如何在java中实现同一会话的get和post方法

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 doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // 处理GET请求的逻辑
        // 可以通过request.getParameter()方法获取GET请求中的参数
        String param1 = request.getParameter("param1");
        String param2 = request.getParameter("param2");

        // 返回响应
        response.getWriter().println("GET请求处理结果");
    }

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // 处理POST请求的逻辑
        // 可以通过request.getParameter()方法获取POST请求中的参数
        String param1 = request.getParameter("param1");
        String param2 = request.getParameter("param2");

        // 返回响应
        response.getWriter().println("POST请求处理结果");
    }
}
