Struts1.X入门

一、配置jar

    commons-beanutils-1.8.0.jar: 动态的获取/设值Java Bean的属性
    commons-digester-1.8.jar: 基于规则的XML文档解析,主要用于XML到Java对象的映射
    commons-fileupload-1.1.1.jar: struts中上传文件要用到
    commons-validator-1.3.1.jar: struts的验证框架
    commons-logging-1.0.4.jar:日志处理

    commons-chain-1.2.jar： 处理HTTP请求处理的基础机制
    struts-core-1.3.10.jar： struts的核心库

    struts-extras-1.3.10.jar： struts的扩展库
    oro-2.0.8.jar： 文本处理工具
    antlr-2.7.2.jar：语法分析器

二、配置web.xml

	<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>

 三、配置struts-config.xml

<?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="loginForm" type="com.tao.struts.form.LoginForm" />
		<form-bean name="loginResultForm" type="com.tao.struts.form.LoginResultForm" />
	</form-beans>

	<global-exceptions />
	<global-forwards />
	<action-mappings>
		<action attribute="loginForm" input="login.jsp" name="loginForm"
			path="/login" scope="request" type="com.tao.struts.action.LoginAction"
			cancellable="true">
			<forward name="success" path="/loginResult.do?method=success" />
			<forward name="failure" path="/loginResult.do?method=failure" />
		</action>
		<action attribute="loginResultForm" input="/login.do" name="loginResultForm"
			path="/loginResult" scope="request" type="com.tao.struts.action.LoginResultAction"
			cancellable="true" parameter="method">
		</action>

	</action-mappings>
	<message-resources parameter="ApplicationResources" />
</struts-config>

 四、Action和Form

package com.tao.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.tao.struts.form.LoginForm;

public class LoginAction extends Action {

	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) {
		LoginForm loginForm = (LoginForm) form;
		String forward = null;
		System.out.println("===========");
		System.out.println(loginForm.getUsername());
		System.out.println(loginForm.getPassword());
		if ("Tao".toLowerCase().equals(loginForm.getUsername().toLowerCase())
				&& "123".equals(loginForm.getPassword())) {
			forward = "success";
		} else {
			forward = "failure";
		}
		return mapping.findForward(forward);
	}
}

 

package com.tao.struts.form;

import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;

@SuppressWarnings("serial")
public class LoginForm extends ActionForm {
	private String username;

	private String password;

	public ActionErrors validate(ActionMapping mapping,
			HttpServletRequest request) {
		return null;
	}

	public void reset(ActionMapping mapping, HttpServletRequest request) {
	}

	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.tao.struts.action;

import java.io.IOException;
import java.io.PrintWriter;
import java.io.Writer;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.DispatchAction;

public class LoginResultAction extends DispatchAction {

	public ActionForward success(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws IOException {
		PrintWriter out = response.getWriter();
		out.print("success");
		return null;
	}

	public ActionForward failure(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws IOException {
		PrintWriter out = response.getWriter();
		out.print("failure");
		return null;
	}
}

 

package com.tao.struts.form;

import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;

@SuppressWarnings("serial")
public class LoginResultForm extends ActionForm {

	public ActionErrors validate(ActionMapping mapping,
			HttpServletRequest request) {
		return null;
	}

	public void reset(ActionMapping mapping, HttpServletRequest request) {

	}

}

 五、登录测试页

<%@ page language="java" pageEncoding="UTF-8"%>


<html>
	<head>
		<title>JSP for LoginForm form</title>
	</head>
	<body>
		<form action="${pageContext.request.contextPath }/login.do" method="post">
			用户名：
			<input name="username" type="text" />
			密码：
			<input name="password" type="password" />
			<input type="submit" value="登录" />
		</form>
	</body>
</html>
