怎么将hibernate.cfg.xml合并到applicationContext.xml中

Answer 1

spring整合hibernate的做法为

    1,整个项目搭建好spring框架

    2,在项目里添加hibernate的jar包

    3,spring的组件bean来管理hibernate

    4,具体的bean的写法如下:

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" > 
        <property name="driverClassName"> 
            <value>oracle.jdbc.driver.OracleDriver</value> 
        </property> 
        <property name="url"> 
            <value>jdbc\:oracle\:thin\:@localhost\:1521\:turing</value> 
        </property> 
        <property name="username"> 
            <value>sa</value> 
        </property> 
        <property name="password"> 
            <value>sa</value> 
        </property> 
    </bean>
    	<!-- spring提供的hibernate支持 -->
	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<!-- 数据源 -->
		<property name="dataSource" ref="dataSource" />
		<!-- hibernate属性设置 -->
		<property name="hibernateProperties">
			 <props>
				<prop key="hibernate.hbm2ddl.auto">update</prop>
				<prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
				<prop key="hibernate.show_sql">true</prop>
			</props>
		</property>
		<!-- 实体类声明 -->
        <property name="mappingDirectoryLocations">   
            <list>   
               <value>classpath:com/turing/manage/entity</value>
               <value>classpath:com/turing/system/entity</value>
            </list>   
        </property> 
	</bean>
