriter(outputStream);
    		printWriter.println("==hello==");
    		printWriter.flush();
    		//读取数据
    		BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
    		String readLine = bufferedReader.readLine();
    		System.out.println(readLine);
    		
    		inputStream.close();
    		outputStream.close();
    		socket.close();
    		
    	}
    
    }
