您自己试过吗?如果是这样的话,你能给我们看一些你是如何做到这一点的代码吗?我已经分享了我使用的代码。这些代码没有显示任何实际列出文件的尝试,这是你的上传代码。是的,但我想知道我如何做到这一点,以及何时选择任何文档,它应该在jsp iframe中显示。所以您自己甚至没有尝试过研究这个问题,您只是决定立即询问答案?它显示在控制台上,但如果我想在网页中显示?谢谢。使用ajax调用servlet,并在响应中将文件列表作为json对象写入,并在ajax成功时获得它。参考这些链接,你会得到一个想法和
File folder = new File("path/to/your/uploaded/files/directory");
File[] listOfFiles = folder.listFiles();
for (int i = 0; i < listOfFiles.length; i++) {
if (listOfFiles[i].isFile()) {
System.out.println("File " + listOfFiles[i].getName());
} else if (listOfFiles[i].isDirectory()) {
System.out.println("Directory " + listOfFiles[i].getName());
}
}
