package servlet;
import java.io.IOException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet(name = "saveServlet", urlPatterns = { "/saveServlet" })
public class SaveServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {

}
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
String names[] = { "zhao", "qian", "sun", "li" };
request.setAttribute("name", names);
RequestDispatcher dis = request.getRequestDispatcher("show.jsp");
dis.forward(request, response);
}
}
3.show.jsp里面的代码如下所示：
<%@page import="java.util.Date"%>
<%@ page language="java" contentType="text/html; charset=UTF-8"

</head>
<body>
从servlet转发过来的request内置对象的数据如下：
<br> ${requestScope.name[0] }
<br> ${requestScope.name[1] }
<br> ${requestScope.name[2] }
<br> ${requestScope.name[3] }
<br>
</body>
