JAVAWEB 一一 userweb1（原生，非servlet版，用doXXX.jsp代替servlet）

创建数据库和表

首先，创建一个web项目

然后引入jar包

创建jsp页面

创建包

创建接口

实现类

详细内容

首先创建一个登陆页面 login.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">

    <title>My JSP ‘Login.jsp‘ starting page</title>

    <meta http-equiv="pragma" content="no-cache">
    <meta http-equiv="cache-control" content="no-cache">
    <meta http-equiv="expires" content="0">
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="This is my page">
    <!--
    <link rel="stylesheet" type="text/css" href="styles.css">
    -->

  </head>

  <body>
    <form action="jsp/dologin.jsp" method="post">
        用户名:<input type="text" name="username"/><br/>
        密码 :<input type="password" name="password"/> <br/>
        <input type="submit" value="登录"/>    
        <input type="reset" value="重置"/>
       </form>
  </body>
</html>

　　

创建要跳转的页面 (充当半个控制器servlet)  dologin.jsp

User

entity层

实体类

User.java

也可以直接跳转到别的页面比如list.jsp 一个雇员信息列表的页面 但是  这个页面的数据是从数据库查出来的(这样才是动态页面啊)


那么就需要再做一遍上面的步骤  （创建Emp接口和实现类 还有dolist页面 list页面）

dolist.jsp

所以 我们需要跳转到一个dolist页面 (充当servlet)让他把页面从数据来出来后跳转到list页面

查以上就是一个查( public List<Emp> getEmpList() )的步骤


那么 增删改 也一样 都是一个更新操作（dao.executeUpdate(sql, obj);）


不同之处在于 增删改 都是对数据库进行了修改（dao.executeUpdate(sql, obj);）


然后执行查的操作 最终跳转到dolist.jsp →list.jsp 页面


在list展示页面 a标签对应的一个添加雇员的页面

JAVAWEB 一一 userweb1（原生，非servlet版，用doXXX.jsp代替servlet）的相关文章


						

		

			

                Servlet是什么？JSP和Servlet的区别。Servlet的生命周期。
			

		

		

									

				Servlet(Server Applet),全称Java Servlet, 是用Java编写的服务器端程序.而这些Sevlet都要实现Servlet这个借口.其主要功能在于交互式地浏览和修改数据,生成动态Web内容.Servlet运行于支持Java的应用服务器中. HttpServlet 重写doGet和doPost方法或者你也可以重写service方法完成对get和post请求的响应. 2.JSP和Servlet的区别 JSP经编译后就变成了“类servlet”. JSP由HTML代码和JS			

		

	

						

		

			

                JSP和servlet有什么区别?
			

		

		

									

				JSP和servlet有什么区别? JSP是Servlet技术的扩展,本质上是Servlet的简易方式,更强调应用的外表表达. JSP编译后是"类servlet". Servlet和JSP最主要的不同点: 1.  Servlet的应用逻辑是在Java文件中,并且完全从表示层中的HTML里分离开来. 2. JSP的情况是Java和HTML可以组合成一个扩展名为.jsp的文件. 3. JSP侧重于视图,Servlet主要用于控制逻辑			

		

	

				

		

			

                jsp和servlet的联系与区别
			

		

		

									

				刚开始接触jsp和servlet的时候,觉得这两个完全没什么联系,还是太天真 jsp实际上就是servlet,可以说jsp和servlet是同一种东西,只是不同的表现形式罢了. tomcat会将jsp最终转化成一个servlet,我们可以去tomcat下work目录下看出一点端倪,如下图: 发现index.jsp最终转化成了一个java文件.所以实际上jsp和servlet就是同一个东西,只是不同的表现形式. 客户端访问,都是请求的服务器,没有跟servlet打交道,tomcat服务器然后组装请			

		

	

				

		

			

                【转】jsp 和 servlet的联系和区别
			

		

		

									

				简单的说,SUN首先发展出SERVLET,其功能比较强劲,体系设计也很先进,只是,它输出HTML语句还是采用了老的CGI方式,是一句一句输出,所以,编写和修改HTML非常不方便. 后来SUN推出了类似于ASP的镶嵌型的JSP,把JSP TAG镶嵌到HTML语句中,这样,就大大简化和方便了网页的设计和修改.新型的网络语言如ASP,PHP,JSP都是镶嵌型的SCRIPT语言. JSP在本质上就是SERVLET,但是两者的创建方式不一样. Servlet完全是JAVA程序代码构成,擅长于流程控制和事务

				2015.11.26购物车,非cookie版 [点击来,你发现被骗了(笑哭,笑哭,笑哭,源代码的话,留下邮箱吧,是在不好找这一时半会儿的.)] Jsp通过反射机制获取bean中的标签,但其实,可以没有真实的属性与之对应.只要是符合getset方法设置的名字,就可以通过el表达式在jsp页面中获取. 更新核心代码: private void update(HttpServletRequest request, HttpServletResponse response) throws Servlet			

		

	

				

		

			

                POJ 1780 Code (欧拉回路+非递归版dfs)
			

		

		

									

				题目地址:POJ 1780 还是求序列的欧拉回路.只不过这题有两坑. 第一坑是用数字来当点的话,会MLE,因为每个数字可以连10条边,100w条边会MLE,即使用vector也会TLE.这题可以用边来记录,对于n为1时直接输出,然后后面的,比如12,23这两个点就用边权值为123来表示这两个点,这样就把点和边的范围都缩小了10倍. 第二坑是用递归的dfs会爆栈,亲测即使加手扩栈也会爆..(简直丧心病狂..)需要用非递归版dfs,也不难,dfs本身就是利用的栈,所以改成栈的形式就可以了. 代码如下
