Struts逐步学习(1)-环境搭建

1. 首先要下载struts的jar包，地址http://struts.apache.org/

2. 解压Strusts包后，将lib文件夹里的jar包都加入到项目中WEB-INF下的lib文件夹下

3. 在解压后的webapps文件夹中解压struts-blank.war，将其中的struts-config.xml拷贝到项目中（避免手写出错，复制粘贴，做一些配置）

<?xml version="1.0" encoding="ISO-8859-1" ?><!DOCTYPE struts-config PUBLIC          "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"          "http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd"><struts-config><form-beans><form-bean name="loginForm" type="com.tgb.struts.LoginActionForm"></form-bean></form-beans><action-mappings><action path="/login"type="com.tgb.struts.LoginAction"name="loginForm"scope="request"><forward name="success" path="/login_success.jsp"></forward><forward name="error" path="/login_error.jsp"></forward></action></action-mappings></struts-config>

4. 配置web.xml部署ActionServlet。这个格式是相对固定的，按要求配置路径和类信息

<?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">  <display-name></display-name>  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list>      <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>2</param-value>    </init-param>    <init-param>      <param-name>detail</param-name>      <param-value>2</param-value>    </init-param>    <load-on-startup>2</load-on-startup>  </servlet>  <!-- Standard Action Servlet Mapping -->  <servlet-mapping>    <servlet-name>action</servlet-name>    <url-pattern>*.do</url-pattern>  </servlet-mapping></web-app>

5、新建一个LoginAction类，继承Action：

package com.tgb.struts;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.struts.action.Action;import org.apache.struts.action.ActionForm;import org.apache.struts.action.ActionForward;import org.apache.struts.action.ActionMapping;/** *  * 负责取得表单数据，调用业务逻辑，返回转向信息 * @author Jesse * */public class LoginAction extends Action {@Overridepublic ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception {LoginActionForm laf=(LoginActionForm)form;String username=laf.getUsername();String password=laf.getPassword();if("admin".equals(username)&& "admin".equals(password)){//登陆成功 return mapping.findForward("success");}else{//登录失败 return mapping.findForward("error");}}}

6、新建一个LoginActionForm类，继承ActionForm：

package com.tgb.struts;import org.apache.struts.action.ActionForm;/** * 登陆ActionForm，负责表单数收集数据 * @author Jesse * */@SuppressWarnings("serial")public class LoginActionForm extends ActionForm {private String username;private String password; public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}}

7、login.Jsp页面：

<%@ page language="java" contentType="text/html; charset=GB18030"    pageEncoding="GB18030"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=GB18030"><title>Insert title here</title></head><body><form action="login.do" method="post" >用户：<input type="text" name="username"><br>密码：<input type="password" name="password"><br><input type="submit" value="登陆"></form></body></html>

8、success.jsp ，error.jsp页面省略，只是一个显示界面。

至此，一个简单的Struts环境登陆实例就搭建起来啦。
