struts标签学习（低版本）

为了便于理解和记忆整个过程，将学过的东西贴过来。项目整体结构：

java代码如下：

ActionForm负责对数据的包装。

Code:

/*
* Generated by MyEclipse Struts
* Template path: templates/java/JavaClass.vtl
*/
package prj30.form;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
/**
* MyEclipse Struts
* Creation date: 01-26-2010
*
* XDoclet definition:
* @struts.form name="regForm"
*/
public class RegForm extends ActionForm {
private String account;
private String password;
private String info;
private String hiddenInfo;
private String sex="girl";//可以通过ActionForm来设置表单的初始值。
private String home;
private String[] fav={"sing"};//可以用数组属性来存储传过来的多个同名表单元素。
private boolean interm;
private String[] books={"struts","hibernate"};
public String[] getBooks() {
return books;
}
public void setBooks(String[] books) {
this.books = books;
}
public boolean isInterm() {
return interm;
}
public void setInterm(boolean interm) {
this.interm = interm;
}
public String[] getFav() {
return fav;
}
public void setFav(String[] fav) {
this.fav = fav;
}
public String getHome() {
return home;
}
public void setHome(String home) {
this.home = home;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getHiddenInfo() {
return hiddenInfo;
}
public void setHiddenInfo(String hiddenInfo) {
this.hiddenInfo = hiddenInfo;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getInfo() {
return info;
}
public void setInfo(String info) {
this.info = info;
}
public String getAccount() {
return account;
}
public void setAccount(String account) {
this.account = account;
}
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
return null;
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
//该函数是每次提交时都会调用的重新设置interm的值
this.interm=false;
}
}

Action负责对数据的处理和jsp界面的跳转：

Code:

/*
* Generated by MyEclipse Struts
* Template path: templates/java/JavaClass.vtl
*/
package prj30.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 prj30.form.RegForm;
public class RegAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
RegForm regForm = (RegForm) form;// TODO Auto-generated method stub
request.setAttribute("regForm", regForm);
return new ActionForward("/regResult.jsp");
}
}

哎，郁闷怎么没有jsp的代码格式呢！

为了对struts标签的学习，故写了一个注册表单界面和一个注册结果的界面。

Code:

<%@ page language="java" pageEncoding="gb2312"%>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
<html>
<head>
<title>JSP for RegForm form</title>
</head>
<body>
<html:form action="/reg" method="post">
请您输入账号(文本框)：<html:text property="account"></html:text>
请输入您的密码(密码框):<html:password property="password" ></html:password>
<!-- 注意：在Struts标签中，系统看到某个property，如果没有手动设置value，
就是调用个ActionFrom的get方法来设置初始值 -->
请输入您的个人信息(多行文本框):
<html:textarea property="info" rows="6" cols="40"></html:textarea>
<html:hidden property="hiddenInfo" value="welcome 爱你一万年"></html:hidden>
请选择性别(单选按钮)：<html:radio property="sex" value="boy"></html:radio>男
<html:radio property="sex" value="girl"></html:radio>女
籍贯(下拉菜单):<html:select property="home" value="lfjieshi">
<html:option value="lfjieshi">陆丰碣石</html:option>
<html:option value="lfdonghai">陆丰东海</html:option>
<html:option value="lfjiazi">陆丰甲子</html:option>
</html:select>
爱好（多项复选框）：
<html:multibox property="fav" value="sing"></html:multibox>唱歌
<html:multibox property="fav" value="swim"></html:multibox>游泳
<html:multibox property="fav" value="playgame"></html:multibox>
<html:multibox property="fav" value="dance">跳舞</html:multibox>
是否会员（单选复选框）：
<html:checkbox property="interm"></html:checkbox>
选择您喜欢的书本(多选下拉类表框):
<html:select property="books" multiple="true" size="6">
<html:option value="database">数据库</html:option>
<html:option value="struts">struts框架</html:option>
<html:option value="spring">spring框架</html:option>
<html:option value="hibernate">hibernate框架</html:option>
</html:select>
<html:submit value="提交注册信息"></html:submit>
</html:form>
</body>
</html>

Code:

<%@ page language="java" pageEncoding="gb2312"%>
<%@page import="prj30.form.RegForm"%>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
<html>
<head>
<title>注册处理结果界面</title>
</head>
<body>
<%RegForm regForm=(RegForm)request.getAttribute("regForm"); %>
账号：<%=regForm.getAccount() %>
密码：<%=regForm.getPassword() %>
个人信息：<%=regForm.getInfo() %>
隐藏的表单is:<%=regForm.getHiddenInfo() %>
性别：<%=regForm.getSex() %>
籍贯：<%=regForm.getHome() %>
爱好：<%
String[] fav=regForm.getFav();
for(int i=0;i<fav.length;i++){
out.println(fav[i]);
}
%>
是否会员：<%=regForm.isInterm() %>
选择的书本是：<%
String[] books=regForm.getBooks();
for(int i=0;i<books.length;i++){
out.println(books[i]);
}%>
</body>
</html>

配置文件是直接使用图形界面操作的，代码贴下来有空也可以研究研究

Code:

<?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="regForm" type="prj30.form.RegForm" />
</form-beans>
<global-exceptions />
<global-forwards />
<action-mappings >
<!-- attribute="regForm"
input="/reg.jsp" scope="request" -->
<action
name="regForm"
path="/reg"
type="prj30.action.RegAction" />
</action-mappings>
<message-resources parameter="prj30.ApplicationResources" />
</struts-config>

暂时搁浅！
