struts2的登陆例子源码

STRUTS2做登陆的简单实现

 

第一步:创建一个WEB项目.

 

第二步:倒入STRUTS2的.jar包.

 

第三步:在src下创建一个struts.xml文件:

 

<struts>

- < package name =" myPackage " extends =" struts-default ">

- <!--

 login begin 

  -->

- < action name =" forwardLogin " method =" forward " class =" com.sinoest.login.action.LoginAction ">

  < result > /Login.jsp </ result >

  </ action >

- < action name =" login " class =" com.sinoest.login.action.LoginAction ">

  < result name =" input "> /Login.jsp </ result >

  < result > /Welcome.jsp </ result >

  </ action >

- <!--

 login end 

  -->

  </ package >

  </ struts >

第四步:配置web.xml文件:

<filter>
  <filter-name>struts2</filter-name>
  <filter-class>
   org.apache.struts2.dispatcher.FilterDispatcher
  </filter-class>
 </filter>
 <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>
 <jsp-config>
  <taglib>
   <taglib-uri>struts-tags</taglib-uri>
   <taglib-location>
    /WEB-INF/struts2－core－2.0.14.jar/struts-2.0.dtd
   </taglib-location>
  </taglib>
 </jsp-config>

第五步:写ACTION文件:

package com.sinoest.login.action;

 
import javax.servlet.http.HttpSession;

import com.opensymphony.xwork2.ActionSupport;
import org.apache.struts2.ServletActionContext;

 

public class LoginAction extends ActionSupport {

    /**
  *
  */
 private static final long serialVersionUID = 7315440691690047462L;

 private String name;

    private String password;

    public String getName() {

       return name;

    }

    public void setName(String name) {

       this.name = name;

    }

    public String getPassword() {

       return password;

    }

    public void setPassword(String password) {

       this.password = password;

    }

   

    public String forward() throws Exception {

       return SUCCESS;

    }

   

    @Override

    public String execute() throws Exception {

       if("admin".equals(name)) {

       HttpSession session = ServletActionContext.getRequest().getSession();

           session.setAttribute("name", name);

           return SUCCESS;

       } else {

           return INPUT;

       }

    }

}

第六步:创建/login.jsp和/welcome.jsp文件.
