要获取common.io.jar文件，只需通过谷歌搜索它，或者直接访问Apache网站，在那里可以免费下载该文件。但请记住一件事：如果您是Windows用户，请下载二进制ZIP文件。我对每个Html表单使用公共Servlet，无论它是否有附件。 这个Servlet返回一个树状图，其中键是jsp名称参数，值是用户输入，并将所有附件保存在固定目录中，然后您可以重命名您选择的目录。我想这对你有帮助

如果您使用Geronimo及其嵌入式Tomcat，则会出现此问题的另一个根源。在这种情况下，在多次测试commons io和commons fileupload之后，问题来自处理commons xxx JAR的父类加载器。这是必须防止的。事故始终发生在：
fileItems = uploader.parseRequest(request);

为文件发送多个文件我们必须使用enctype=multipart/form data 要发送多个文件，请在输入标记中使用multiple=multiple
<form action="upload" method="post" enctype="multipart/form-data">
<input type="file" name="fileattachments" multiple="multiple"/>
<input type="submit" />
</form>
根据servlet要求编辑代码，如最大文件大小、最大请求大小和可以设置的其他选项…您可以使用jsp/servlet上载文件
<form action="UploadFileServlet" method="post">
<input type="text" name="description" />
<input type="file" name="file" />
<input type="submit" />
</form>
String loc="./webapps/prjct name/server folder/"+contentid+extension;
File uploadFile=new File(loc);
item.write(uploadFile);
下面是一个使用apache commons fileupload的示例：
// apache commons-fileupload to handle file upload
DiskFileItemFactory factory = new DiskFileItemFactory();
factory.setRepository(new File(DataSources.TORRENTS_DIR()));
ServletFileUpload fileUpload = new ServletFileUpload(factory);
List<FileItem> items = fileUpload.parseRequest(req.raw());
FileItem item = items.stream()
.filter(e ->
"the_upload_name".equals(e.getFieldName()))
.findFirst().get();
String fileName = item.getName();
item.write(new File(dir, fileName));
log.info(fileName);
如果您碰巧使用了Spring MVC，以下是如何： 我把这个留在这里，以防有人觉得有用 使用enctype属性设置为与BalusC答案相同的多部分/表格数据的表格
<form action="upload" method="post" enctype="multipart/form-data">
<input type="file" name="file" />
<input type="submit" value="Upload"/>
</form>

希望它能有所帮助：最简单的文件和输入控件方法，有10亿个库：
<%
if (request.getContentType()==null) return;
// for input type=text controls
String v_Text =
(new BufferedReader(new InputStreamReader(request.getPart("Text1").getInputStream()))).readLine();
// for input type=file controls
InputStream inStr = request.getPart("File1").getInputStream();
char charArray[] = new char[inStr.available()];
new InputStreamReader(inStr).read(charArray);
String contents = new String(charArray);
%>
首先必须将表单的enctype属性设置为multipart/formdata 如下所示

@buhake sindi hey如果我使用live server，或者通过将文件上载到服务器live server中的任何目录来运行我的项目，那么文件路径应该是什么。如果您编写代码在servlet中创建目录，那么将在live SrverNot find.jar but.zip中创建目录。你是说.zip吗？我们如何处理getPartfileattachments，以获得一个部件数组？我不认为多个文件的getPart可以工作？啊，很抱歉，我看到了request.getPartsfile，并将x_x与Servlet 3.0混淆，如果违反了MultipartConfig条件，例如：maxFileSize，调用request.getParameter返回null。这是故意的吗？如果在调用getPart并检查IllegalStateException之前获取一些常规文本参数，该怎么办？这会导致在我有机会检查IllegalStateException之前抛出NullPointerException。@BalusC我创建了一篇与此相关的文章，你知道我如何从文件API webKitDirectory检索额外信息吗。这里有更多详细信息是的，如果有人试图在tomcat 7中使用3.0部分中的代码，他们可能会遇到字符串fileName=path.getfilePart.getSubmittedFileName.getFileName.toString；中的问题MSIE fix.part类似于me@aaa：当您出于不清楚的原因使用读卡器和/或写卡器将字节转换为字符时，可能会发生这种情况。不要那样做。在读取和写入上传的文件时，在所有位置使用InputStream/OutputStream，而无需将字节转换为字符。PDF文件不是基于字符的文本文件。这是一个二进制文件。如果我没有弄错的话，这需要你在服务器的应用程序配置中配置一个bean……也许这篇文章会有所帮助：@Adam：他们从我的答案中复制了一些内容，并在上面添加了一个广告侦探，试图用它赚钱。是的，很棒的文章…不，实际上没有被复制。我写了那篇文章的第一稿以及补充代码。核心参考文档可以在这里找到：并链接到文章中引用。示例部分转载自核心参考文件，即参考点文件，即参考点文件，但并非全部。请注意，参考文件并未详细说明。谢谢您能分享选择的图片表单DBMySQL并在jsp/html上显示吗？这个解决方案是不同的。另一个解决方案是使用一个库来处理没有第三方jar文件的文件。这已经包含在当前接受的答案中。你读过了吗？自2009年12月以来，本机API已经存在。顺便说一句，你关闭溪流的方式也是一种遗产。自2011年7月推出Java7以来，您可以使用trywithresources语句，而不是在finally中处理null检查。
