servlet上传图片服务器路径

1.在servlet中上传图片,上传的文件夹是imge在webroot下,主要代码如下

private void saveImage(HttpServletRequest request, HttpServletResponse response) throws IOException  {   
        //保存的图片的名称  
        fileName =System.currentTimeMillis() + ".jpg";    
       //获得imge文件夹在tomcat中的决定路径，basePath的值是C:Program FilesApache Software FoundationApache Tomcat 6.0.20webappsflexTestimge  
        String basePath = request.getSession().getServletContext().getRealPath("/imge/");  
        filePath = basePath;  
        System.out.println("保存图片的地址为："+filePath);  
        realFilePath = filePath+"\"+fileName;  
        // 获得一个图片文件流，我这里是从flex中传过来的  
        BufferedImage bufferedImage = ImageIO.read(request.getInputStream());    
       if (bufferedImage != null) {    
           //保存图片到指定的目录和文件中  
           ImageIO.write(bufferedImage, "jpeg", new File(filePath , fileName));    
       }    
   }

2.当要把上面上传图片通过servlet展示到游览器上时，取的路径如下：

    private void printImage(HttpServletRequest request, HttpServletResponse response) throws IOException  {     
            response.setContentType("text/html");  
            request.setCharacterEncoding("utf-8");  
            PrintWriter out = response.getWriter();  
            //获得服务器的地址，不能直接获取本机tomcat的绝对路径，不然游览器读取不了指定的图片文件  
            // basePath的值是http://localhost:8080/flexTest  
            String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+request.getContextPath()+"/";  
            String showFile = basePath+"/imge/"+this.fileName;  
            out.println("<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">");  
            out.println("<HTML>");  
            out.println("  <HEAD><TITLE>A Servlet</TITLE></HEAD>");  
            out.println("  <BODY>");  
            out.print("    This is ");  
            out.print(" <img src="+showFile+">");  
            out.print("</img>");  
            System.out.println("有显示图片的地址是"+showFile);  
           //showFile的值是    http://localhost:8080/flexTest//imge/1299470395060.jpg  
            out.println(", using the POST method");  
            out.println("  </BODY>");  
            out.println("</HTML>");  
            out.flush();  
            out.close();  
       }
