Struts2 开发步骤。  
第一步：导入相关struts2的jar包  
![jar包][jar]

第二步：在web.xml 添加过滤器来注册struts2

<filter>
          <filter-name>struts2</filter-name>
          <filter-class>
              org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
          </filter-class>
      </filter>
      <filter-mapping>
      <filter-name>struts2</filter-name>
      <url-pattern>/*</url-pattern>
      </filter-mapping>

第三步：创建Action，继承com.opensymphony.xwork2.ActionSupport。

package com.dx.action;
    import com.opensymphony.xwork2.ActionSupport;
    public class LoginAction extends ActionSupport{ 
    private static final long serialVersionUID = 1L;
    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 execute()throws Exception{
    return "success";
    }
    }

第四步：创建struts.xml文件配置action

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN" "http://struts.apache.org/dtds/struts-2.5.dtd">
    <struts>   
        <package name="default" extends="struts-default">
            <action name="login" class="com.dx.action.LoginAction">
                <result name="success">success.jsp</result>
            </action>
        </package> 
    </struts>

第五步：启动服务器。
