用JavaBean實現文件上載(一)

請求分析 　　表單的action屬性值是Jsp1.jsp，這意味著請求（包括上載的文件）將發送給Jsp1.jsp文件。JSp1.JSP簡單地調用名為SimpleBean的JavaBean。 <% TheBean.doUpload(request); %>　　下面是SimpleBean的實現代碼： import java.io.*; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import Javax.servlet.ServletInputStream; public class FileUploadBean { public void doUpload(HttpServletRequest request) throws IOException { PrintWriter pw = new PrintWriter( new BufferedWriter(new FileWriter("Demo.out"))); ServletInputStream in = request.getInputStream(); int i = in.read(); while (i != -1) { pw.print((char) i); i = in.read(); } pw.close(); } }
