后台代码：
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html");
File file1 = null;
DiskFileUpload diskFileUpload = new DiskFileUpload();
try {
List<FileItem> list = diskFileUpload.parseRequest(request);
for(FileItem fileItem : list){
if(fileItem.isFormField()){
}
else{
File remoteFile = new File(new String(fileItem.getName().getBytes(),"UTF-8")); //服务器项目部署路径_E:\tomcat\tomcat\webapps\fileUploadDemo\attachment
file1 = new File(this.getServletContext().getRealPath("attachment"),remoteFile.getName());
file1.getParentFile().mkdirs();
file1.createNewFile();
InputStream inp = fileItem.getInputStream();
OutputStream oup = new FileOutputStream(file1);
byte[] buffer = new byte[1024];
int len = 0;
while((len = inp.read(buffer)) > -1){
