使用转发来给jsp页面赋值。具体操作如下：
这个在servlet中可是使用转发实现参数传递
protected void doget(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception { // todo auto-generated method stub request.setcharacterencoding(utf-8); request.setattribute(username, dhweicheng); request.setattribute(password, 123456); request.getrequestdispatcher(/my.jsp).forward(request, response);}
jsp页面代码：
<%@ page language="java" contenttype="text/html; charset=utf-8" pageencoding="utf-8"%><!doctype html public "-//w3c//dtd html 4.01 transitional//en" "http://www.w3.org/tr/html4/loose.dtd"><html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <title>页面代码</title> </head> <body> <h5>通过request对象取值</h5> 账号:<%=request.getattribute("username") %> 密码:<%=request.getattribute("password") %> <p>=======================</p> <h5>通过el表达式取值</h5> 账号:${username} 密码:${password} </body></html>
以上就是java怎么给jsp页面赋值的详细内容。
