本文详细介绍了Spring框架下使用TransactionProxyFactoryBean、BeanNameAutoProxyCreator和Springdao三种方式实现Hibernate Dao代理的方法，包括数据库配置、SessionFactory、TransactionManager、代理对象及DAO文件配置等关键步骤。

方法一利用TransactionProxyFactoryBean 代理（hibernate dao）

1 数据库设置

2 sessionFactory

<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
   <property name="configLocations">
   <list>
    <value>classpath*:/config/hibernate.cfg.xml</value>
   </list>
</property>
<property name="hibernateProperties">
   <props>
    <prop key="hibernate.dialect">
     org.hibernate.dialect.Oracle9Dialect
    </prop>
    <prop key="hibernate.show_sql">true</prop>
    <prop key="hibernate.cache.use_query_cache">false</prop>
    <prop key="hibernate.cache.use_second_level_cache">
     false
    </prop>
    <prop key="hibernate.cache.provider_class">
     org.hibernate.cache.EhCacheProvider
    </prop>
   </props>
</property>
</bean>

3 transactionManager

4 代理

<bean id="txProxyTemplate" abstract="true"
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager" ref="transactionManager" />
<property name="transactionAttributes">
   <props>
    <prop key="save*">PROPAGATION_REQUIRED</prop>
    <prop key="update*">PROPAGATION_REQUIRED</prop>
    <prop key="delete*">PROPAGATION_REQUIRED</prop>
    <prop key="execute*">PROPAGATION_REQUIRED</prop>
    <prop key="findBy*">PROPAGATION_REQUIRED</prop>
    <prop key="*">PROPAGATION_REQUIRED</prop>
   </props>
</property>
</bean>

5 被代理对象

6 DAO文件配置

方法二使用BeanNameAutoProxyCreator代理（hibernate dao）

1 dateSource

2 sessionFactory
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
   <ref bean="dataSource"/>
</property>
<property name="configLocation"
   value="classpath:hibernate.cfg.xml">
</property>
<property name="hibernateProperties">
            <props>
             <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
                <prop key="show_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.jdbc.batch_size">20</prop>
            </props>
        </property>
</bean>

3 transactionManager
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>

4 transactionInterceptor
<bean id="transactionInterceptor"
class="org.springframework.transaction.interceptor.TransactionInterceptor">

<property name="transactionManager" ref="transactionManager"/>
<property name="transactionAttributes">
   
   <props>
    <prop key="insert*">PROPAGATION_REQUIRED</prop>
    <prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
    <prop key="*">PROPAGATION_REQUIRED</prop>
   </props>
</property>
</bean>

5 代理

<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">

     <property name="beanNames">
            
            <list>
                 <value>svgWorkFlowManager</value>
    
            </list>
                </property>
        
        <property name="interceptorNames">
            <list>
                <value>transactionInterceptor</value>
            </list>
        </property>
    </bean>

6 DAO文件配置

方法三 Spring dao

1 dateSource

2 jdbcTemplate

3 dao配置

此bean 也可被有代理的manager 配置中引用，例如配置到以上方法一中的manager中
