1. 新建项目： MyStruts2
2.导入相应的jar包：
3.修改web.xml文件：
<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>
小插曲：刚开始把filter写成了servlet,导致一直报错，后来才发现写错了，所以写的时候要细心
4.在src下新建：struts.xml文件，内容如下：
<?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>
<package name="helloworld" extends="struts-default">
<action name="product-input">
<result>/input.jsp</result>
</action>
</package>
</struts>
5.新建：index.jsp,主要代码如下：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<a href="product-input.action">product-input</a>
</body>
</html>
6.新建：input.jsp,主要代码如下：

<action name="product-save" class="com.xuzhiwen.action.Product" method="save">
<result name="save">/save.jsp</result>

13.新建类：com.xuzhiwen.action.Product ，内容如下：
package com.xuzhiwen.action;

public void setPassword(String password) {
this.password = password;
}
@Override
public String toString() {
return "Product [name=" + name + ", password=" + password + "]";
}
public String save(){
System.out.println("save()..."+this);
return "save";
}
}
14.添加save.jsp ,如下：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
