我有Jersey提供restfull网络服务.经常发生客户端中止通过ajax完成的请求,这里解释的ajax abort方法中止了ajax请求

在服务器端,我得到以下输出.哪个不好看.有没有办法在泽西岛检测中止请求？

我们在使用 Amazon ec2 实例时特别收到此错误。aws 实例上的配置为 Tomcat 7，Ubuntu 16.04，内存为 8GB。当用户尝试查看 pdf 文件时会发生这种情况。在我们的应用程序中，我们有一项功能，用户只能在浏览器上查看 PDF 文件，但不能下载它。PDF 文件在同一台服务器上。我们正在使用 cors 最小配置。我们已经在 Ubuntu 本地尝试过它，它运行良好。

代码片段：

var fileSplitContent = fileName.split(".");
    if ($('#viewImageOnlyForm')[0] != undefined && $('#viewPdfOnlyForm')[0] != undefined) {
        if (fileSplitContent[fileSplitContent.length - 1].toLowerCase() != "pdf") {
            $('#imageSource').val(requestURL + $.param(inputData));
            $('#viewImageOnlyForm').submit();
        } else {
            var requestURL = "rest/file/getCapitalRaiseFile?";
            $('#pdFSource').val(requestURL + $.param(inputData));
            $('#viewPdfOnlyForm').submit();
        }
    } else {
        // pop up download attachment dialog box
        downloadIFrame.attr("src", requestURL + $.param(inputData));
    }

}
