一个简单的管理员登录后跳转到JSP页面的示例,通常会涉及HTML表单、Servlet处理登录请求以及转发到特定页面。这里是一个基础的步骤:
1. 创建登录表单 (login.jsp):
```html
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<title>Admin Login</title>
</head>
<body>
<form action="LoginServlet" method="post">
<label for="username">Username:</label>
<input type="text" id="username" name="username"><br>
<label for="password">Password:</label>
<input type="password" id="password" name="password"><br>
<input type="submit" value="Login">
</form>
</body>
</html>
```
2. 创建登录处理Servlet (LoginServlet.java):
```java
import javax.servlet.*;
import java.io.IOException;
@WebServlet("/LoginServlet")
public class LoginServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String username = request.getParameter("username");
String password = request.getParameter("password");
// 这里只是一个模拟,实际应用需要连接数据库验证用户名密码
if ("admin".equals(username) && "admin_password".equals(password)) {
HttpSession session = request.getSession();
session.setAttribute("loggedIn", true);
// 跳转到管理界面
response.sendRedirect("dashboard.jsp");
} else {
response.sendRedirect("error.jsp?msg=Invalid credentials");
}
}
}
```
3. 登录成功后显示的管理员界面 (dashboard.jsp):
```html
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<title>Admin Dashboard</title>
<!-- 这里假设管理员已经有权限访问 -->
</head>
<body>
Welcome, Admin! <a href="logout.jsp">Logout</a>
</body>
</html>
```
