使用数据源和使用 hibernateProperties 有什么区别。我想在我的应用程序中使用 c3P0 和 spring。我找到了两种方法,但我无法理解两者之间的区别
第一的:
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
depends-on="dataSource">
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.format_sql">false</prop>
<prop key="hibernate.use_sql_comments">false</prop>
</props>
</property>
<bean id="dataSource" destroy-method="close"
class="com.mchange.v2.c3p0.ComboPooledDataSource" >
<property name="maxPoolSize" value="10" />
<property name="numHelperThreads" value="5" />
</bean>
第二:
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
>
<property name="hibernateProperties">
<props>
<property name="hibernate.c3p0.maxSize" value="100" />
<property name="hibernate.c3p0.numHelperThreads" value="5" />>
</props>
</property>
</bean>
