使用手动配置的方式开发第一个Struts项目的步骤以及实例

阅读更多

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

http://struts.apache.org/dtds/struts-config_1_3.dtd"> ;

  

  

      

      

      

  

  

    

      

      

      

      

          

          

          

      

      

  

 

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 >
