此時(shí)的服務(wù)器還在等待輸入，客戶端也在等待服務(wù)器的應(yīng)答，產(chǎn)生死鎖，僵持不下。

經(jīng)過(guò)一番嘗試后發(fā)現(xiàn)，

當(dāng)使用單行讀取的時(shí)候，使用bufferedWriter.newLine();此時(shí)就不用關(guān)閉socket的輸出流，即socket.shutdownOutput();可以省略，當(dāng)然寫(xiě)上去也沒(méi)錯(cuò)。

當(dāng)使用多行讀取的時(shí)候，此時(shí)，必須使用關(guān)閉socket的輸出流，即socket.shutdownOutput();不能省略?。?！

單行接受代碼如下：?

這是Client：?

 //現(xiàn)在向Server發(fā)送信息
        OutputStream outputStream = socket.getOutputStream();
        BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream));
        bufferedWriter.write("Hello,server 字符流");
        bufferedWriter.newLine();
        /**插入換行符后,相當(dāng)于寫(xiě)入結(jié)束，就不用socket.shutdownOutput();
        此時(shí)對(duì)面一定要使用readLine()一次讀一行代表讀取結(jié)束*/
        bufferedWriter.flush();
        socket.shutdownOutput();//可以省略，加上不為錯(cuò)

這是Server端：?

//接受Client的輸入信息
        String read =null;
        InputStream inputStream = socket.getInputStream();
        BufferedReader bufferedReader =new BufferedReader(new InputStreamReader(inputStream));
        String s = bufferedReader.readLine();
        System.out.println(s);
        socket.shutdownInput();

多行讀取時(shí)：

這是Client端：?

 //現(xiàn)在向Server發(fā)送信息
        OutputStream outputStream = socket.getOutputStream();
        BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream));
        bufferedWriter.write("Hello,server 字符流");
        bufferedWriter.newLine();
        /**插入換行符后,相當(dāng)于寫(xiě)入結(jié)束，就不用socket.shutdownOutput();
        此時(shí)對(duì)面一定要使用readLine()一次讀一行代表讀取結(jié)束*/
        bufferedWriter.flush();
        socket.shutdownOutput();//一定不能省略

?這是Server端：文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-734549.html

       //接受Client的輸入信息
        String read =null;
        InputStream inputStream = socket.getInputStream();
        BufferedReader bufferedReader =new BufferedReader(new InputStreamReader(inputStream));
        while ((read= bufferedReader.readLine())!=null){
            System.out.println(read);
        }
        socket.shutdownInput();//不可省

到了這里，關(guān)于當(dāng)在本地，向服務(wù)器發(fā)送信息時(shí)，服務(wù)器接受信息返回給客戶端，此時(shí)采用多行讀取時(shí)，客戶端接收不到Server的信息的文章就介紹完了。如果您還想了解更多內(nèi)容，請(qǐng)?jiān)谟疑辖撬阉鱐OY模板網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章，希望大家以后多多支持TOY模板網(wǎng)！
