一。在WEB-INF下建立一个lib文件夹然后将包拷贝进来

二。配置web-xml文件配置过滤器filter

<filter>

<filter-name>struts2</filter-name>

<filter-class>

     org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

</filter-class>

</filter>

<filter-mapping>

<filter-name>struts2</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

三。创建login.jsp及success.jsp

login.jsp

<form action="login.action" method="post">

       姓名：<input type="text" name="name" value="丽丽"> <br>

       密码：<input type="password" name="password" value="123123"> <br>

            <input type="submit" value="提交">

</form>

success.jsp

<body>

<h2>用户登录成功</h2>

账号：${name}<br>

密码：${password}<br>

</body>

四。创建LoginAaction.java类继承于ActionSupport 并重写execute()方法

public class LoginAction extends ActionSupport {

   private String name;

   private String password;

   @Override

   public String execute() throws Exception {

       System.out.println("账号" + name);

       System.out.println("密码" + password);



       return "success";

   }

   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;

   }

}

五。配置struts.xml并拷贝到src目录下

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

<!DOCTYPE struts PUBLIC

   "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

   "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

       

        <constant name="struts.enable.DynamicMethodInvocation" value="false" />

        

        <constant name="struts.devMode" value="true" />



        <package name="default" namespace="/" extends="struts-default">







           <action name="login" class="com.learn.action.LoginAction">

           <result name="success">

           /success.jsp

           </result>

           </action>

        </package>



</struts>
