【複習】servlet之問號傳值（表單get請求傳值）

1，新建一個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;

@Override
public void init() throws ServletException {

    super.init();
}

@Override
protected 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"));

}


@Override
public 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>
  <!-- 主要在這裏配置 -->
  <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>

3，在瀏覽器輸入地址：
