Struts2.0框架源码实例,一个简单的用户登陆例子,要以直接使用

package com.sunny;

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport
	{
		private String username;

		private String password;

		public String getPassword()
		{
			return password;
		}

		public void setPassword(String password)
		{
			this.password = password;
		}

		public String getUsername()
		{
			return username;
		}

		public void setUsername(String username)
		{
			this.username = username;
		}

		public String execute() throws Exception
		{
			if("pan".equals(this.getUsername())&&"pan".equals(this.getPassword()))
				{
					return "success";
				}
			else
				{
					addFieldError("username","username or password is errors");
					return ActionSupport.INPUT;
				}
		}

		@Override
		public void validate()
		{
			if(null==this.getUsername()||"".equals(this.getUsername()))
				{
					addFieldError("username","username can not null");
				}
			if(null==this.getPassword()||"".equals(this.getPassword()))
				{
					addFieldError("password","password can not null");
