1、簡介

struts是WEB程序MVC分層架構(gòu)中的C，屬于控制層，主要進(jìn)行處理用戶的請求，基于請求驅(qū)動。獲取用戶的請求地址并將表單中的數(shù)據(jù)封裝到Form對象后交給Action進(jìn)行處理。在Action中進(jìn)行條用業(yè)務(wù)層處理具體的請求后將結(jié)果通過ActionMapping封裝跳轉(zhuǎn)地址返回給用戶。struts是對servlet的再次封裝，使得更加靈活高效。下面以一個登錄的實例講解struts的開發(fā)過程。

2、在新建的web工程中添加以下struts1.x jar包

antlr-2.7.6.jar、commons-beanutils.jar、commons-digester.jar、commons-fileupload.jar、commons-logging-1.0.4.jar、commons-validator.jar、jakarta-oro.jar、struts.jar。

3、web.xml進(jìn)行如下配置

[html] view plain copy print ?

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www./2001/XMLSchema-instance" xmlns="http://java./xml/ns/javaee" xmlns:web="http://java./xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java./xml/ns/javaee http://java./xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>MyStruts1Prj</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/conf/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>

4、新建登陸頁面login.jsp

[html] view plain copy print ?

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www./TR/html4/loose.dtd">
<html>
<head>
<%
String basePath = request.getContextPath();
%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>登陸頁面</title>
</head>
<body>
<h1>登陸頁面</h1>
<hr>
<form action="<%=basePath %>/login.do" method="post" >
userName:<input id="userName" name="userName" type="text" /><br>
passWord:<input id="passWord" name="passWord" type="password" /><br>
<input type="submit" id="submit" name="submit" value="submit" />
</form>
</body>
</html>

5、新建登陸成功后的跳轉(zhuǎn)頁面loginSucces.jsp

[html] view plain copy print ?

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www./TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>登陸成功頁面</title>
</head>
<body>
<h1>歡迎[<%=request.getAttribute("userName") %>]登陸成功！</h1>
</body>
</html>

6、新建登陸失敗后的跳轉(zhuǎn)頁面loginError.jsp

[html] view plain copy print ?

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www./TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>登陸失敗頁面</title>
</head>
<body>
<h1>登陸失??！</h1>
</body>
</html>

7、新建LoginActionForm.java

[java] view plain copy print ?

package com.lanp.webapp.form;
import org.apache.struts.action.ActionForm;
/**
* 封裝登陸表單數(shù)據(jù)的FORM類
* @author LanP
* @since 2012年4月11日23:07:09
* @version v1.0
*/
@SuppressWarnings("serial")
public class LoginActionForm extends ActionForm {
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;
}
}

8、新建LoginAction.java

[java] view plain copy print ?

package com.lanp.webapp.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.lanp.webapp.form.LoginActionForm;
/**
* 處理登陸的Action類
* @author LanP
* @since 2012年4月11日23:07:09
* @version v1.0
*/
public class LoginAction extends Action {
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
String path = "error";
LoginActionForm loginActionForm = (LoginActionForm)form;
String userName = loginActionForm.getUserName();
String passWord = loginActionForm.getPassWord();
if(null != userName && "admin".equals(userName) && null != passWord && "admin".equals(passWord)) {
path = "success";
request.setAttribute("userName", userName);
} else {
path = "error";
}
return mapping.findForward(path);
}
}

9、配置struts-config.xml

[html] view plain copy print ?

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts./dtds/struts-config_1_2.dtd">
<struts-config>
<form-beans>
<form-bean name="loginActionForm" type="com.lanp.webapp.form.LoginActionForm">
</form-bean>
</form-beans>
<action-mappings>
<action path="/login"
type="com.lanp.webapp.action.LoginAction"
name="loginActionForm"
scope="request">
<forward name="success" path="/jsp/loginSucces.jsp" />
<forward name="error" path="/jsp/loginError.jsp" />
</action>
</action-mappings>
</struts-config>

OK，TKS！
