使用socket java无法在send文件中获取接收文件循环 [英] Can't get out the receive file loop in send file using socket java

问题描述

我正在开发客户端 - 服务器应用程序。从客户端，我将文件发送到服务器。
这是我在服务器上读取文件的代码：

I am developing client-server app. From client, I send a file to server. Here is my code about read file at server:

    private void readfile() throws Exception{
            String filename="data.xml";
    FileOutputStream fos = new FileOutputStream(filename);
    BufferedOutputStream out = new BufferedOutputStream(fos);
    BufferedReader buff_read = new BufferedReader(new InputStreamReader(input,"UTF-8"));
    byte[] buffer=new byte[1024];
    String line;
    int count;
    while((count=input.read(buffer))>0){
        fos.write(buffer,0,count);
        fos.flush();
    }
    System.out.println("het");
    fos.close();
}

但我无法摆脱while循环。字符串hetnerver在控制台屏幕显示，而我可以通过记事本++读取文件data.xml意味着文件发送成功。
你能帮我解决这个问题。
对不起我糟糕的英语。

But I can't get out of the while loop. String "het" nerver show in console screen while I can read file data.xml by notepad++ mean that the file sent success. Can you help me solve this problem. Sorry for my poor Englisg.

推荐答案

read（）方法在流结束时返回-1，套接字表示对等方已关闭连接。如果你没有得到-1，则对等体没有关闭连接。

The read() method returns -1 at end of stream, which for a socket means the peer has closed the connection. If you're not getting -1, the peer isn't closing the connection.
