快速搭建Struts1.x开发环境详细步骤与讲解

最近几天有空，想想好久没有搭建开发环境了，就尝试着去搭建一下，与此同时希望自己把它给写出来，方便自己以后查看同时也可以给一些初学者提供一些帮助和参考。

第一步：创建一个web Project：arrange_course

第二步：准备要用的基本jar包：

第三步：在WEB-INF 目录下创建如下几个文件（一般直接从其他项目中复制即可）

第四步：配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list>  <servlet> <servlet-name>img</servlet-name> <servlet-class>sun.zone.util.AuthImg</servlet-class> </servlet> <servlet-mapping> <servlet-name>img</servlet-name><url-pattern>/authImg</url-pattern> </servlet-mapping>  <servlet> <servlet-name>action</servlet-name> <servlet-class>org.apache.struts.action.ActionServlet</servlet-class> <init-param> <param-name>config</param-name> <param-value>/WEB-INF/struts-config.xml</param-value> </init-param> <init-param> <param-name>debug</param-name> <param-value>3</param-value> </init-param> <init-param> <param-name>detail</param-name> <param-value>3</param-value> </init-param> <load-on-startup>0</load-on-startup> </servlet> <servlet-mapping> <servlet-name>action</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping></web-app>

第五步：创建相关文件

登陆jsp页面 login.jsp

<%@ page language="java" pageEncoding="GB18030"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><title>森纵教育内部管理系统----登录界面</title><link href="css/bgcolor.css" mce_href="css/bgcolor.css" rel="stylesheet" type="text/css"><mce:script src="js/login_check.js" mce_src="js/login_check.js"></mce:script><mce:style type="text/css"></mce:style><style type="text/css" mce_bogus="1">body {background-image: url("image/login_bg.jpg");}</style></head><SCRIPT language=javascript>function refresh(){document.getElementById("authImg").src='authImg?now='+ new Date();}</script><body vlink="red"><p> </p><p align="center"><% String validateerror=(String)request.getAttribute("validateerror"); String error=(String)request.getAttribute("error"); if(validateerror!=null){ %><font color="red" class="STYLE11">验证码错误,请重新输入!!!</font><%}else if(error!=null){ %><font color="red" class="STYLE11">你输入的用户名或密码有误,请重新输入!!!</font><%} %></p><form name="loginform" action="login.do" method="post"><table width="330" height="125" border="1" align="center" background="image/admin_bg_1.jpg"><tr><td><div align="center" class="STYLE15">登录</div></td></tr><tr><td><span class="STYLE11"> <label><div align="center"><span class="STYLE2"> <input name="radiobutton" type="radio" value="manager" checked> 管理员<input name="radiobutton" type="radio" value="teacher"> 教师 </span></div></label> </span></td></tr><tr><td><span class="STYLE9"> 用户名: <inputname="username" type="text"> *</span></td></tr><tr><td><span class="STYLE9"> 密码: <input name="upassword" type="password"> *</span></td></tr><tr><td><span class="STYLE9"> 验证码:</span><span class="STYLE11"> <input name="validate" type="text"size="6" maxlength="6"> <img src="authImg" mce_src="authImg" id="authImg" /><ahref="#" onClick="refresh()">换一张</a></span></td></tr><tr><td><div align="center"><input type="submit" value="提交" width="59" height="20" onClick="login_checkForm()" /></div></td></tr></table></form></body></html>

处理登陆请求ACTION，LoginAction.java

public class LoginAction extends Action {@Overridepublic ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception {System.out.println("我进入这里面来了");return mapping.findForward("login_success");}}

本例中的验证码处理类AuthImg.java

package sun.zone.util;import javax.servlet.*;import javax.servlet.http.*;import java.io.*;import java.awt.*;import java.awt.image.*;import java.util.*;import javax.imageio.*; @SuppressWarnings("serial")public class AuthImg extends HttpServlet{ private Font mFont = new Font("Arial Black", Font.PLAIN, 16); public void init() throws ServletException { super.init(); } Color getRandColor(int fc,int bc) { Random random = new Random(); if(fc>255) fc=255; if(bc>255) bc=255; int r=fc+random.nextInt(bc-fc); int g=fc+random.nextInt(bc-fc); int b=fc+random.nextInt(bc-fc); return new Color(r,g,b); } public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setHeader("Pragma","No-cache"); response.setHeader("Cache-Control","no-cache"); response.setDateHeader("Expires", 0); response.setContentType("image/jpeg"); int width=100, height=18; BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); Graphics g = image.getGraphics(); Random random = new Random(); g.setColor(getRandColor(200,250)); g.fillRect(1, 1, width-1, height-1); g.setColor(new Color(102,102,102)); g.drawRect(0, 0, width-1, height-1); g.setFont(mFont); g.setColor(getRandColor(160,200)); for (int i=0;i<155;i++) { int x = random.nextInt(width - 1); int y = random.nextInt(height - 1); int xl = random.nextInt(6) + 1; int yl = random.nextInt(12) + 1; g.drawLine(x,y,x + xl,y + yl); } for (int i = 0;i < 70;i++) { int x = random.nextInt(width - 1); int y = random.nextInt(height - 1); int xl = random.nextInt(12) + 1; int yl = random.nextInt(6) + 1; g.drawLine(x,y,x - xl,y - yl); } String sRand=""; for (int i=0;i<6;i++) {String tmp = getRandomChar(); sRand += tmp; g.setColor(new Color(20+random.nextInt(110),20+random.nextInt(110),20+random.nextInt(110))); g.drawString(tmp,15*i+10,15); } HttpSession session = request.getSession(true); session.setAttribute("rand",sRand); g.dispose(); ImageIO.write(image, "JPEG", response.getOutputStream()); } private String getRandomChar() {int rand = (int)Math.round(Math.random() * 2);long itmp = 0;char ctmp = '/u0000';switch (rand){case 1:itmp = Math.round(Math.random() * 25 + 65);ctmp = (char)itmp;return String.valueOf(ctmp);case 2:itmp = Math.round(Math.random() * 25 + 97);ctmp = (char)itmp;return String.valueOf(ctmp);default :itmp = Math.round(Math.random() * 9);return String.valueOf(itmp);} }}

第六步：配置文件struts-config.xml实现页面和处理类Action之间的联系

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd"><struts-config><form-beans></form-beans><action-mappings><action path="/login" type="sun.zone.action.LoginAction"input="/login.jsp"><forward name="login_success" path="/loginpage/login_sucess.jsp" /><forward name="teacher_login_success" path="/WEB-INF/teacher_login_index.jsp" /></action></action-mappings></struts-config>

至此，Struts1.2开发环境搭建完成，后待续。
