从版本6开始，Java SE提供了JAXB，通过它可以将 字节 转换为 base64 string 。在这里，您还可以将图像
byte[]转换为以
64 为 基数的字符串 ，并且可以使用
<imghtml
标记显示该图像，将src数据指定为以64为基数，即
select * from artist"); ResultSet rs=ps.executeQuery(); while(rs.next()){ %> <table><tr><th>artist fast name:</th><td><%=rs.getString(1) %></td></tr> <tr><th>artist middle name:</th><td><%=rs.getString(2) %></td></tr> <tr><th>artist last name</th><td><%=rs.getString(3) %></td></tr> <tr><th>artist job</th><td><%=rs.getString(4) %></td></tr> <tr><th>artist image</th><td> <% Blob bl=rs.getBlob(5); byte[] image=bl.getBytes(1, (int)bl.length()); %> <img height="100" width="100" alt="bye"/> </td></tr> </table> <% } con.close(); %>这是另一个清晰的 jsp 示例页面：
<%@page import="java.awt.image.BufferedImage"%><%@page import="javax.imageio.ImageIO"%><%@page import="java.io.*"%><%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title>Insert title here</title></head><body><%BufferedImage bImage = ImageIO.read(new File("/home/visruth/Desktop/Visruth.jpg"));//give the path of an imageByteArrayOutputStream baos = new ByteArrayOutputStream();ImageIO.write( bImage, "jpg", baos );baos.flush();byte[] imageInByteArray = baos.toByteArray();baos.close();String b64 = javax.xml.bind.DatatypeConverter.printbase64Binary(imageInByteArray);%><div> <p>As of v6, Java SE provides JAXB</p> <img alt="Visruth.jpg not found" /></div> </body></html>
