之前的文章都是讲解springmvc+spring+mybatis 的整合,而很少有springmvc+spring+hibernate 因为工作的需要,最近在使用hibernate 所以下面我们来看看 spring整合hibernate的配置文件,这里只说spring+hibernate 的配置文件而不说springmvc 因为这些是不用变的。
spring整合hibernate 有两种方式 1、注解方式 2、xml方式实现
1、注解方式实现:
applicationcontext.xml配置文件:
<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemalocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:component-scan base-package="com.test" /> <bean class="org.springframework.beans.factory.config.propertyplaceholderconfigurer"> <property name="locations"> <list> <value>classpath:jdbc.properties</value> </list> </property> </bean> <bean id="c3p0datasource" destroy-method="close" class="com.mchange.v2.c3p0.combopooleddatasource"> <property name="driverclass" value="${driverclass}" /> <property name="jdbcurl" value="${url}" /> <property name="user" value="${user}" /> <property name="password" value="${password}" /> <property name="initialpoolsize" value="${initialpoolsize}" /> <property name="minpoolsize" value="${minpoolsize}" /> <property name="maxpoolsize" value="${maxpoolsize}" /> <property name="maxidletime" value="${maxidletime}" /> </bean> <bean id="sessionfactory" class="org.springframework.orm.hibernate4.localsessionfactorybean"> <property name="datasource" ref="c3p0datasource" /> <property name="packagestoscan"> <list> <value>com.test.bean</value> </list> </property> <property name="hibernateproperties"> <props> <prop key="hibernate.dialect">${dialect}</prop> <prop key="hibernate.show_sql">${show_sql}</prop> <prop key="hibernate.format_sql">${format_sql}</prop> <prop key="hibernate.use_sql_commants">${use_sql_comments}</prop> <prop key="hibernate.hbm2ddl.auto">${hbm2ddl.auto}</prop> </props> </property> </bean> <bean id="txmanager" class="org.springframework.orm.hibernate4.hibernatetransactionmanager"> <property name="sessionfactory" ref="sessionfactory" /> </bean> <tx:advice id="txadvice" transaction-manager="txmanager"> <tx:attributes> <tx:method name="get*" read-only="true" /> <tx:method name="*" /> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="bizmethods" expression="execution(* com.test.biz.*.*(..))" /> <aop:advisor advice-ref="txadvice" pointcut-ref="bizmethods" /> </aop:config> </beans>
2.xml方式实现
applicationcontext.xml配置:
<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <!-- 让spring 去读取指定路径下的资源文件 --> <bean class="org.springframework.beans.factory.config.propertyplaceholderconfigurer"> <property name="locations" value="classpath:jdbc.properties"/> </bean> <!-- 配置c3p0连接池 --> <bean id="c3p0source" class="com.mchange.v2.c3p0.combopooleddatasource" destroy-method="close"> <property name="driverclass" value="${driverclass}" /> <property name="jdbcurl" value="${url}" /> <property name="user" value="${user}" /> <property name="password" value="${password}" /> <property name="initialpoolsize" value="${initialpoolsize}" /> <property name="minpoolsize" value="${minpoolsize}" /> <property name="maxpoolsize" value="${maxpoolsize}" /> <property name="maxidletime" value="${maxidletime}" /> </bean> <!-- 配置sessionfactory --> <bean id="sessionfactory" class="org.springframework.orm.hibernate4.localsessionfactorybean"> <property name="datasource" ref="c3p0source" /> <property name="mappingresources"> <list> <value>/com/cdzg/spring/bean/user.hbm.xml</value> </list> </property> <property name="hibernateproperties"> <props> <prop key="hibernate.dialect">${dialect}</prop> <prop key="hibernate.hbm2ddl.auto">${hbm2ddl.auto}</prop> <prop key="hibernate.show_sql">${show_sql}</prop> <prop key="hibernate.format_sql">${format_sql}</prop> <prop key="hibernate.use_sql_comments">${use_sql_comments}</prop> </props> </property> </bean> <!-- 配置事务管理器 --> <bean id="txmanager" class="org.springframework.orm.hibernate4.hibernatetransactionmanager"> <property name="sessionfactory" ref="sessionfactory" /> </bean> <!-- 定义事务通知 --> <tx:advice id="txadvice" transaction-manager="txmanager"> <tx:attributes> <tx:method name="get*" read-only="true"/> <tx:method name="*"/> </tx:attributes> </tx:advice> <!-- 定义事务切面,并应用事务通知 --> <aop:config> <aop:pointcut id="xxxbizimpl" expression="execution(* com.cdzg.spring.biz.*.*(..))"/> <aop:advisor pointcut-ref="xxxbizimpl" advice-ref="txadvice"/> </aop:config> <bean id="userdaoimpl" class="com.cdzg.spring.dao.impl.userdaoimpl"> <property name="sessionfactory" ref="sessionfactory" /> </bean> <bean id="userbizimpl" class="com.cdzg.spring.biz.impl.userbizimpl"> <property name="userdao" ref="userdaoimpl" /> </bean> <bean id="useraction" class="com.cdzg.spring.web.actions.useraction"> <property name="userbiz" ref="userbizimpl" /> </bean> </beans>
两种配置最大的区别就是注解方式不用在写o/r映射配置文件而xml方式实现的要配置o/r映射配置文件
注解的这种方式,直接扫描bean包就可以,剩下的对应关系由框架完成
而xml配置方式要配置o/r 映射文件并在这里指定文件,如果多的话可以使用通配符 "*"
