Hibernate 4.x 整合 Spring 3.x

Spring3.x和Hibernate4的整合只支援到 4.2(第4版的最後一版為4.3)，整合方式和Hibernate3.x一樣，但Hibernate4不支援HibernateTemplate了，getCurrentSession也差不多，我只改兩個地方就可以run了

<bean id="sf"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <!-- ... -->
</bean>
    
<bean id="txManagerHibernate"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <!-- ... -->
</bean>

※其實就是將Hibernate3改成Hibernate4而已

※如果transactionManager使用JDBC的org.springframework.jdbc.datasource.DataSourceTransactionManager，Hibernate3.x整合Spring3.x可以使用getCurrentSession，而Hibernate4.2之前整合Spring3.x會出「No Session found for current thread」的錯，網路上說加什麼thread，我試沒有用，而JTA的我沒試過

雖然只是改成4，我還是將這次的pom檔列出來好了

pom.xml

    <artifactId>hibernate-core</artifactId>
    <version>4.2.21.Final</version>
</dependency>

※applicationContext.xml和hibernate.cfg.xml都有的設定

applicationContext.xml

<context:annotation-config />
<context:component-scan base-package="dao.impl" />
    
<bean id="ds" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
    <property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:orcl" />
    <property name="username" value="username" />
    <property name="password" value="password" />
</bean>
    
<bean id="sf"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="ds" />
    <property name="configLocations" value="classpath:hibernate.cfg.xml" />
</bean>
    
<tx:annotation-driven transaction-manager="txManagerHibernate" />
    
<bean id="txManagerHibernate"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sf" />
</bean>
    
<tx:advice id="xxx" transaction-manager="txManagerHibernate">
    <tx:attributes>
        <tx:method name="update*" propagation="REQUIRED" />
        <tx:method name="insert*" propagation="REQUIRED" />
        <tx:method name="edit*" propagation="REQUIRED" />
        <tx:method name="save*" propagation="REQUIRED" />
        <tx:method name="add*" propagation="REQUIRED" />
        <tx:method name="remove*" propagation="REQUIRED" />
        <tx:method name="delete*" propagation="REQUIRED" />
        <tx:method name="get*" propagation="REQUIRED" read-only="true" />
        <tx:method name="find*" propagation="REQUIRED" read-only="true" />
        <tx:method name="load*" propagation="REQUIRED" read-only="true" />
    </tx:attributes>
</tx:advice>
    
<aop:config>
    <aop:pointcut id="ooo" expression="execution(* dao.impl*.*(..))" />
    <aop:advisor advice-ref="xxx" pointcut-ref="ooo" />
</aop:config>

※如果還想針對特定的方法才執行transaction就要加tx:advice和aop:config，一般都是針對service，而我自己測試用，懶的寫service，所以直接跳到dao，可參考官網

pom.xml

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>1.8.4</version>
</dependency>

※加這個是因為aop會用到，而我沒有，只好下載了，spring3.x整合hibernate3.x和4.2之前的我都試過，都是OK的

hibernate.cfg.xml

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.format_sql">true</property>
        <property name="hibernate.use_sql_comments">true</property>
        <mapping resource="hbm/Dept.hbm.xml" />
    </session-factory>
</hibernate-configuration>

※hbm.xml原本是寫在LocalSessionFactoryBean裡面的mappingResources屬性，也可寫在這裡，兩者選其一即可
