2 服务端代码 新建一个servlet，修改 dopost代码
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
Date date = new Date();//获取当前时间
SimpleDateFormat sdfFileName = new SimpleDateFormat("yyyyMMddHHmmss");
//SimpleDateFormat sdfFolder = new SimpleDateFormat("yyMM");
String newfileName = sdfFileName.format(date);//文件名称
String fileRealPath = "";//文件存放真实地址
String firstFileName="";
// 获得容器中上传文件夹所在的物理路径 如果按日期存放，则可以在files\\后面继续加 sdFolder+"\\"
String savePath = this.getServletConfig().getServletContext().getRealPath("/") + "files\\";
/* System.out.println("路径" + savePath+"; name:"+name); */
System.out.println("路径" + savePath);
File file = new File(savePath);
if (!file.isDirectory()) {
file.mkdirs();
}
try {
DiskFileItemFactory fac = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(fac);
upload.setHeaderEncoding("UTF-8");
// 获取多个上传文件
List fileList = fileList = upload.parseRequest(request);
// 遍历上传文件写入磁盘
Iterator it = fileList.iterator();
while (it.hasNext()) {
FileItem obit = (FileItem)it.next();
//如果是普通 表单参数
if(obit.isFormField()){ //普通域,获取页面参数
String field = obit.getFieldName();
if(field.equals("value1"))
{
System.out.println(obit.getString("UTF-8"));
}
else if(field.equals("value2")){
System.out.println(obit.getString("UTF-8"));
}
}
// 如果是 多媒体
if(obit instanceof DiskFileItem){
DiskFileItem item = (DiskFileItem) obit;
// 如果item是文件上传表单域
// 获得文件名及路径
String fileName = item.getName();
if (fileName != null) {
firstFileName=item.getName().substring(item.getName().lastIndexOf("\\")+1);
String formatName = firstFileName.substring(firstFileName.lastIndexOf("."));//获取文件后缀名
fileRealPath = savePath + newfileName + formatName;//文件存放真实地址
BufferedInputStream in = new BufferedInputStream(item.getInputStream());// 获得文件输入流
BufferedOutputStream outStream = new BufferedOutputStream(new FileOutputStream(new File(fileRealPath)));// 获得文件输出流
Streams.copy(in, outStream, true);// 开始把文件写到你指定的上传文件夹
//上传成功，
if (new File(fileRealPath).exists()) {
//虚拟路径赋值
// fileRealResistPath=sdfFolder.format(date)+"/"+fileRealPath.substring(fileRealPath.lastIndexOf("\\")+1);
//保存到数据库
System.out.println("上传成功了， 您还可以做其他操作");
//System.out.println("虚拟路径:"+fileRealResistPath);
response.getWriter().write(fileRealPath.substring(fileRealPath.lastIndexOf("\\")+1));
}
}
}
}
} catch (org.apache.commons.fileupload.FileUploadException ex) {
ex.printStackTrace();
System.out.println("没有上传文件");
return;
}
/* response.getWriter().write("1"); */
}
data-ajax="false" 是重点，终于解决了
