spring+hibernate 两种整合方式配置文件的方法
作者:QH_JAVA
本篇文章主要介绍了spring+hibernate 两种整合方式配置文件的方法,主要有两种方式 1、注解方式 2、xml方式实现,有兴趣的可以了解一下。
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 "*"
