本文介绍如何使用Struts1.1搭建一个简单的登录示例项目，包括配置web.xml和struts-config.xml文件，创建JSP页面、Action类及ActionForm类，并展示运行效果。

在下载的struts1.1目录中有简单的例子struts-blank，拷贝其中jar, web.xml, struts-config.xml文件到自己的项目中并简单修改，就成了一个简单的struts1.1项目

工程的目录结构以及所需jar包：

1.web.xml中内容修改后如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>struts1_103</display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <display-name>Struts Blank Application</display-name>
  
  <!-- Standard Action Servlet Configuration (with debugging) -->
  <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>2</param-value>
    </init-param>
    <init-param>
      <param-name>detail</param-name>
      <param-value>2</param-value>
    </init-param>
    <load-on-startup>2</load-on-startup>
  </servlet>


  <!-- Standard Action Servlet Mapping -->
  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>


  <!-- The Usual Welcome File List -->
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
</web-app>

2.struts-config.xml中的内容修改后如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts-config PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN"
          "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

<struts-config>
    <form-beans>
        <form-bean
            name="userform"
            type="com.hsp.form.UserForm"/>
    </form-beans>

    <action-mappings>
        <action
            path="/login"
            type="com.hsp.action.LoginAction"
            name="userform"
            />
    </action-mappings>

</struts-config>

3.index.jsp的内容如下：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
  <html:form action="login">
     用户名:<html:text property="username" /><br/>
     密码：<html:text property="password" /><br/>
     <html:submit value="submit" />
  </html:form>

</body>
</html>

4.LoginAction 继承Action类

package com.hsp.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.hsp.form.UserForm;

public class LoginAction extends Action{
	
   @Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
		HttpServletRequest request, HttpServletResponse response)
		throws Exception {
	
	   UserForm userForm = (UserForm)form;
	   String username = userForm.getUsername();
	   String password = userForm.getPassword();
	   System.out.println("username :" + username);
	   System.out.println("username :" + password);
	return super.execute(mapping, form, request, response);
}
}

5.userForm 继承 ActionForm类

package com.hsp.form;

import org.apache.struts.action.ActionForm;

public class UserForm 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;
	}

}

6.发布项目后访问：http://localhost:8080/struts1_103/ 会进入index.jsp页面，如下：
