直接跳轉到hello.html頁面 response_demo03.jsp
| 代碼如下 | 複製代碼 |
<%@ page language="java" contentType="text/html" pageEncoding="GBK"%> <html> <head> <title>測試</title> </head> <body> <% response.sendRedirect("hello.html"); %> </body> </html> |
|
這種跳轉屬於用戶端跳轉
<jsp:forward>屬於服務端跳轉,地址不會發生改變,可以將request屬性儲存到跳轉頁
response.sendRedirect()屬於用戶端跳轉,地址會發生改變,不可以將request屬性儲存到跳轉頁
還有一個區別就是:服務端跳轉會立刻跳轉,而用戶端跳轉在整個頁面執行完後才進行跳轉
