如何通过对等方复制连接重置？

如何解决如何通过对等方复制连接重置？

我的服务器在日志中打印了以下内容

Caused by: java.io.IOException: Connection reset by peer

我知道客户端出于某种原因关闭了连接，但服务器仍在写入数据。而此时，客户端会返回重置标志“RST”，服务器的日志会得到Connection reset by peer

为了复制它，我让服务器休眠几秒钟，并创建了一个客户端：

 private void executePostMethod() throws IOException,InterruptedException {
        Map<String,String> responseMap = new HashMap<>();
        String data = "{\"id\":\"XYZ123\",\"name\":\"John Doe\",\"accountNumber\":\"ABC123\"}";
        URL urlObject = new URL("\"http://localhost/v1/name/validate\"");
        System.out.println("Creating Connection");
        Socket socket = new Socket(InetAddress.getByName(urlObject.getHost()),7080);
        System.out.println("Connection Established");

        PrintWriter printWriter = new PrintWriter(socket.getoutputStream());
        printWriter.println("POST " + urlObject.getFile() + " HTTP/1.0");
        printWriter.println("Host: " + urlObject.getHost());
        printWriter.println("Content-Length: " + data.length());
        printWriter.println("Content-Type: " + "application/json");
        printWriter.println();   //Writing an empty line just to notify the server the header ends here
        // and next thing written will the data/content
        printWriter.println(data);
        printWriter.println();
        printWriter.flush();
        Thread.sleep(5000);
        socket.setSoLinger(true,0);
        socket.close();
    }

在服务器发送响应之前，关闭套接字和行 socket.setSoLinger(true,0); 我相信，发送 RST 数据包。但我得到了 org.apache.catalina.connector.ClientAbortException: java.io.IOException: broken pipe 错误而不是 Connection reset by peer。

如何重现java.io.IOException: Connection reset by peer？

更新

我分析了 TCP 连接，这就是我得到的。服务器在尝试向客户端发送数据之前收到 RST 数据包

现在据我所知，如果客户端向服务器发送 RST 数据包，服务器得到 Connection reset by peer ，我只得到 broken pipe。

解决方法

这可能对任何试图找出错误及其原因的人有所帮助。

上述程序确实有效，但我发现它依赖于服务器。我在不同的服务器上尝试了上面的代码，我得到了

Caused by: java.io.IOException: Connection reset by peer
