Question

所以..我有一个服务器套接字，在这里：

ServerSocket server = new ServerSocket(5000);  

while(true){  
    Socket cliente = server.accept();  
    Thread thread = new Thread(new Converter(cliente));  
    thread.start();

我的应用将Word文档（.doc）转换为PDF。首先，我的服务器在收到.pdf归档后收到.doc，进行转换。

如何让客户端等待响应？

Answer 1

如果我理解正确，那么每个接受的套接字（因此客户端）都会创建一个线程。此Converter线程可以访问客户端套接字（每个客户端都有accept()返回的不同套接字）。现在解决方案非常简单：

public void run() {
    cliente.getInputStream();  //read .doc first
    //do the conversion to .pdf
    cliente.getOutputStream();  //send .pdf back
}

得到：

private void getDocArchive(){  

    try {  

        InputStream in = socket.getInputStream();  
        BufferedInputStream buffer = new BufferedInputStream(in, 1024);  

        byte[] b = new byte[1024];  
        int len = 0;  
        int bytcount = 1024;  

        FileOutputStream out = new FileOutputStream("docs/atual.doc");  

        while ((len = buffer.read(b, 0, 1024)) != -1) {  
            bytcount = bytcount + 1024;  
            out.write(b, 0, len);  
        }  

        out.flush();  

        //out.close();  
        //buffer.close();  

    } catch (IOException e) {  
        System.out.println("Ocorreu um erro no recebimento do arquivo");  
    }  
}

响应：

private void reponse() {  
    try {  
        OutputStream out = socket.getOutputStream();  
        InputStream in = new FileInputStream(pdf);  

        BufferedInputStream buffer = new BufferedInputStream(in, 1024);  

        byte[] b = new byte[1024];  
        int len = 0;  
        int bytcount = 1024;  
        int i = 0;  

        while ((len = buffer.read(b, 0, 1024)) != -1) {  
            bytcount = bytcount + 1024;  
            out.write(b, 0, len);  
        }  

        out.flush();  
        out.close();  
        buffer.close();  
    } catch (IOException e) {  
        e.printStackTrace();  
        System.out.println(e.getMessage());  
    }  
}

我的客户：

public static void main(String[] args) throws Exception {  

    try {  

        Socket client = new Socket("127.0.0.1", 5000);  

        OutputStream out = client.getOutputStream();  
        InputStream in = new FileInputStream("C:\\autistmo.docx");  

        BufferedInputStream buffer = new BufferedInputStream(in, 1024);  

        byte[] b = new byte[1024];  
        int len = 0;  
        int bytcount = 1024;  

        while ((len = buffer.read(b, 0, 1024)) != -1) {  
            bytcount = bytcount + 1024;  
            out.write(b, 0, len);  
        }  

        // resposta  

        BufferedInputStream buffer2 = new BufferedInputStream(in, 1024);  
        FileOutputStream out2 = new FileOutputStream("docs/final.doc");  

        while ((len = buffer2.read(b, 0, 1024)) != -1) {  
            bytcount = bytcount + 1024;  
            out2.write(b, 0, len);  
        }  

        out2.close();  
        buffer2.close();  

    } catch (Exception e) {  
        // TODO Auto-generated catch block  
        e.printStackTrace();  
    }

运行方法：

@Override  
public void run() {  
    getDocArchive();  
    converter();  
    reponse();  
}

mySocketClient.waitingForResponse（）或类似的？
