1、Strus里面写Action相关的东西主要是负责界面的跳转（过滤功能）。

在WEB-INFO的src的struts.xml文件中进行配置

<?xml version="1.0" encoding="GBK"?>
<!DOCTYPE struts PUBLIC

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

</interceptors>

<global-results>

<result name="login">/WEB-INF/content/login.jsp</result>
<result name="exception">/WEB-INF/content/error.jsp</result>

2、Servlet负责客户端和服务端的交互

复写service方法，service方法再通过请求方式进行分发。

3、H主要负责数据持久化操作

3.1对象与数据表对应

@Entity
@Table(name="auction_user")
public class AuctionUser
{
// 标识属性
@Id
@Column(name="user_id")
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer id;
// 用户名属性
private String username;
// 密码属性
private String userpass;
// 电子邮件属性
private String email;


// 根据属主关联的物品实体
@OneToMany(targetEntity=Item.class ,
mappedBy="owner")
private Set<Item> itemsByOwner = new HashSet<Item>();
// 根据赢取者关联的物品实体
@OneToMany(targetEntity=Item.class ,
mappedBy="winer")
private Set<Item> itemsByWiner = new HashSet<Item>();
// 该用户所参与的全部竞价
@OneToMany(targetEntity=Bid.class ,
mappedBy="bidUser")
private Set<Bid> bids = new HashSet<Bid>();


// 无参数的构造器
public AuctionUser()
{
}
// 初始化全部成员变量的构造器
public AuctionUser(Integer id , String username
, String userpass , String email)
{
this.id = id;
this.username = username;
this.userpass = userpass;
this.email = email;
}


// id的setter和getter方法
public void setId(Integer id)
{
this.id = id;
}
public Integer getId()
{
return this.id;
}


// username的setter和getter方法
public void setUsername(String username)
{
this.username = username;
}
public String getUsername()
{
return this.username;
}


// userpass的setter和getter方法
public void setUserpass(String userpass)
{
this.userpass = userpass;
}
public String getUserpass()
{
return this.userpass;
}


// email的setter和getter方法
public void setEmail(String email)
{
this.email = email;
}
public String getEmail()
{
return this.email;
}


// itemsByOwner的setter和getter方法
public void setItemsByOwner(Set<Item> itemsByOwner)
{
this.itemsByOwner = itemsByOwner;
}
public Set<Item> getItemsByOwner()
{
return this.itemsByOwner;
}


// itemsByWiner的setter和getter方法
public void setItemsByWiner(Set<Item> itemsByWiner)
{
this.itemsByWiner = itemsByWiner;
}
public Set<Item> getItemsByWiner()
{
return this.itemsByWiner;
}


// bids的setter和getter方法
public void setBids(Set<Bid> bids)
{
this.bids = bids;
}
public Set<Bid> getBids()
{
return this.bids;
}
}

public interface AuctionUserDao extends BaseDao<AuctionUser>
{
/**
* 根据用户名，密码查找用户
* @param username 查询所需的用户名
* @param pass 查询所需的密码
* @return 指定用户名、密码对应的用户
*/
AuctionUser findUserByNameAndPass(String username , String pass);
}

public class AuctionUserDaoHibernate
extends BaseDaoHibernate4<AuctionUser> implements AuctionUserDao
{


/**
* 根据用户名，密码查找用户
* @param username 查询所需的用户名
* @param pass 查询所需的密码
* @return 指定用户名、密码对应的用户
*/
public AuctionUser findUserByNameAndPass(String username , String pass)
{
// 执行HQL查询
List<AuctionUser> ul = (List<AuctionUser>)find(
"from AuctionUser au where au.username=?0 and au.userpass=?1" ,
username , pass);
// 返回查询得到的第一个AuctionUser对象
if (ul.size() == 1)
{
return (AuctionUser)ul.get(0);
}
return null;
}
}
