要实现基于Java Web的学生管理系统，可以按照以下步骤：

首先需要创建数据库表格，包括学生信息的各个字段，例如学生ID、姓名、性别、年龄、班级等。 创建一个JavaBean类，用来存储学生信息，包括各个字段的setter和getter方法。 创建一个DAO层，用来对数据库进行增删查改操作，包括添加学生、删除学生、查询学生、更新学生信息等。 创建一个Servlet层，用来接收前端请求，将请求参数传递给DAO层进行数据库操作，并将操作结果返回给前端。 创建一个JSP页面，用来展示学生信息、添加学生、修改学生信息等。 6. 部署应用 将应用部署到服务器上，例如Tomcat服务器，让用户可以通过浏览器访问学生管理系统。 具体实现方法可以参考以下示例代码： ```sql CREATE TABLE student ( id INT PRIMARY KEY AUTO_INCREMENT, name VARCHAr(20), gender VARCHAr(10), age INT, class VARCHAr(20) ); public class Student { private int id; private String name; private String gender; private int age; private String clazz; // setter and getter methods public class StudentDAO { private static final String URL = "jdbc:mysql://localhost:3306/studentdb"; private static final String USERNAME = "root"; private static final String PASSWORD = "root"; public void addStudent(Student student) { PreparedStatement ps = conn.prepareStatement("INSERT INTO student(name, gender, age, class) VALUES (?, ?, ?, ?)")) { public void deleteStudent(int id) { PreparedStatement ps = conn.prepareStatement("DELETE FROM student WHERe id = ?")) { public Student getStudentById(int id) { PreparedStatement ps = conn.prepareStatement("SELECt * FROM student WHERe id = ?")) { if (rs.next()) { return student; return null; public List<Student> getAllStudents() { List<Student> students = new ArrayList<>(); PreparedStatement ps = conn.prepareStatement("SELECt * FROM student")) { while (rs.next()) { students.add(student); return students; public void updateStudent(Student student) { PreparedStatement ps = conn.prepareStatement("UPDATE student SET name = ?, gender = ?, age = ?, class = ? WHERe id = ?")) { ps.setInt(5, student.getId()); public class StudentServlet extends HttpServlet { private StudentDAO studentDAO = new StudentDAO(); protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { if ("add".equals(action)) { addStudent(request, response); } else if ("delete".equals(action)) { deleteStudent(request, response); } else if ("update".equals(action)) { updateStudent(request, response); protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { if ("list".equals(action)) { listStudents(request, response); } else if ("edit".equals(action)) { editStudent(request, response); private void addStudent(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { studentDAO.addStudent(student); private void deleteStudent(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { studentDAO.deleteStudent(id); private void updateStudent(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { student.setId(id); studentDAO.updateStudent(student); private void listStudents(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { List<Student> students = studentDAO.getAllStudents(); request.setAttribute("students", students); request.getRequestDispatcher("list.jsp").forward(request, response); private void editStudent(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { Student student = studentDAO.getStudentById(id); request.setAttribute("student", student); request.getRequestDispatcher("edit.jsp").forward(request, response); ```jsp <!-- list.jsp --> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <table border="1"> <thead> <th>ID</th> <th>姓名</th> <th>性别</th> <th>年龄</th> <th>班级</th> <th>操作</th> </thead> <tbody> <c:forEach items="${students}" var="student"> <td>${student.id}</td> <td>${student.name}</td> <td>${student.gender}</td> <td>${student.age}</td> <td>${student.clazz}</td> <td> <a href=https://blog.csdn.net/qq_40395100/article/details/"student?action=edit&id=${student.id}">编辑</a> <a href=https://blog.csdn.net/qq_40395100/article/details/"student?action=delete&id=${student.id}">删除</a> </td> </c:forEach> </tbody> </table> <a href=https://blog.csdn.net/qq_40395100/article/details/"add.jsp">添加学生</a> <!-- edit.jsp --> <input type="hidden" name="action" value="update"> <input type="hidden" name="id" value="${student.id}"> 姓名：<input type="text" name="name" value="${student.name}"><br> 性别：<input type="radio" name="gender" value="男" ${student.gender == '男' ?
