这个在servlet中但是运用转发完成参数通报
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>经由过程request对象取值</h5> 账号:<%=request.getAttribute("username") %> 暗码:<%=request.getAttribute("password") %> <P>=======================</P> <h5>经由过程EL表达式取值</h5> 账号:${username} 暗码:${password} </body> </html>
