java - 异常 java.net.SocketException : Connection reset

Question

我编写了一段代码来解析来自代理服务器的 csv 文件。但是在特定时间间隔后(解析一些 csv 行后)，它给出了此错误:

DEBUG [csvFile-267] Successfully parsed usage CSV file for 30 rows
ERROR  [csvFile-271] Exception occurred in csvFile() 
java.net.SocketException: Connection reset
at java.net.SocketInputStream.read(SocketInputStream.java:196)
at java.net.SocketInputStream.read(SocketInputStream.java:122)  

当我在该服务器上执行 ping 操作时，在某些情况下会遇到“请求超时”的情况。这是服务器配置问题、网络问题还是编码问题？

我的代码:

    while ((line = reader.readLine()) != null) {
            UsageResponse usageResponse = new UsageResponse();
            ErrorDetails errorDetails = new ErrorDetails();
            try {
                //fileData = line.split(splitby);
                fileData = line.split(",(?=([^\"]*\"[^\"]*\")*[^\"]*$)");

                if (isheaderReadable) {

                    for (int headerCounter = 0; headerCounter < fileData.length; headerCounter++) {
                        if (fileData[headerCounter].equalsIgnoreCase(Constants.DAILY_USAGE_REPORT_START_DATE)) {
                            usageStartDateLocation = headerCounter;
                        } else if (fileData[headerCounter].equalsIgnoreCase(Constants.DAILY_USAGE_REPORT_END_DATE)) {
                            usageEndDateLocation = headerCounter;
                        } else if (fileData[headerCounter].equalsIgnoreCase(Constants.DAILY_USAGE_ACCOUNT_ID)) {

如果您正在 ping 服务器并收到请求超时，则意味着您正在 ping 的任何内容都没有收到您的 ping。此外，由于错误消息指出连接已重置，这可能表明服务器失去了与您的应用程序的连接。简而言之，与服务器的连接已建立，但是当您开始与服务器通信时，它会重置连接。

对此持保留态度，因为您提供的代码似乎不是处理套接字本身的原始代码，所以我不能代表代码发言。

Tldr；服务器超时，因此连接正在重置。也可能是实际处理套接字的代码
