使用JAVA技术实现文件的上传

            if (null!=name)
            {
                if(buffer.size()>2)

                    FileOutputStream outStream = new FileOutputStream(strDir+filename);
                    outStream.write(buffer.toByteArray(), 0, buffer.toByteArray().length);
                    outStream.close();
                }
                name=null;
                value=null;
                filename=null;
                contentType=null;
                buffer=new ByteArrayOutputStream();
            }
        }//end of st.startsWith(boundary)
        else if (st.startsWith("Content-Disposition: form-data") && state==0)
