本地文件上传到服务器指定位置

首先导入commons-fileupload-1.2.1.jar和commons-io-1.3.2.jar

PrintWriter out=response.getWriter();
DiskFileUpload fu = new DiskFileUpload();
fu.setSizeMax(1024 * 1024 * 200);                 //最大为200G
fu.setSizeThreshold(1024 * 1024);                 //每次上传不能超过1G
String fileurl = WebConst.DBBACKPATH_TEMP;
String fileName =null;
       try {
        //开始读取上传的信息
List fileItems = fu.parseRequest(request);     
Iterator i = fileItems.iterator();
String filePath = null;

//处理每个表单的字段
while (i.hasNext()) {
FileItem fi = (FileItem) i.next();

if (fi.isFormField()) {
String content = fi.getString("gb2312");
request.setAttribute(fi.getFieldName(), content);
         }
         else {
       try {
         String pathSrc = fi.getName();
int start = pathSrc.lastIndexOf("\\");
fileName = pathSrc.substring(start + 1);
File file = new File(fileurl, fileName);
fi.write(file);
} catch (Exception e) {
}
}

}

} catch (FileUploadException e) {
e.printStackTrace();
}
