如何使用servlet在两个jsp之间发送数据？

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class MyServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // 获取从前端JSP页面传递过来的数据
        String data = request.getParameter("data");

        // 根据业务逻辑对数据进行处理
        String processedData = processData(data);

        // 将处理后的数据存储到HttpServletRequest对象的属性中
        request.setAttribute("processedData", processedData);

        // 使用RequestDispatcher对象的forward方法将请求转发到下一个JSP页面
        request.getRequestDispatcher("next.jsp").forward(request, response);
    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doPost(request, response);
    }

    private String processData(String data) {
        // 在这里进行数据处理的逻辑，可以根据具体需求进行实现
        return "Processed: " + data;
    }
}
