从特定URL下载pdf时出现“ java.net.SocketException：连接重置”异常

如何解决从特定URL下载pdf时出现“ java.net.SocketException：连接重置”异常

我知道这是一个类似的问题，许多用户已经发布了。但是实际上，我没有任何完美的解决方案来解决这个问题。

我已附上我的代码和URL供参考。我正在尝试从实时URL下载pdf并将其保存在本地计算机上。我共享了两个URL。对于第一个pdf URL，该代码已成功下载。但是对于第二个pdf URL，我有一个例外。

//      String datasheeturl = "https://www.vishay.com/docs/40002/293d.pdf";
String datasheeturl = "https://www.mouser.com/datasheet/2/427/tmcm-515668.pdf";
String downloadpath = "E:\\FileDownload/test.pdf";
try {
    URL url = new URL(datasheeturl);
    InputStream inputStream = url.openStream(); // Exception occures on this line
    Files.copy(inputStream,Paths.get(downloadpath),StandardcopyOption.REPLACE_EXISTING);
} catch (Exception e) {
    e.printstacktrace();
}

这是堆栈跟踪：
