一、概述

Spring整合Hibernate有什么好处？ 1、由IOC容器来管理Hibernate的SessionFactory 2、让Hibernate使用上Spring的声明式事务

二、整合步骤

整合前准备：持久化类：@Entitypublic class Book{private Integer id;private String bookName;private String isbn;private int price;private int stock;public Integer getId（）{return id;}public void setId（Integer id）{this.id = id;}public String getBookName（）{return bookName;}public void setBookName（String bookName）{this.bookName = bookName;}public String getIsbn（）{return isbn;}public void setIsbn（String isbn）{this.isbn = isbn;}public int getPrice（）{return price;}public void setPrice（int price）{this.price = price;}public int getStock（）{return stock;}public void setStock（int stock）{this.stock = stock;}public Book（Integer id, String bookName, String isbn, int price, int stock）{super（）;this.id = id;this.bookName = bookName;this.isbn = isbn;this.price = price;this.stock = stock;}} Dao层：public interface BookDao{public String findBookById（int id）;public void saveBook（Book book）;} DaoImpl: @Repositorypublic class BookDaoImpl implements BookDao{@Autowiredprivate SessionFactory sessionFactory;//获取和当前线程绑定的Seesionprivate Session getSession（）{return sessionFactory.getCurrentSession（）;}public String findBookById（int id）{String hql="SELECT bookName from Book where id=？";Query query=getSession（）.createQuery（hql）.setInteger（0, id）;String str= query.uniqueResult（）.toString（）;return str;}public void saveBook（Book book）{getSession（）.save（book）;}} Service层：public interface BookService{public String findBookById（int id）;public void saveBook（Book book）;} ServiceImpl： @Servicepublic class BookServiceImpl implements BookService{@Autowiredprivate BookDao bookDao;public String findBookById（int id）{return bookDao.findBookById（id）;}public void saveBook（Book book）{bookDao.saveBook（book）;}}

1、加入Hibernate

加入hibernate jar包
添加Hibernate的配置文件：hibernate.cfg.xml

<？xml version="1.0" encoding="UTF-8"？><！DOCTYPE hibernate-configuration PUBLIC"-//Hibernate/Hibernate Configuration DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><hibernate-configuration><session-factory><！-- 配置Hibernate的基本属性 --><！-- 1.数据源配置到IOC容器中 --><！-- 2.关联的.hbm.xml也在IOC容器配置SessionFactory实例 --><！-- 3.配置Hibernate的基本属性：方言，SQL显示及格式化，生成数据表的策略以及二级缓存 --><property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property><property name="hibernate.show_sql">true</property><property name="hbm2ddl.auto">update</property></session-factory></hibernate-configuration>

编写持久化类对应的.hbm.xml文件

<？xml version="1.0"？><！DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><！-- Generated 2016-3-15 16:30:05 by Hibernate Tools 3.4.0.CR1 --><hibernate-mapping><class name="com.demo.ssm.po.Book" table="BOOK"><id name="id" type="java.lang.Integer"><column name="ID" /><generator class="native" /></id><property name="bookName" type="java.lang.String"><column name="BOOK_NAME" /></property><property name="isbn" type="java.lang.String"><column name="ISBN" /></property><property name="price" type="int"><column name="PRICE" /></property><property name="stock" type="int"><column name="STOCK" /></property></class></hibernate-mapping>

2、加入Spring

加入spring jar包
加入Spring配置文件

<？xml version="1.0" encoding="UTF-8"？><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:tx="http://www.springframework.org/schema/tx"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd"><context:component-scan base-package="com.demo.ssm"></context:component-scan><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"><property name="driverClassName" value="com.mysql.jdbc.Driver" /><property name="url" value="jdbc:mysql://localhost/test" /><property name="username" value="root"></property><property name="password" value="281889"></property></bean><bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" lazy-init="false"><！-- 注入datasource，给sessionfactoryBean内setdatasource提供数据源 --><property name="dataSource" ref="dataSource" /><property name="configLocation" value="classpath:hibernate.cfg.xml"></property><！-- //加载实体类的映射文件位置及名称 --><property name="mappingLocations" value="classpath:com/demo/ssm/po/*.hbm.xml"></property></bean><！-- 配置Spring声明式事务 --><bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"></property></bean> <！-- 配置事务事务属性 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="get*" read-only="true"/><tx:method name="*"/></tx:attributes></tx:advice><！-- 配置事务切点，并把切点和事务属性关联起来 --><aop:config><aop:pointcut expression="execution（* com.demo.ssm.daoImpl.*.*（..））" id="txPointcut"/><aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/></aop:config></beans>

3、编写测试类

public class BookDaoImplTest{private ApplicationContext context=null;private BookService bookService=null;{ context= new ClassPathXmlApplicationContext（"applicationContext.xml"）; bookService=context.getBean（BookService.class）;}@Testpublic void test（）{DataSource dataSource=（DataSource） context.getBean（DataSource.class）;System.out.println（dataSource）;}@Testpublic void test2（）{String bookName=bookService.findBookById（1）;System.out.println（bookName）;}@Testpublic void test3（）{bookService.saveBook（new Book（2, "Android源码分析", "1002", 45, 10））;}}Hibernate3.1.2_中文文档PDF http://www.linuxidc.com/Linux/2016-02/128462.htmHibernate学习入门教程 http://www.linuxidc.com/Linux/2015-08/121498.htm在Hibernate中开启日志 http://www.linuxidc.com/Linux/2015-07/120499.htmHibernate+JUnit测试实体类生成数据库表 http://www.linuxidc.com/Linux/2015-07/120161.htmHibernate整体理解 http://www.linuxidc.com/Linux/2014-07/104405.htmHibernate的映射机制 http://www.linuxidc.com/Linux/2014-12/110265.htmHibernate 的详细介绍：请点这里
