1. First implement an interface.
============================================================
Package Com.cqtele.tnbos;import java.util.*;p ublic interface Iuserdao {public void Insertuser (userInfo user); public Lis T Finduser (String SQL);
==============================================================
2. Implement this interface.
This simplifies the processing of Hibernate sessions using Spring's Aop-driven hibernatetemplate.
================================================================package Com.cqtele.tnbos;import java.util.*;
Import Net.sf.hibernate.*;import Net.sf.hibernate.cfg.*;import Java.io.serializable;import org.springframework.orm.hibernate.*;//. Hibernatecallback;import Org.springframework.orm.hibernate.support.HibernateDaoSupport;
public class Userdao extends Hibernatedaosupport implements iuserdao{//public List name=null; List List=null; public void Insertuser (UserInfo user) {gethibernatetemplate (). saveorupdate (user);} public List Finduser (String sql) { Return Gethibernatetemplate (). find (SQL); }}
=================================================================
3. Declarative management transactions.
Bean.xml
==========================================================================
<?xml version= "1.0" encoding= "UTF-8"?> <! DOCTYPE beans Public "-//spring/dtd bean/en" "Http://www.springframework.org/dtd/spring-beans.dtd" >

4. Use. (This is an example of a shopping cart.) ==============================================================================
Package Com.cqtele.tnbos;
Import Java.util.*;import Java.io.*;import Org.springframework.beans.factory.beanfactory;import Org.springframework.beans.factory.xml.xmlbeanfactory;import Org.aopalliance.aop.Advice;
public class login{Private List list=null, private String sql= "from UserInfo"; Public List getallmessagelist () {try{InputStream is = new FileInputStream ("Bean.xml"); Xmlbeanfactory factory = new Xmlbeanfactory (IS); Iuserdao user = (Iuserdao) factory.getbean ("Daoproxy"); List = User.finduser (SQL); }catch (IOException IoE) {System.out.println ("Getallmessagelist Ocurr error!! Message: "+ioe.getmessage ()); } return list; }}
======================================================================
5. Summary
======================================================================
Hibernate is an advanced OR mapping tool, and Spring is an AOP framework and an IOC container. The combination of these two technologies allows developers to write code comparable to database vendors, which can be run in the Java EE container or run separately.
