00一、java將圖片的二進制流直接寫到前端進行展現

一、jsp 頁面html

<html xmlns="http://www.w3.org/1999/xhtml">web

<head>app

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />jsp

<title>Insert title here</title>ui

</head>url

<body>xml

 <div>htm

 

 </div>ip

 <div>get

   <img src="ImgShowServlet.servlet" alt="" />

 </div>

</body>

</html>

二、web.xml 配置

     <servlet>

    <description></description>

    <display-name>ImgShowServlet</display-name>

    <servlet-name>ImgShowServlet</servlet-name>

    <servlet-class>com.jcc.demo.img2ie.servlet.ImgShowServlet</servlet-class>

  </servlet>

  <servlet-mapping>

    <servlet-name>ImgShowServlet</servlet-name>

    <url-pattern>/ImgShowServlet.servlet</url-pattern>

  </servlet-mapping>

三、servlet代碼

   protected void service(HttpServletRequest arg0, HttpServletResponse response) throws ServletException, IOException {

     System.out.println("get the request from ie.");

     ServletOutputStream os = response.getOutputStream();

     File file = new File("D:/demo/111.jpg");

     if(file.exists()){

         BufferedImage readImg = ImageIO.read(file);

         ImageIO.write(readImg, "JPEG", os);

     }

     os.close();

 }
