1. What does Spring integration Hibernate integrate? 1). There are IOC containers to manage Hibernate's SessionFactory2). Let Hibernate use declarative transaction 2 on Spring. Integration steps: 1). Join Hibernate①. Jar Package ②. Add Hibernate configuration file: Hibernate.cfg.xml③. The. hbm.xml file that corresponds to the persisted class has been written. 2). Join Spring①. Jar Package ②. Join Spring's configuration file 3). Integration. 3. Writing code

Project structure:

Bookshopdao Code:

Package Com.atguigu.spring.hibernate.dao;public interface Bookshopdao {//per ISBN get book price public int FINDBOOKPRICEBYISBN ( String ISBN);//The Inventory of the updated number. Keep the ISBN corresponding in stock-1public void Updatebookstock (String ISBN);//update the user's account balance: Make username balance-pricepublic void Updateuseraccoun T (String username, int price);}

Bookshopdaoimpl Code:

Package Com.atguigu.spring.hibernate.dao.impl;import Org.hibernate.query;import Org.hibernate.session;import Org.hibernate.sessionfactory;import Org.springframework.beans.factory.annotation.autowired;import Org.springframework.stereotype.repository;import Com.atguigu.spring.hibernate.dao.bookshopdao;import Com.atguigu.spring.hibernate.exceptions.bookstockexception;import Com.atguigu.spring.hibernate.exceptions.UserAccountException, @Repositorypublic class Bookshopdaoimpl implements Bookshopdao {@Autowiredprivate sessionfactory sessionfactory;//not recommended Hibernatetemplate and hibernatedaosupport// Because this causes the Dao and Spring APIs to be coupled//portability-poor//private hibernatetemplate hibernatetemplate;//gets and the current thread binds to the Session. Private Session getsession () {return sessionfactory.getcurrentsession ();} @Overridepublic int Findbookpricebyisbn (string ISBN) {string hql = "Select B.price from book b WHERE b.isbn =?"; Query query = getsession (). CreateQuery (HQL). SetString (0, ISBN); return (Integer) Query.uniqueresult ();} @Overridepublic void Updatebookstock (String ISBN) {//Verify that the inventory is sufficient. String hql2 = "Select B.stock from book b WHERE b.isbn =?"; int stock = (int) getsession (). CreateQuery (HQL2). SetString (0, ISBN). Uniqueresult (); if (stock = = 0) {throw new Bookstockexception ("Insufficient stock!");} String hql = "UPDATE book b SET b.stock = b.stock-1 WHERE b.isbn =?"; GetSession (). CreateQuery (HQL). SetString (0, ISBN). executeupdate ();  @Overridepublic void Updateuseraccount (string username, int price) {//Verify that the balance is sufficient String hql2 = "Select A.balance from Account A WHERE a.username =? "; int balance = (int) getsession (). CreateQuery (HQL2). setString (0, username). Uniqueresult (); if (balance < price) {throw New Useraccountexception ("Insufficient balance!");} String hql = "UPDATE account a SET a.balance = a.balance-?" WHERE a.username =? "; GetSession (). CreateQuery (HQL). Setinteger (0, Price). setString (1, username). Executeupdate ();}}

Unit Test class Springhibernatetest code:

Package Com.atguigu.spring.hibernate.test;import Java.sql.sqlexception;import Java.util.arrays;import Javax.sql.datasource;import Org.junit.test;import Org.springframework.context.applicationcontext;import Org.springframework.context.support.classpathxmlapplicationcontext;import Com.atguigu.spring.hibernate.service.bookshopservice;import Com.atguigu.spring.hibernate.service.cashier;public Class Springhibernatetest {private ApplicationContext CTX = null;private Bookshopservice bookshopservice = null;private C Ashier cashier = null; {CTX = new Classpathxmlapplicationcontext ("Applicationcontext.xml"); Bookshopservice = Ctx.getbean ( Bookshopservice.class); cashier = Ctx.getbean (Cashier.class);} @Testpublic void Testcashier () {cashier.checkout ("AA", Arrays.aslist ("1001", "1002"));} @Testpublic void Testbookshopservice () {bookshopservice.purchase ("AA", "1001");} @Testpublic void Testdatasource () throws SQLException {DataSource DataSource = Ctx.getbean (Datasource.class); System.out.println (Datasource.getConnection ());}}
