jsp发布源码_jsp源代码

JSP 上传下载代码

       æˆ‘给你把，

       1.首先下这两个包commons-fileupload-1.2.1.jar，commons-io-1.3.2.jar

       2.编写前台页面

       <%@ page language="java" pageEncoding="gbk"%>

       <%@ taglib uri="/struts-tags" prefix="s" %>

       <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4. Transitional//EN">

       <html>

        <body>

        <form action="<%=request.getContextPath()%>/UploadServlet" method="post" enctype="multipart/form-data">

        username:<input type="text" name="username"><br>

        password:<input type="password" name="password"><br>

        file:<input type="file" name="file"><br>

        <input type="submit" value="submit"><br>

        </form>

        </body>

       </html>

       3.编写servlet

       package cn.jci.upload.servlet;

       import java.io.File;

       import java.io.FileOutputStream;

       import java.io.IOException;

       import java.io.InputStream;

       import java.io.OutputStream;

       import java.util.List;

       import javax.servlet.ServletException;

       import javax.servlet..jci.upload.servlet.UploadServlet</servlet-class>

        </servlet>

        <servlet-mapping>

        <servlet-name>UploadServlet</servlet-name>

        <url-pattern>/UploadServlet</url-pattern>

        </servlet-mapping>

        <welcome-file-list>

        <welcome-file>index.jsp</welcome-file>

        </welcome-file-list>

       </web-app>

       5.发布

       ok了

       è¿™æ˜¯æœ€åŽŸå§‹çš„上传文件的办法，现在struts2上传的话，就要轻松好多

求jsp登录源码 急急急急急急急急急急急

       登陆页面 index.jsp源码：

jsp的执行过程是怎样的

       Web容器处理JSP文件的执行过程包括以下4个部分：

       1、 客户端发出Request请求；

       2、码j码黑盒商城源码支持个人免签 收到请求后，源代机战私服源码JSPContainer将JSP转译成Servlet的布源pubg源码分享源代码；

       3、Web容器将产生的码j码seo监测源码Servlet源代码经过编译后，并加载到内存执行；

       4、源代autojs源码解密把结果响应至客户端。布源
