struts1二:基本环境搭建

首先建立一个web项目

引入需要的jar包

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>
