Spring配置SessionFactory

Spring的核心模块之一为依赖注入，普遍使用的为Set方式注入，那么下面将借助该方式配置数据源和SessionFactory。

直接引用hibernate.cfg.xml配置文件

这种方式需要提供hibernate.cfg.xml配置文件，在其中构造sessionFactory，并且持久层类的映射也在改文件配置，这步操作和Spring没有任何关系。产生关系是在spring的配置文件中，通过set方式注入到org.springframework.orm.hibernate3.LocalSessionFactoryBean类中，其对应属性为：configLocation。配置如下：

<span style="font-size: 18px;"><!-- 寻找hibernate.cfg.xml方式配置sessionfactory -->

<bean  id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation">
           <value>classpath:hibernate.cfg.xml</value>
</property>
</bean>
</span>

使用数据源配置SessionFactory

1、使用jdbc数据源

<!-- 配置jdbc数据源 -->
<!-- <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
	<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
	<property name="username" value="root"/>
	<property name="password" value="root"/>
	<property name="url" value="jdbc:mysql://localhost:3306/iess?useUnicode=true&characterEncoding=UTF8"/>
</bean>
 -->

2、使用c3p0数据源

<!-- 配置c3p0数据源 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
	<property name="driverClass" value="com.mysql.jdbc.Driver"/>
	<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/iess?useUnicode=true&characterEncoding=UTF8"/>
	<property name="maxIdleTime" value="25000"/>
	<property name="properties">
		<props>
			<prop key="user">root</prop>
			<prop key="password">root</prop>
			<prop key="c3p0.min_size">10</prop>
			<prop key="c3p0.max_size">100</prop>
			<prop key="c3p0.timeout">1800</prop>
			<prop key="c3p0.idle_test_period">3600</prop>
		</props>
	</property>
</bean>

3、结合数据源配置SessionFactory

<!-- 根据数据源创建sessionFactory -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
	<property name="dataSource" ref="dataSource"/>
	<property name="mappingResources">
		<list>
			<value>com/indigopacific/iessportal/persistent/Seal.hbm.xml</value>
			<value>com/indigopacific/iessportal/persistent/SealModel.hbm.xml</value>
			<value>com/indigopacific/iessportal/persistent/BranchInfo.hbm.xml</value>
			<value>com/indigopacific/iessportal/persistent/SealData.hbm.xml</value>
		</list>
	</property>
	<property name="hibernateProperties">
		<props>
			<prop key="hibernate.show_sql">true</prop>
			<prop key="hibernate.jdbc.fetch_size">30</prop>
			<prop key="hibernate.jdbc.batch_size">0</prop>
			<prop key="hibernate.max_fetch_depth">10</prop>
		</props>
	</property>
</bean>

spring配置事务

spring配置事务借助其AOP核心模块，其包括如下步骤：

1、配置事务管理器

2、配置Pointcut，定义事务作用范围

3、配置Advice,定义事务传播范围

其配置如下：

<!-- 配置事務管理器 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
	
	<property name="sessionFactory">
		<ref bean="sessionFactory"/>
	</property>
</bean>


<!-- 配置哪些类开启事务 -->
<aop:config>
	<aop:pointcut id="allMethod" expression="execution(* com.indigopacific.iessportal.Manager.*.*(..))"/>
	<aop:advisor pointcut-ref="allMethod" advice-ref="txAdvice"/>
</aop:config>


<tx:advice id="txAdvice" transaction-manager="transactionManager">
	<tx:attributes>
		<tx:method name="add*" propagation="REQUIRED"/>
		<tx:method name="del*" propagation="REQUIRED"/>
		<tx:method name="modify*" propagation="REQUIRED"/>
		<tx:method name="*" propagation="REQUIRED" read-only="true"/>
	</tx:attributes>
</tx:advice>
