webservice 图片传输 服务端

/**xml * String类型转为xml */ SAXReader saxReader = new SAXReader(); org.dom4j.Document document; document = saxReader.read(new ByteArrayInputStream(xml.getBytes())); org.dom4j.Element incomingForm = document.getRootElement(); /** * 创建xml文件 */ OutputFormat format= OutputFormat.createPrettyPrint();//美化格式 format.setEncoding("UTF-8");//设置字符编码 XMLWriter write = new XMLWriter(new FileWriter(new File("src/createhouse.xml")),format); write.write(incomingForm); write.flush(); write.close(); System.out.println("创建createhouse.xml完毕!");

服务端接收string类型 生成xml文件

?

服务Element housesub1=item.getChild("housePictureslist").getChild("housePicture").getChild("housePicInfo"); String housePic=housesub1.getText(); byte[] imgByte = hex2byte(housePic); InputStream in = new ByteArrayInputStream(imgByte); byte[] b = new byte[1024]; FileOutputStream fos=new FileOutputStream("WebRoot/upload/pictures/house/"+housePicTimeName+".jpg"); int nRead1 = 0; while( ( nRead1 = in.read(b) ) != -1 ){ fos.write( b,nRead1 ); } fos.close();

服务端读取生成的xml里面图片信息 生成图片

?

?

File file=new File("WebRoot/upload/pictures/house/" + housePic.getPicTimeName()); System.out.println(file+"图片路径"); if(file.exists() && file.isFile()) file.delete();

housePic是根据某个ID查出的那条图片信息

?删除图片
