request域读写数据和请求转发

package com.ithiema.forward;
import java.io.IOException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class Servlet1 extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//想request域中存储数据
request.setAttribute("name", "tom");
//servlet1 将请求转发给servlet2
RequestDispatcher dispatcher = request.getRequestDispatcher("/servlet2");
//执行转发的方法
dispatcher.forward(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
