1.跳转功能的实现
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP 'Jsp5.jsp' starting page</title>
</head>
<body>
<%
pageContext.forward("/index.jsp");
%>
</body>
</html>
2.跳转的时候带参数:
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP 'Jsp6.jsp' starting page</title>
</head>
<body>
<!--
//测试时把下面的代码删除
<jsp:forward page="/index.jsp"></jsp:forward>
<jsp:include page="/public/head.jsp"></jsp:include> //与PageContext.include()一样是动态包含
-->
<jsp:forward page="/ServletDemo1">
<jsp:param name="data" value="XXX"></jsp:param>
</jsp:forward>
</body>
</html>
ServletDemo1:
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class ServletDemo1 extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=UTF-8");
PrintWriter out=response.getWriter();
String data=request.getParameter("data");
out.write("JSP传过来的数据是：");
out.write(data);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request,response);
}
}
最后在Servlet上拿到jsp文件跳转时传过来的参数。
