为什么hibernate连接提供商没有正确设置?

标签: java spring hibernate spring-mvc c3p0

我正在使用hibernate3和springframework。

我想为hibernate.connection.provider_class设置c3P0池,但显然设置了 LocalDataSourceConnectionProvider

在Hibernate.log中我看到了:

  

[级别:INFO]初始化连接提供程序:   org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider

我认为 org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider 是用于池化的hibernate默认连接提供程序类,因为我读到它在生产中使用是错误的。这是对的吗?

我想设置 org.hibernate.connection.C3P0ConnectionProvider 并使用c3p0管理池连接

这是我的hibernate配置:

<bean id="c3p0Datasource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
    destroy-method="close">
    <property name="driverClass">
        <value>oracle.jdbc.driver.OracleDriver</value>
    </property>
    <property name="jdbcUrl">
        <value>.......</value>
    </property>
    <property name="user">
        <value>.......</value>
    </property>
    <property name="password">
        <value>.......</value>
    </property>
</bean>

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

    <property name="dataSource">
        <ref local="c3p0Datasource" />
    </property>     

    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>     
            <prop key="hibernate.default_schema">.....</prop>
            <prop key="hibernate.hbm2ddl.auto">UPDATE</prop>
            <prop key="hibernate.cache.use_second_level_cache">false</prop>
            <prop key="hibernate.cache.use_query_cache">false</prop>
            <prop key="cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>             
            <prop key="hibernate.connection.zeroDateTimeBehavior">convertToNull</prop>
            <prop key="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.connection.isolation">2</prop>             
        </props>
    </property>
</bean>

有什么建议吗?
