Spring5整合Hibernate5

一、概述

　　Spring整合Hibernate有什麼好處？　　 1、由IOC容器來管理Hibernate的SessionFactory 　　2、讓Hibernate使用上Spring的聲明式事務

二、整合步驟:

步驟一：導包建立Maven項目SpringHibernate，并導入資料庫驅動包、Hibernate開發包以及Spring開發包，完成後項目的pom.xml檔案内容如下：  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>5.1.1.RELEASE</version> </dependency>  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>5.1.1.RELEASE</version> </dependency>  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>5.1.1.RELEASE</version> </dependency>  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>5.1.1.RELEASE</version> </dependency>  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.1.1.RELEASE</version> </dependency>  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>5.1.1.RELEASE</version> </dependency>  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>5.1.1.RELEASE</version> </dependency>  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>5.1.1.RELEASE</version> </dependency>  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>5.1.1.RELEASE</version> </dependency>  <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>5.3.6.Final</version> </dependency>  <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-c3p0</artifactId> <version>5.3.6.Final</version> </dependency> <dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc6</artifactId> <version>11.2.0.4</version> </dependency>  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>5.1.1.RELEASE</version> </dependency> 步驟二：建立Hibernate配置檔案 <session-factory>  <property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property> <property name="hibernate.show_sql">true</property> <property name="hibernate.format_sql">true</property> <property name="hbm2ddl.auto">update</property> </session-factory> 注意：   步驟三：建立實體類及其映射檔案： package com.cn.pojo; public class Book { private Integer id; private String bookName; private String isbn; private int price; private int stock; ...省略set/get方法... } Book.hbm.xml檔案 <hibernate-mapping> <class name="com.cn.pojo.Book" table="TB_BOOK"> <id name="id" type="java.lang.Integer"> <column name="ID" /> <generator class="native" /> </id> <property name="bookName" type="java.lang.String"> <column name="BOOKNAME" /> </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> 步驟四：建立DAO層、Service層 1、DAO層接口： package com.cn.dao; import java.util.List; import com.cn.pojo.Book; public interface IBookDao { public List<Book> findAll(); public String findBookById(int id); public void save(Book book); public void update(Book book); public void delete(int id); } 2、DAO層接口實作類： package com.cn.dao; public class BookDaoImpl implements IBookDao { private SessionFactory sessionFactory; public SessionFactory getSessionFactory() { return sessionFactory; } public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } //擷取和目前線程綁定的Seesion private Session getSession() { return sessionFactory.getCurrentSession(); } @Override public List<Book> findAll() { String hql = "from Book"; Query<Book> query = this.getSession().createQuery(hql); return query.list(); } @Override public String findBookById(int id) { // TODO Auto-generated method stub return null; } @Override public void save(Book book) { this.getSession().save(book); } @Override public void update(Book book) { // TODO Auto-generated method stub } @Override public void delete(int id) { // TODO Auto-generated method stub } } 3、服務層接口： public interface IBookService { public String findBookById(int id); public void saveBook(Book book); public List<Book> findAll(); } 4、服務層實作類： public class BookServiceImpl implements IBookService { private IBookDao dao; public IBookDao getDao() { return dao; } public void setDao(IBookDao dao) { this.dao = dao; } @Override public String findBookById(int id) { return null; } @Override public void saveBook(Book book) { dao.save(book); } @Override public List<Book> findAll() { return dao.findAll(); } } 步驟五：建立Spring配置檔案 1、applicationContext.xml檔案：  <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">  <property name="jdbcUrl" value="jdbc:oracle:thin:@localhost:1521:orcl"/> <property name="driverClass" value="oracle.jdbc.driver.OracleDriver"/> <property name="user" value="scott"/> <property name="password" value="root"/>  <property name="initialPoolSize" value="3"/> <property name="maxPoolSize" value="10"/> <property name="minPoolSize" value="1"/> <property name="acquireIncrement" value="3"/> <property name="maxIdleTime" value="60"/> </bean>  <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean" lazy-init="false">  <property name="dataSource" ref="dataSource"/> <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>  <property name="mappingLocations" value="classpath:com/cn/pojo/*.hbm.xml"/> </bean>  <import resource="classpath:applicationContext-beans.xml"/>  <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/> </bean>  <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="get*" read-only="true"/> <tx:method name="*"/> </tx:attributes> </tx:advice>  <aop:config proxy-target-class="true"> <aop:pointcut expression="execution(* com.cn.dao.*.*(..))" id="txPointcut"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/> </aop:config> 2、applicationContext-beans.xml <bean id="bookDao" class="com.cn.dao.BookDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="bookService" class="com.cn.dao.BookServiceImpl"> <property name="dao" ref="bookDao"></property> </bean> 測試： public class Test { private static String conf = "applicationContext.xml"; private static ApplicationContext context = null; private static IBookService bookService = null; public static void main(String[] args) { context = new ClassPathXmlApplicationContext(conf); bookService = context.getBean(BookServiceImpl.class); Book book = new Book(); book.setId(2); book.setBookName("Java程式設計"); book.setPrice(48); book.setStock(78); book.setIsbn("ISBN-001-0980"); bookService.saveBook(book); } }
