spinghibernatec3p0 的配置方法

 关键在于spring的配置

1、applicationcontext.xml

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">

        <property name="driverClass" value="com.mysql.jdbc.Driver" />

        <property name="jdbcUrl" value="jdbc:mysql://localhost/***?useUnicode=true&characterEncoding=gbk" />

        <property name="user" value="root" />

        <property name="password" value="mysql" />

<property name="minPoolSize" value="5" />

        <property name="maxPoolSize" value="30" />

<property name="initialPoolSize" value="10" />

<property name="maxIdleTime" value="60" />

        <property name="acquireIncrement" value="5" /> 

        <property name="maxStatements" value="0" />

        <property name="idleConnectionTestPeriod" value="60" />

        <property name="acquireRetryAttempts" value="30" />

        <property name="breakAfterAcquireFailure" value="true" /> 

        <property name="testConnectionOnCheckout" value="false" />

    </bean>

 

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

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

        <property name="configLocation" value="classpath:hibernate.cfg.xml"/>

        <property name="hibernateProperties">

            <props>

                <prop key="hibernate.dialect">

                    org.hibernate.dialect.MySQLDialect

                </prop>

            </props>

        </property>

    </bean>

 

2、hibernate.cfg.xml

<hibernate-configuration>

    <session-factory>

        <!-- Show and print nice SQL on stdout -->

        <property name="show_sql">false</property>

        <property name="format_sql">true</property>

 

             <mapping class="com.model.Host" />

    <mapping class="com.model.VmPerf" />

            <mapping class="com.model.UspVm" />

    </session-factory>

</hibernate-configuration>
