<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Test</title> </head> <body> <form action="com/servlet/LoginServlet" method="post"> <table> <tr> <td>用户名：</td> <td><input type="text" name="username"></td> </tr> <tr> <td>密码：</td> <td><input type="password" name="password"></td> </tr> <td> <td><input type="submit" value="登录" /></td> </tr> </table> </form> </body> </html>
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>LoginSuccess</title> </head> <body> <h1>登录成功！</h1> <jsp:useBean id="loginuser" class="com.entity.User" scope="session" /><br> 欢迎您，<jsp:getProperty name="loginuser" property="username">!<br> </body> </html>
@WebServlet(name = "LoginServlet")
public class LoginServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
String username = request.getParameter("username");
String password = request.getParameter("password");
User user = new User();
user.setUsername(username);
user.setUsername(password);
request.getSession().setAttribute("loginuser",user);
if(username.equals("admin")&&password.equals("admin")){
response.sendRedirect(request.getContextPath()+"/loginSuccess.jsp");
}
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request,response);
}
}为什么我这登录页面总是跳转不到成功页面呢？
但是系统总是报这行代码错误：
<jsp:getProperty name="loginuser" property="username">
