request 请求转发

package request;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

//request请求转发，以及使用request域对象吧数据带给转发资源
public class RequestDemo5 extends HttpServlet {
    //用congtext存数据是行不通的，但是request存数据是可以的，每个请求对象都有唯一的request
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String data = "aaaaaa";
        request.setAttribute("data", data);
        //request也可实现转发
        request.getRequestDispatcher("/message.jsp").forward(request, response);
    }
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doGet(request, response);
    }
