Connection reset 连接被重置的解决方法

流是java的核心部分,,昨天在做android服务器连接服务器的时候出了问题,就将代码放到java中执行,结果还是一样连接被重置

 

被重置的代码如下;

 

客户端代码;

package 通信软件服务器;

import java.io.BufferedWriter;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.Socket;
//客户端

public class SocketDemo {
	//private static String text="您好";

	public static void main(String[] args) {
		 //Connection reset 连接被重置
		try{
		//创建套接字的连接对象
		Socket socket = new Socket("127.0.0.1",9090);
		OutputStream os = socket.getOutputStream();
		OutputStreamWriter osw = new OutputStreamWriter(os);
		BufferedWriter bdw = new BufferedWriter(osw);
		//
		String text="您好";
		bdw.write(text, 0, text.length());
		bdw.flush();
	
		}catch(Exception e){
			e.printStackTrace();
		}
	}
}

 

服务器代码;

package 通信软件服务器;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class Demo {

	public static void main(String[] args) {
		try {
			ServerSocket server = new ServerSocket(9090);
			System.out.println("等待客户端连接");
			Socket socket = server.accept();
			System.out.println(socket.getRemoteSocketAddress() + "连接上服务器");
		   
			InputStream is = socket.getInputStream();
			InputStreamReader isr = new InputStreamReader(is);
			BufferedReader bis = new BufferedReader(isr);

			String line = bis.readLine();
			System.out.println("line:" + line);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

}

 

客户端连接服务器会出现以下结果;

等待客户端连接
/127.0.0.1:53373连接上服务器
java.net.SocketException: Connection reset
	at java.net.SocketInputStream.read(Unknown Source)
	at java.net.SocketInputStream.read(Unknown Source)
	at sun.nio.cs.StreamDecoder.readBytes(Unknown Source)
	at sun.nio.cs.StreamDecoder.implRead(Unknown Source)

	at java.io.BufferedReader.readLine(Unknown Source)
	at java.io.BufferedReader.readLine(Unknown Source)
	at 通信软件服务器.Demo.main(Demo.java:24)

 

原因分析:

   客户端在连接到服务器之后就已经被虚拟机回收了

 

 

解决思路;

  1,在客户端中关闭流

          客户端在连接到服务器之后,流必须发送字符串之后才能被关闭和回收

       

   bdw.close();

 

 

 2,在发送的字符串穿件分割符;

     在发送字符串的时候添加分隔符,告诉服务器一行的结束位置;  \r\n是换行符

       

   String text="您好\r\n";

 

修改后的代码;

服务器

package 通信软件服务器;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class Demo {

	public static void main(String[] args) {
		try {
			ServerSocket server = new ServerSocket(9090);
			System.out.println("等待客户端连接");
			Socket socket = server.accept();
			System.out.println(socket.getRemoteSocketAddress() + "连接上服务器");
		   
			InputStream is = socket.getInputStream();
			InputStreamReader isr = new InputStreamReader(is);
			BufferedReader bis = new BufferedReader(isr);
//			int a=bis.read();
//			System.out.println(a);
			//readLine()必须要有结束的标志\r\n
			String line = bis.readLine();
			System.out.println("line:" + line);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

}

 

   

客户端;

package 通信软件服务器;

import java.io.BufferedWriter;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.Socket;

public class SocketDemo {
	//private static String text="您好";

	public static void main(String[] args) {
		 //Connection reset 连接被重置
		try{
		//创建套接字的连接对象
		Socket socket = new Socket("127.0.0.1",9090);
		OutputStream os = socket.getOutputStream();
		OutputStreamWriter osw = new OutputStreamWriter(os);
		BufferedWriter bdw = new BufferedWriter(osw);
		//
		String text="您好\n\r";
		bdw.write(text, 0, text.length());
		bdw.flush();
	    bdw.close();
		}catch(Exception e){
			e.printStackTrace();
		}
	}
}

 

执行结果:

等待客户端连接
/127.0.0.1:53633连接上服务器
line:您好
