applicationContenxt.xml是这样配置的

<context:annotation-config />
<!-- 设定Spring 去哪些包中找Annotation -->
<context:component-scan base-package="com.tianbo" />

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="${jdbc.driverClassName}" />
    <property name="url" value="${jdbc.url}" />
    <property name="username" value="${jdbc.username}" />
    <property name="password" value="${jdbc.password}" />
    <!-- 配置连接池的初始值 -->
    <property name="initialSize" value="1" />
    <!-- 连接池的最大值 -->
    <!-- <property name="maxActive" value="500"/> -->
    <!-- 最大空闲时，当经过一个高峰之后，连接池可以将一些用不到的连接释放，一直减少到maxIdle为止 -->
    <!-- <property name="maxIdle" value="2"/> -->
    <!-- 当最小空闲时，当连接少于minIdle时会自动去申请一些连接 -->
    <property name="minIdle" value="1" />
    <property name="maxActive" value="100" />
    <property name="maxIdle" value="20" />
    <property name="maxWait" value="1000" />
</bean>
<!-- 导入Src目录下的jdbc.properties文件 -->
<context:property-placeholder location="classpath:jdbc.properties" />
<!--创建Spring的SessionFactory工厂 -->
<!-- 如果使用的是Annotation的方式，不能使用LocalSessionFactoryBean,而应该使用 org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean -->
<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <!-- 注入数据源 -->
    <property name="dataSource" ref="dataSource" />
    <!-- 设置Spring取那个包中查找相应的实体类 -->
    <property name="packagesToScan">
        <value>com.tianbo.po</value>
    </property>
    <property name="hibernateProperties">
        <!-- <value> hibernate.dialect=org.hibernate.dialect.HSQLDialect </value> -->
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
            <prop key="hibernate.format_sql">false</prop>
        </props>
    </property>
</bean>
<!-- 开启HibernateTemplate，并且为其注入SessionFactory
使用HibernateTemplate不太方便的就是要获取session得通过getSessionFactory()方法获取 -->
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!-- 配置Spring的事务处理 -->
<!-- 创建事务管理器-->
<bean id="txManager"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<aop:config>
<!-- 设置pointCut表示哪些方法要加入事务处理 -->
<!-- 以下的事务是声明在DAO中，但是通常都会在Service来处理多个业务对象逻辑的关系，注入删除，更新等，此时如果在执行了一个步骤之后抛出异常
    就会导致数据不完整，所以事务不应该在DAO层处理，而应该在service，这也就是Spring所提供的一个非常方便的工具，声明式事务 -->
    <aop:pointcut id="allMethods"
        expression="execution(* com.tianbo.serviceimpls.*.*(..))" />
    <!-- 通过advisor来确定具体要加入事务控制的方法 -->
    <aop:advisor advice-ref="txAdvice" pointcut-ref="allMethods" />
</aop:config>

<tx:advice id="txAdvice" transaction-manager="txManager">
    <tx:attributes>
    <!-- 让所有的方法都加入事务管理，为了提高效率，可以把一些查询之类的方法设置为只读的事务 -->
        <tx:method name="*" propagation="REQUIRED" read-only="true"/>
        <!-- 以下方法都是可能设计修改的方法，就无法设置为只读 -->
        <tx:method name="add*" propagation="REQUIRED"/>
        <tx:method name="del*" propagation="REQUIRED"/>
        <tx:method name="update*" propagation="REQUIRED"/>
        <tx:method name="save*" propagation="REQUIRED"/>
    </tx:attributes>
</tx:advice>
