全自动化开发struts

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" );

}
