首先建立一个web项目

引入需要的jar包

struts1二:基本环境搭建

建立包com.bjpowernode.struts
创建LoginAction

package com.bjpowernode.struts;

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;

public class LoginAction extends Action{

    @Override

    public ActionForward execute(ActionMapping mapping, ActionForm form,

            HttpServletRequest request, HttpServletResponse response)

            throws Exception {

        //struts1会自动的把相应的属性装载到对于的ActionForm中

        LoginActionForm laf = (LoginActionForm)form;

        if("admin".equals(laf.getUsername()) && "admin".equals(laf.getPassword())){

            return mapping.findForward("success");

        }

        return mapping.findForward("error");

    }

}

创建LoginActionForm

package com.bjpowernode.struts;

import org.apache.struts.action.ActionForm;

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;

    }

}

配置web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="3.0"

    xmlns="http://java.sun.com/xml/ns/javaee"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

  <display-name></display-name>

  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>

  <servlet>

      <servlet-name>struts1</servlet-name>

      <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>

  </servlet>

  <servlet-mapping>

      <servlet-name>struts1</servlet-name>

      <url-pattern>*.do</url-pattern>

  </servlet-mapping>

</web-app>

配置struts-config.xml,放置在WEB-INF下

<?xml version="1.0" encoding="ISO-8859-1" ?>

<!DOCTYPE struts-config PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"

"http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd">

<struts-config>

<form-beans>

<form-bean name="LoginActionForm" type="com.bjpowernode.struts.LoginActionForm"></form-bean>

</form-beans>

<action-mappings>

<action path="/login"

type="com.bjpowernode.struts.LoginAction"

name="LoginActionForm"

scope="request">

<forward name="success" path="/login_success.jsp"></forward>

<forward name="error" path="/login_error.jsp"></forward>

</action>

</action-mappings>

</struts-config>
