用JavaBean实现文件上载(一)

成骏针织机械

请求分析 　　表单的action属性值是Jsp1.jsp，这意味着请求（包括上载的文件）将发送给Jsp1.jsp文件。Jsp1.jsp简单地调用名为SimpleBean的JavaBean。 　
　下面是SimpleBean的实现代码：
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();
}
}
