使用手动配置的方式开发第一个Struts项目的步骤以及实例

一先创建一个web工程

二引入struts的开发包到项目

从 http://struts.apache.org 下载

三编写login.jsp

<%@ page language = "java" import = "java.util.*" pageEncoding = "ISO-8859-1" %>

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" >

<!--

-->

</ head >

< body >

< form action = "/strutslogin/login.do" method = "post" >

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

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

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

</ form >

</ body >

</ html >

四编写ActonForm（用户表单）和Action（登录小队长）

package com.cakin.forms;

//这是一个用户表单，用于填充数据的

import org.apache.struts.action.ActionForm;

public class UserForm extends ActionForm {

//定义属性【属性名应该和 jsp 页面的控件名称一致】

//如果有人提出疑问：表单名字是不是一定要和控件名称一样？不一定，但要保证get和set方法的名字和

//控件名称一致

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;

}

package com.cakin.actions;

//这是一个action（表示小队长，需要继承Action）

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;

import com.cakin.forms.UserForm;

public class LoginAction extends Action {

//我们需要重新编写一个方法：execute会被自动调用，有点类似 servlet 的service方法。

@Override

public ActionForward execute(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response)

throws Exception {

//把form转成对应的UserForm对象

UserForm userForm=(UserForm)form;

//简单验证

if ( "123" .equals(userForm.getPassword())){

return mapping.findForward( "ok" );

}

else {

return mapping.findForward( "err" );

}

五编写struts-config.xml文件，该文件用于配置action actionForm以及对应关系，跳转位置，一般放在/WEB-INF目录下

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN" " http://struts.apache.org/dtds/struts-config_1_3.dtd"> ;

<struts-config>

<form-beans>

<form-bean name="userForm" type="com.cakin.forms.UserForm"></form-bean>

</form-beans>

<action-mappings>

</action>

</action-mappings>

</struts-config>

六写出welcome.jsp页面

<%@ page language = "java" import = "java.util.*" pageEncoding = "ISO-8859-1" %>

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 'wel.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" >

<!--

-->

</ head >

< body >

welcome < br >

</ body >

</ html >

七配置web.xml中的ActionServlet

<? xml version = "1.0" encoding = "UTF-8" ?>

< web-app xmlns = " http://java.sun.com/xml/ns/javaee" ; xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance" ; version = "2.5" xsi:schemaLocation = " http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" ; >

< display-name />

< 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 >

< welcome-file-list >

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

</ welcome-file-list >

</ web-app >
