数据库存入html怎么读取

读出二进制，转化成流，然后write到页面上

byte[] blob = userinfo.getPhoto()

if(blob!=null){

response.reset() response.setContentType("image/"+dat) OutputStream toClient = response.getOutputStream() try {toClient.write(blob) } catch (Exception e) {e.printStackTrace() }finally{toClient.flush() toClient.close() } response.flushBuffer() }

写数据库

byte[] bFile = new byte[(int) files[0].length()]FileInputStream fileInputStream = new FileInputStream(files[0])fileInputStream.read(bFile)fileInputStream.close()userinfo.setPhotoname(photoName[0])userinfo.setPhoto(bFile)

userdao.save(userinfo)

我这个是java的，不知道和你的一不一样

简单实现：

HtmlRequest类的内容：

[java] view plaincopy

package com.capinfotech.net

import java.io.ByteArrayOutputStream

import java.io.IOException

import java.io.InputStream

import java.net.HttpURLConnection

import java.net.URL

public class HtmlRequest {

public static void main(String[] args) throws IOException {

URL url = new URL("http://www.163.com/")

HttpURLConnection conn = (HttpURLConnection)url.openConnection()

InputStream inputStream = conn.getInputStream() //通过输入流获得网站数据

byte[] getData = readInputStream(inputStream)//获得网站的二进制数据

String data = new String(getData, "gb2312")

System.out.println(data)

}

public static byte[] readInputStream(InputStream inputStream) throws IOException {

byte[] buffer = new byte[1024]

int len = 0

ByteArrayOutputStream bos = new ByteArrayOutputStream()

while((len = inputStream.read(buffer)) != -1) {

bos.write(buffer, 0, len)

}

bos.close()

return bos.toByteArray()

}

}

这样就能获得http://www.163.com的内容，在控制台会打印输出
