The first structs+spring+hibernate Web program

1. Database:

Column	Type	Comment
Id	Int (one) Auto Increment
Name	varchar (+) NULL
wr.	varchar (255) NULL

2. Overall structure:

3.model Layer Product.java

Package Com.zhoumo.model;

public class Product {
Private Integer ID;
private String name;
Private String URL;

constructor with no parameters
Public Product ()
{
}

Setter and getter methods for ID attributes
public void SetId (Integer ID)
{
This.id = ID;
}
Public Integer getId ()
{
return this.id;
}

Setter and Getter methods for the Name property
public void SetName (String name)
{
THIS.name = name;
}
Public String GetName ()
{
return this.name;
Setter and Getter methods for}//age properties
public void SetUrl (String URL)
{
This.url = URL;
}
Public String GETURL ()
{
return this.url;
}
}

4. Database mapping File Product.hbm.xml

<?xml version= "1.0" encoding= "GBK"?>
<! DOCTYPE hibernate-mapping Public
"-//hibernate/hibernate Mapping DTD 3.0//en"
"Http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd" >
<class name= "Product" table= "Product" >
<!--mapping Identity Properties--
<id name= "id" column= "id"
type= "int" >
<!--Specify the primary key generator policy--
<generator class= "Increment"/>
</id>
<!--Map Normal Properties--
<property name= "Name" type= "string"/>
<property name= "url" type= "string"/>
</class>

5.DAO Layer

Public interface Productdao {
/**
* Save Instance
* @param instances that need to be saved
* @return The IDENTITY property value of the instance you just saved
*/
Integer Save (product product);

}

6.DAO Implementation Layer

Package Com.zhoumo.dao.impl;
Import com.zhoumo.model.Product;
Import com.zhoumo.dao.*;
Import Org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public class Productdaoimpl extends Hibernatedaosupport implements Productdao {

/**
* Save Person instance
* @param person instance that person needs to save
* @return The IDENTITY property value of the person instance just saved
*/
Public Integer Save (product product)
{
Return (Integer) gethibernatetemplate ()
. Save (product);
}

7. Service Layer

Package com.zhoumo.service;

Import com.zhoumo.model.Product;

public interface productservice{
Integer Save (product product);
}

8. Service Implementation Layer

Package Com.zhoumo.service.impl;

Import Com.zhoumo.dao.ProductDao;
Import com.zhoumo.model.Product;
Import Com.zhoumo.service.ProductService;

public class Productserviceimpl implements productservice{

Private Productdao Productdao;
Relies on setter methods required to inject DAO components
public void Setproductdao (Productdao Productdao)
{
This.productdao = Productdao;
}
Public Integer Save (product product) {
TODO auto-generated Method Stub
return Productdao.save (product);
}

}

9. Action Layer

Package com.zhoumo.action;

Import com.opensymphony.xwork2.Action;
Import com.zhoumo.model.Product;
Import Com.zhoumo.service.ProductService;

public class Addproductaction implements Action
{
The following is a property for encapsulating user request parameters
Private product product;
Properties for encapsulating processing results
Private String tip;
Business logic components used by the system
Private Productservice Productservice;
Set setter methods necessary to inject business logic components
public void Setproductservice (Productservice productservice)
{
This.productservice = Productservice;
}

Setter and Getter methods for the person property
public void Setproduct (product product)
{
This.product = product;
}
Public Product getproduct ()
{
return this.product;
}

Setter and Getter methods for tip properties
public void Settip (String tip)
{
This.tip = tip;
}
Public String Gettip ()
{
return this.tip;
}
Public String Execute () throws Exception {
TODO auto-generated Method Stub
if (Productservice.save (product) >0)
{
Settip ("Haha, registered successfully!") ");
return SUCCESS;
}
Else
{
Settip ("Haha, registration failed! ");
return ERROR;
}

}
}
