一 创建一个web工程

 

二 引入struts开发包

 

三 开发login.jsp文件

<%@  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 = "/strutstool2/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 开发action和actionForm

1、创建actionForm截图

 

创建完成后在struts-config.xml自动生成下面代码

   < form-beans  >

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

   form-beans >

在UserForm.java中自动生成下面代码

/*

* Generated by MyEclipse Struts

* Template path: templates/java/JavaClass.vtl

*/

package com.cakin.struts.form;

import org.apache.struts.action.ActionForm;

/**

* MyEclipse Struts

* Creation date: 10-02-2017

*

* XDoclet definition:

* @struts.form name="userForm"

*/

public class UserForm extends ActionForm {

    /*

     * Generated fields

     */

    /** username property */

    private String username;

    /** password property */

    private String password;

    /*

     * Generated Methods

     */

    /**

     * Returns the username.

     * @return String

     */

    public String getUsername() {

        return username;

    }

    /**

     * Set the username.

     * @param username The username to set

     */

    public void setUsername(String username) {

        this.username = username;

    }

    /**

     * Returns the password.

     * @return String

     */

    public String getPassword() {

        return password;

    }

    /**

     * Set the password.

     * @param password The password to set

     */

    public void setPassword(String password) {

        this.password = password;

    }

}

2、创建 action截图

 

创建完成后在struts-config.xml自动生成下面代码

   < action-mappings  >

     < action

       attribute = "userForm"

       name = "userForm"

       path = "/login"

       scope = "request"

       type = "com.cakin.struts.action.LoginAction"

       validate = "false"

       cancellable = "true"  />

 

   action-mappings >

创建完成后自动生成LoginAction

/*

* Generated by MyEclipse Struts

* Template path: templates/java/JavaClass.vtl

*/

package com.cakin.struts.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.struts.form.UserForm;

/**

* MyEclipse Struts

* Creation date: 10-02-2017

*

* XDoclet definition:

* @struts.action path="/login" name="userForm" scope="request"

*/

public class LoginAction extends Action {

    /*

     * Generated Methods

     */

    /**

     * Method execute

     * @param mapping

     * @param form

     * @param request

     * @param response

     * @return ActionForward

     */

    public ActionForward execute(ActionMapping mapping, ActionForm form,

            HttpServletRequest request, HttpServletResponse response) {

        UserForm userForm = (UserForm) form;// TODO Auto-generated method stub

        return null;

    }

}

 

五 编写ok.jsp和err.jsp

1 ok.jsp

<%@  page  language = "java"  import = "java.util.*"  import = "com.cakin.struts.form.*"  pageEncoding = "utf-8" %>

<%

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  <%= ((UserForm)request.getAttribute( "userForm" )).getUsername()  %>  < br >

   body >

html >

2 err.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 'err.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 >

    err < br >

   body >

html >

 

六 配置跳转关系

 

 

七 在atcion中添加业务逻辑

         public  ActionForward execute(ActionMapping mapping, ActionForm form,

                        HttpServletRequest request, HttpServletResponse response) {

                UserForm userForm = (UserForm) form; //  TODO  Auto-generated method stub

                

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

                         //把名字存放到request对象域

                         //request.setAttribute(" username ", userForm.getUsername());

                         return  mapping.findForward( "ok" );

                }

                 else {

                         return  mapping.findForward( "err" );

                }

        }
