【复习】servlet之问号传值（表单get请求传值）

1，新建一个servlet：
package com.servlet;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class ServletFormGet extends HttpServlet{
/**
*
*/
private static final long serialVersionUID = 1L;

@Overridepublic void init() throws ServletException {    super.init();}@Overrideprotected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {    response.setContentType("text/html");    PrintWriter out=response.getWriter();    out.println("use from get method read data:"+"welcome"+request.getParameter("name"));}@Overridepublic void destroy() {    super.destroy();}

}

2，配置web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">  <display-name>servlet_02_fromGet</display-name>  <welcome-file-list>    <welcome-file>index.html</welcome-file>    <welcome-file>index.htm</welcome-file>    <welcome-file>index.jsp</welcome-file>    <welcome-file>default.html</welcome-file>    <welcome-file>default.htm</welcome-file>    <welcome-file>default.jsp</welcome-file>  </welcome-file-list>  <!-- 主要在这里配置 -->  <servlet>    <servlet-name>fromget</servlet-name>    <servlet-class>com.servlet.ServletFormGet</servlet-class>  </servlet>  <servlet-mapping>    <servlet-name>fromget</servlet-name>    <url-pattern>/ServletFormGet</url-pattern>  </servlet-mapping></web-app>
