使用会话显示表单数据的java beans

// Java Bean类
public class FormDataBean {
    private String name;
    private String email;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }
}

// 表单提交处理程序
public class FormSubmitServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // 创建Java Bean对象
        FormDataBean formData = new FormDataBean();

        // 从表单获取数据并填充Java Bean对象
        formData.setName(request.getParameter("name"));
        formData.setEmail(request.getParameter("email"));

        // 将Java Bean对象存储在会话中
        HttpSession session = request.getSession();
        session.setAttribute("formData", formData);

        // 重定向到显示数据的页面
        response.sendRedirect("display.jsp");
    }
}

// 显示数据的页面
public class DisplayServlet extends HttpServlet {
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // 从会话中获取Java Bean对象
        HttpSession session = request.getSession();
        FormDataBean formData = (FormDataBean) session.getAttribute("formData");

        // 在页面上显示表单数据
        response.getWriter().println("Name: " + formData.getName());
        response.getWriter().println("Email: " + formData.getEmail());
    }
}
