第一个Struts2的实例:
本实例的开发工具及语言:eclipse 3.2 + struts2 + tomcat 5.5
实现用户登陆功能,在这因没有连接数据库,所以用固定的用户名和密码登陆.
用户名:luanmad
密码:admin
本实例用到的文件及其结构:(看图1)

//***********************************************************************
1.Tomcat 5.5的具体配置在这里就赘述了,可以上网搜(一大把的)
本实例配置用到的TOMCAT 5.5 文件是server.xml.
在你安装好的TOMCAT 5.5目录下找到conf的文件夹,下面有一个叫server.xml的文件(如:C:/tomcat 5.5/conf/server.xml),打开此文件进行编辑,在<Host>和</Host>之间加入一句:
<Context path="/MyFirstStruts2" docBase="K:/EclipsWorks/MyFirstStruts2/WebRoot" debug="0" reloadable="true" crossContext="true">
</Context>
此句是用于让TOMCAT 5.5 找到你的启动程序;
2.编写LoginAction.java 文件,用于处理登陆的作息,在(MyFirstStruts2/src/cn/struts2/LoginAction.java)
LoginAction.java
//***********************************************************************
package cn.struts2;
import com.opensymphony.xwork2.ActionSupport;
public class LoginAction extends ActionSupport
{
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
{
String path=null;
if(name.equals("luanmad") && password.equals("admin"))
{
path = SUCCESS;
}
else
{
path = ERROR;
}
return path;
}
//重写一个validate()函数,它用来对用户输入信息的验证,它先于execute()函数执行
@Override
public void validate()
{
// 验证用户名和密码是否为空
if(null == name || "".equals(name))
{
this.addFieldError("name", "name is required!");
}
if(null == password || "".equals(password))
{
this.addFieldError("password", "password is required!");
}
}
}
//***********************************************************************
3.配置struts.xml文件(src/struts.xml)
struts.xml
//***********************************************************************
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd">

<package name="struts2" extends="struts-default">
<action name="login" class="cn.struts2.LoginAction">
<result name="success">/loginSuccess.jsp</result>
<result name="error">/loginFailure.jsp</result>
<result name="input">/login.jsp</result>
</action>
</package>
</struts>
//***********************************************************************
4.配置web.xml文件(WebRoot/WEB-INF/web.xml)
web.xml
//***********************************************************************

6.注意别忘了导入STRUTS2的JAR包(用此5个即可)(放在WebRoot/WEB-INF/lib/)下,这是必须的.
commons-logging-1.0.4.jar
freemarker-2.3.8.jar
ognl-2.6.11.jar
struts2-core-2.0.11.2.jar
xwork-2.0.5.jar
7.如图1
同时也要就以上5个JAR包导入Referced Libraries里,这是在ECLIPSE 下编辑时用的.
8.此程序可以正常运行,当你配置好时在浏览器上写 http://localhost:8080/MyFirstStruts2/login.jsp 即可(默认是8080端口)
