Sping2
及
Hibernate3
都是如今流行的請量級框架，如何將兩者進(jìn)行整合呢，目前很多資料討論的都是老版本的整合方式，下面給出這兩種框架的新版整合方式。
1
配置數(shù)據(jù)源
??? <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
??? <property name="driverClassName">
??????? <value>com.microsoft.jdbc.sqlserver.SQLServerDriver</value>
??? </property>
??? <property name="url">
??????? <value>jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=webguide</value>
??? </property>
??? <property name="username">
??????? <value>sa</value>
??? </property>
??? <property name="password">
??????? <value>talent</value>
??? </property>
?? </bean>
2
配置
Hibernate
SessionFactory
<bean id="mySessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
?????? <property name="mappingResources">
?????? <!—Hibernate
映射文件列表
-->
?????????? <list>
?????????????? <value>Greeting.hbm.xml</value>
?
?????????</list>
?????? </property>
?????? <property name="hibernateProperties">
?????????? <props>
?????????????? <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
??????????????? <prop key="hibernate.show_sql">true</prop>
???
????
???????<prop key="hbm2ddl.auto">update</prop>
?????????? </props>
?????? </property>
?????? <property name="dataSource">
?????????? <ref bean="myDataSource"/>
?????? </property>
??????
?? </bean>
3
配置事務(wù)
? <bean id="myTranAttri" class="org.springframework.transaction.interceptor.DefaultTransactionAttribute">
???
<property name="propagationBehaviorName">
???
??? <value>PROPAGATION_REQUIRED</value>
???
</property>
??? </bean>
??? <bean id="transactionAttributeSource" class="org.springframework.transaction.interceptor.MatchAlwaysTransactionAttributeSource">
???
<property name="transactionAttribute">
???
??? <ref bean="myTranAttri"/>
???
</property>
??? </bean>
??? <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
??????
? <property name="sessionFactory">
??????????? <ref bean="mySessionFactory"/>
??????? </property>
??? </bean>
??????????
??? <bean id="txInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor" lazy-init="true">
?????? <property name="transactionManager">
?????????? <ref bean="transactionManager"/>
?????? </property>
?????? <property name="transactionAttributeSource">
?????????? <ref bean="transactionAttributeSource"/>
?????? </property>
??? </bean>

使用
Hibernate
實體
方法一：采用
AOP
的方式
package hibernate.integration.entity;
?
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.SessionFactoryUtils;
?
/**
?* @author chao cai
?*
?* TODO To change the template for this generated type comment go to
?* Window - Preferences - Java - Code Style - Code Templates
?*/
public class GreetingLogic3 implements IGreetingLogic{
??? private SessionFactory sessionFactory;
??? /* (non-Javadoc)
???
?* @see hibernate.integration.entity.IGreetingLogic#loadGreeting(java.lang.Integer)
???
?*/
??? public Greeting loadGreeting(Integer id) {
?????? Session session = sessionFactory.getCurrentSession();
?????? Greeting greeting=(Greeting) session.get(Greeting.class,id);
?????? return greeting;
???
??? }
?
?
??? /**
???
?* @return Returns the sessionFactory.
???
?*/
??? public SessionFactory getSessionFactory() {
?????? return sessionFactory;
??? }
??? /**
???
?* @param sessionFactory The sessionFactory to set.
???
?*/
??? public void setSessionFactory(SessionFactory sessionFactory) {
?????? this.sessionFactory = sessionFactory;
??? }
}
代碼樣例：
package hibernate.integration.entity;
?
/**
?* @author chao cai
?*
?* TODO To change the template for this generated type comment go to
?* Window - Preferences - Java - Code Style - Code Templates
?*/
public interface IGreetingLogic {
??? public Greeting loadGreeting(Integer id);
}
?
配置
??? <bean id="myGreetingLogic" class="org.springframework.aop.framework.ProxyFactoryBean">
??????? <property name="proxyInterfaces">
??????????? <value>hibernate.integration.entity.IGreetingLogic</value>
??????? </property>
??????? <property name="interceptorNames">
??????????? <list>
??????????????? <value>txInterceptor</value>
??????????????? <value>myHibernateInterceptor</value>
?????????????
??????????? </list>
??????? </property>
??????? <property name="target">
????
???
<ref bean="greetingLogic3"/>
??????? </property>
</bean>
客戶端代碼：
AbstractApplicationContext context=new FileSystemXmlApplicationContext("spring-hibernate.xml");
IGreetingLogic gl=(IGreetingLogic) context.getBean("myProductDao");
?????? greeting=gl.loadGreeting(new Integer(1));
?????? System.out.println(greeting.getGreeting());
?
方法二：采用
HibernateDaoSupport
代碼：
package hibernate.integration.entity;
?
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.SessionFactoryUtils;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
?
/**
?* @author Chao Cai
?*
?* TODO To change the template for this generated type comment go to
?* Window - Preferences - Java - Code Style - Code Templates
?*/
public class GreetingLogic extends HibernateDaoSupport implements IGreetingLogic{
???
??? public Greeting loadGreeting(Integer id){
?????? Session session = SessionFactoryUtils.getSession(getSessionFactory(), false);
?????? Greeting greeting=(Greeting) session.get(Greeting.class,id);
?????? return greeting;
??????
??? }
}
??? <bean id="greetingLogic" class="hibernate.integration.entity.GreetingLogic">
????????? <property name="sessionFactory">
??????????? <ref bean="mySessionFactory"/>
??????? </property>
??? </bean>
