我是靠谱客的博主怕孤单眼神，最近开发中收集的这篇文章主要介绍Servlet中获取请求行的数据，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

package priv.lwx.javaex.servlet_demo.web.servlet.request;
/**

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

@WebServlet("/request_demo01")
public class RequestDemo01 extends HttpServlet {
  @Override
  protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    String method = request.getMethod();
    System.out.println("请求方式：" + method); // 请求方式：GET
    String contextPath = request.getContextPath();
    System.out.println("虚拟目录：" + contextPath); // 虚拟目录：/servlet_demo
    String requestURI = request.getRequestURI();
    System.out.println("URI：" + requestURI); // URI：/servlet_demo/request_demo01
    String servletPath = request.getServletPath();
    System.out.println("资源路径：" + servletPath); // 资源路径：/request_demo01
    String queryString = request.getQueryString();
    System.out.println("请求参数：" + queryString);
    StringBuffer requestURL = request.getRequestURL();
    System.out.println("请求URL：" + requestURL); // 请求URL：http://localhost:8088/servlet_demo/request_demo01
    String remoteAddr = request.getRemoteAddr();
    System.out.println("请求IP地址：" + remoteAddr);
  }

  @Override
  protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
  }
}
