jsp输出静态的图片

2个方式，jsp中直接输出静态图片：

 

img.jsp

<%@page import="javax.imageio.*"%>
<%@page import="java.awt.image.BufferedImage,java.io.*;"%>

<%
    File myGifFile = new File("e:\\aa\\haha.gif");
    BufferedImage bufi = ImageIO.read(myGifFile);
    response.reset();
    response.setContentType("image/gif");
    ImageIO.write(bufi, "gif", response.getOutputStream());
%>

<%@page import="javax.imageio.*"%>
<%@page import="java.awt.image.BufferedImage,java.io.*;"%>

<%
	File myGifFile = new File("e:\\aa\\haha.gif");
	BufferedImage bufi = ImageIO.read(myGifFile);
	response.reset();
	response.setContentType("image/gif");
	ImageIO.write(bufi, "gif", response.getOutputStream());
%>

 

 

img2.jsp

<%@page import="java.io.*;"%>
<%
    response.reset();
    response.setContentType("image/gif");
    response.setHeader("Cache-Control", "no-cache");
    response.setDateHeader("Expires", 0);
    java.io.FileInputStream fis = new java.io.FileInputStream(new File("e:\\aa\\haha.gif"));
    java.io.OutputStream os = response.getOutputStream();
    byte[] buf = new byte[4096];
    int bytes = 0;
    while ((bytes = fis.read(buf)) != -1)
        os.write(buf, 0, bytes);
    fis.close();
%>
