根据代理机制不同，有以下几种配置方式：

根据代理机制不同，有以下几种配置方式：

先定义一个DAO接口及实现类:

Java代码



public interface IUserDao {

public void insertUser(UserTable user);

}

实现类：

Java代码



public class UserDaoImpl extends HibernateDaoSupport implements IUserDao{

public void insertUser(UserTable user) {

getHibernateTemplate().saveOrUpdate(user);

}

}

第一种

为每个bean设置一个代理，这种是根据具体需求来定，如要对具体到每个交易进行事务操作的话，这个方式是最合适的；

Java代码



<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<!-- 每个bean都有一个代理 -->

<beans>

<!-- sessionFactory相当于spring datasource -->

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<property name="configLocation" value="classpath:hibernate.cfg.xml" />

<property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />

</bean>

<!-- 定义事务管理器（声明式的事务） -->

<bean id="transactionManager"

class="org.springframework.orm.hibernate3.HibernateTransactionManager">

<property name="sessionFactory" ref="sessionFactory" />

</bean>

<!-- 配置DAO -->

<bean id="userDao" class="org.lgh.spring.transaction2.UserDaoImpl">

<property name="sessionFactory" ref="sessionFactory" />

</bean>

<!-- 每个bean都有一个代理 <property name="target" ref="userDaoTarget" /> -->

<bean id="userDaoProxy"

class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">

<!-- 配置事务管理器 -->

<property name="transactionManager" ref="transactionManager" />

<property name="target" ref="userDao" />

<property name="proxyInterfaces" value="org.lgh.spring.transaction2.IUserDao" />

<!-- 配置事务属性 -->

<property name="transactionAttributes">

<props>

<prop key="*">PROPAGATION_REQUIRED</prop>

</props>

</property>

</bean>

</beans>

第二种:

所有的bean共享一个代理

Java代码



<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<!-- 所有的bean共享一个代理-->

<beans>

<bean id="sessionFactory"

class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<property name="configLocation" value="classpath:hibernate.cfg.xml" />

<property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />

</bean>

<!-- 定义事务管理器（声明式的事务） -->

<bean id="transactionManager"

class="org.springframework.orm.hibernate3.HibernateTransactionManager">

<property name="sessionFactory" ref="sessionFactory" />

</bean>

<!-- 所有的bean共享一个代理/> -->

<bean id="transactionBase"

class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"

lazy-init="true" abstract="true">

<!-- 配置事务管理器 -->

<property name="transactionManager" ref="transactionManager" />

<!-- 配置事务属性 -->

<property name="transactionAttributes">

<props>

<prop key="*">PROPAGATION_REQUIRED</prop>

</props>

</property>

</bean>

<!-- 配置DAO -->

<bean id="userDao" class="org.lgh.spring.transaction3.UserDaoImpl">

<property name="sessionFactory" ref="sessionFactory" />

</bean>

<!-- 所有的bean共享一个代理/> -->

<bean id="userDaoProxy" parent="transactionBase" >

<property name="target" ref="userDao" />

</bean>

</beans>

第三种:

使用拦截器 来配置你的事务，这个主要是进行一些方法调用前后进行一些其他事件的处理，如进行权限检查等...

代码如下:

Java代码



<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<!-- 使用拦截器 -->

<beans>

<bean id="sessionFactory"

class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<property name="configLocation" value="classpath:hibernate.cfg.xml" />

<property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />

</bean>

<!-- 定义事务管理器（声明式的事务） -->

<bean id="transactionManager"

class="org.springframework.orm.hibernate3.HibernateTransactionManager">

<property name="sessionFactory" ref="sessionFactory" />

</bean>

<bean id="transactionInterceptor"

class="org.springframework.transaction.interceptor.TransactionInterceptor">

<property name="transactionManager" ref="transactionManager" />

<!-- 配置事务属性 -->

<property name="transactionAttributes">

<props>

<prop key="*">PROPAGATION_REQUIRED</prop>

</props>

</property>

</bean>

<bean name="logger" class="org.lgh.spring.transaction4.SpringAOPInterceptor">

</bean>

<bean id="logBeforeAdvice" class="com.spring.advices.LogBeforeAdvice">

</bean>

<!-- 定义BeanNameAutoProxyCreator,该bean是个bean后处理器，无需被引用，因此没有id属性

这个bean后处理器，根据事务拦截器为目标bean自动创建事务代理 -->

<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">

<!-- 加上此句就不会抛出 $Proxy cannot be cast的异常啦-->

<property name="proxyTargetClass">

<value>true</value>

</property>

<property name="beanNames">

<list>

<!-- *Dao对应下面的userDao要对它进行拦截-->

<value>userDao</value>

</list>

</property>

<property name="interceptorNames">

<list>

<value>transactionInterceptor</value>

<value>logBeforeAdvice</value>

</list>

</property>

</bean>

<!-- 配置DAO -->

<bean id="userDao" class="org.lgh.spring.transaction4.UserDaoImpl">

<property name="sessionFactory" ref="sessionFactory" />

</bean>

<!-- 服务层 service-->

<bean id="userService" class="org.lgh.spring.transaction4.UserServiceImpl">

<property name="userDao" ref="userDao" />

</bean>

</beans>

第四种：

使用aop:config配置方式

Java代码



<?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:context="http://www.springframework.org/schema/context"

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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

<context:annotation-config />

<context:component-scan base-package="org.lgh.spring.transaction5" />

<bean id="sessionFactory"

class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<property name="configLocation" value="classpath:hibernate.cfg.xml" />

<property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />

</bean>

<!-- 定义事务管理器（声明式的事务） -->

<bean id="transactionManager"

class="org.springframework.orm.hibernate3.HibernateTransactionManager">

<property name="sessionFactory" ref="sessionFactory" />

</bean>

<tx:advice id="txAdvice" transaction-manager="transactionManager">

<tx:attributes>

<tx:method name="*" propagation="REQUIRED" />

</tx:attributes>

</tx:advice>

<aop:config proxy-target-class="true" >

<aop:pointcut id="interceptorPointCuts"

expression="execution(* org.lgh.spring.transaction5.*.*(..))" />

<aop:advisor advice-ref="txAdvice"

pointcut-ref="interceptorPointCuts" />

</aop:config>

<!-- 配置DAO -->

<bean id="userDao" class="org.lgh.spring.transaction5.UserDaoImpl">

<property name="sessionFactory" ref="sessionFactory" />

</bean>

</beans>

还有一种就是采用全注解方式：

代码如下:

Java代码



<?xml version="1.0" encoding="UTF-8"?>

<!--全注解 -->

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:context="http://www.springframework.org/schema/context"

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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

<context:annotation-config />

<context:component-scan base-package="org.lgh.spring.transaction6" />

<tx:annotation-driven proxy-target-class ="true" transaction-manager="transactionManager"/>

<bean id="sessionFactory"

class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<property name="configLocation" value="classpath:hibernate.cfg.xml" />

<property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />

</bean>

<!-- 定义事务管理器（声明式的事务） -->

<bean id="transactionManager"

class="org.springframework.orm.hibernate3.HibernateTransactionManager">

<property name="sessionFactory" ref="sessionFactory" />

</bean>

<!-- 配置DAO -->

<bean id="userDao" class="org.lgh.spring.transaction6.UserDaoImpl">

<property name="sessionFactory" ref="sessionFactory" />

</bean>

</beans>
