直接上浏览器端upload.jsp代码（为测试服务器端）
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>upload</title>
</head>
<body>
<center>
<!-- /Myweb/upload.do -->
<form action="${pageContext.request.contextPath}/upload.do" method="post" enctype="multipart/form-data">
<table>
<tr>
<td>

<td>
<input type="text" name="Name">

</table>
</form>
</center>
</body>
</html>
<form action="${pageContext.request.contextPath}/upload.do" method="post" enctype="multipart/form-data"> 注意enctype="multipart/form-data" （复杂的数据提交）和{pageContext.request.contextPath}/upload.do工程访问路径
还有就是字符集统一使用utf-8 小心中文乱码。
2.服务器端，采用commons-fileupload 来实现文件上传，仍然使用Servlet
commons-fileupload-1.3.1.jar+ commons-io-2.4.jar（本人出现兼容报错）
代码如下
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
//判断是否是复杂表单提交
boolean isMutipart=ServletFileUpload.isMultipartContent(request);
//
if(isMutipart)
{
//配置缓存工厂
DiskFileItemFactory factory=new DiskFileItemFactory();
//设置缓存大小
factory.setSizeThreshold(1024*1024*2);
File temp=new File("D:\\temp");
if (!temp.exists()) {
temp.mkdir();
}
factory.setRepository(temp);
ServletFileUpload upload=new ServletFileUpload(factory);
// upload.setHeaderEncoding("utf-8");
upload.setFileSizeMax(1024*1024*5);
upload.setSizeMax(1024*1024*6);
//获取提交的集合
try {
List<FileItem>items=upload.parseRequest(request);
if(items!=null)
{
for(FileItem item :items)
{
if(item.isFormField())
{
//一般数据
System.out.println(item.getFieldName());
System.out.println(item.getString("utf-8"));
}
else {
String pathString=item.getName();
if(pathString.contains("\\"))
{
int index=pathString.lastIndexOf("\\");
pathString=pathString.substring(index+1);
}
System.out.println(pathString);
//复杂文件
try {
item.write(new File("D:\\"+pathString));
response.getWriter().write("upload success!");
} catch (Exception e) {
e.printStackTrace();
response.getWriter().write("upload fail.");
}
}
}
}
} catch (FileUploadException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else {
return;
}
}
