hibernate只用注解时,spring的配置文件的配置如下
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName"> <value>com.mysql.jdbc.Driver</value> </property> <property name="url"> <value>jdbc:mysql://localhost:3306/oa</value> </property> <property name="username"> <value>root</value> </property> <property name="password"> <value>5519585</value> </property> <property name="maxActive"> <value>30</value> </property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="packagesToScan"> <list> <value>com.zhongkai.oa.model</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.show.sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop> </props> </property> </bean>
hibernate即用注解也用配置文件的情况:首先hibernate配置文件内容如下:
<?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <mapping resource="org/jbpm/graph/action/Script.hbm.xml"/> </session-factory> </hibernate-configuration>
然后spring配置文件内容:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName"> <value>com.mysql.jdbc.Driver</value> </property> <property name="url"> <value>jdbc:mysql://localhost:3306/oa</value> </property> <property name="username"> <value>root</value> </property> <property name="password"> <value>5519585</value> </property> <property name="maxActive"><value>30</value></property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="packagesToScan"> <list> <value>com.zhongkai.oa.model</value> </list> </property> <property name="configLocation"> <value>classpath:hibernate.cfg.xml</value> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.show.sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop> </props> </property> </bean>
在sessionFactoryBean中增加了元素
<property name="configLocation">
<value>classpath:hibernate.cfg.xml</value>
</property>
