我使用SpringMVC、JPA(Hibernate)和Jsp设计了一个登录页面

请查找login.jsp:-

    <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
        pageEncoding="ISO-8859-1"%>
    <%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <body>
        <h2>Login page</h2>
        <form:form method="POST" modelAttribute="loginBean" action="showProfile">
            <table>
                <tr>
                    <td>UserName :<form:input path="userName"/></td>
                </tr>
                <tr>
                    <td>Organization Id :<form:input path="OrgId" /></td>
                </tr>
                <tr>
                    <td>Password : <form:input path="password" /></td>
                </tr>
                <tr>
                    <td colspan="2"><input type="submit" value="Submit" /></td>
                </tr>
            </table>
        </form:form>
    </body>
    </html> 
在Login.jsp页面中给出有效的详细信息后,它将重定向到profilePage.jsp,但profilePage.jsp中的数据不正确。请帮助我理解我在哪里犯了错误

profilePage.jsp显示在以下位置:-

用户名密码 ${staff.userName}${staff.password}


未显示此变量的值。

profilePage.jsp:page指令中的Add
isaligned=“false”

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
        pageEncoding="ISO-8859-1" isELIgnored="false"%>

profilePage.jsp:在页面指令中添加
isaligned=“false”

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
        pageEncoding="ISO-8859-1" isELIgnored="false"%>

这是行不通的。它只是显示用户名密码。这不起作用。它只是显示用户名和密码
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
        pageEncoding="ISO-8859-1" isELIgnored="false"%>
@Controller
