<!--加载我的资源文件：dbconn/prpperties -->
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:dbconn.properties</value>

<!--资源文件如下：
#oracle10g
#jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
#jdbc.url=jdbc:oracle:thin:@localhost:1521:orcl
#jdbc.username=scott
#jdbc.password=zitadmin
#hibernate.dialect=org.hibernate.dialect.Oracle10gDialect
#mysql
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test
jdbc.username=root
jdbc.password=root
hibernate.dialect=org.hibernate.dialect.MySQLDialect
这个文件要重新建立并且我给它命名为：dbconn.properties
-->
<!-- ${ } 是获取资源文件里的值-->
<!--第一种是： dbcp配置
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName">
<value>${jdbc.driverClassName}</value>
</property>
<property name="url">
<value>${jdbc.url}</value>
</property>
<property name="username">
<value>${jdbc.username}</value>
</property>
<property name="password">
<value>${jdbc.password}</value>
</property>
<property name="maxActive" value="20" />
<property name="minIdle" value="1" />
<property name="initialSize" value="1" />
<property name="maxWait" value="20" />
</bean>
-->
<!-- 第二种：c3p0配置（首选：因为hibernate官方的人说dbcp有bug） -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="org.gjt.mm.mysql.Driver"/>
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="initialPoolSize" value="1" />
<property name="minPoolSize" value="1" />
<property name="maxPoolSize" value="300" />
<!-- 最大空闲时间，60表示60秒内无使用，则连接被丢弃，如果为0,表示始终保持连接 Default:0-->
<property name="maxIdleTime" value="60" />
<!-- 当连接池中的连接耗尽时，c3p0一次同时获取的连接数 Default:3 -->
<property name="acquireIncrement" value="5" />
<!-- 每60秒检查所有连接池中的空闲连接 Default:0-->
<property name="idleConnectionTestPeriod" value="60" />
</bean>
<!-- 得到sessionFactory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<!--
<prop key="hibernate.current_session_context_class">thread</prop>
-->
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
<!-- 注解的包或者类（此类是用 hibernate注解方式的） annotatedClasses：加载指定类 packagesToScan:加载指定包-->
<property name="packagesToScan">
<list>
<value>com.ad.model</value>
</list>
</property>
</property>
<!--非注解方式
<property name="mappingResources">
<list>
<value>com/ad/model/User.hbm.xml</value>
</list>
</property>
-->
</bean>
</beans>
