spring中配置声明式事务的几种方式

xuxiaolei

(1)通过TransactionProxyFactoryBean来声明
<?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/beanshttp://www.springframework.org/schema/beans/spring-beans-2.0.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-2.0.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-2.0.xsd"><bean id="dataSource"class="org.springframework.jdbc.datasource.DriverManagerDataSource"><property name="driverClassName" value="org.hsqldb.jdbcDriver" /><property name="url" value="jdbc:hsqldb:hsql://localhost" /><property name="username" value="sa" /><property name="password" value="" /></bean><bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="mappingResources"><list><value>domain/Contestant.hbm.xml</value><value>domain/Event.hbm.xml</value><value>domain/Location.hbm.xml</value><value>domain/User.hbm.xml</value><value>domain/Voter.hbm.xml</value></list></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop><prop key="hibernate.show_sql">true</prop></props></property></bean><bean id="transactionManager"class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory" /></bean><bean id="parentService"class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"abstract="true"><property name="transactionManager" ref="transactionManager" /><property name="transactionAttributes"><props><prop key="add*">PROPAGATION_REQUIRED</prop><prop key="update*">PROPAGATION_REQUIRED</prop><prop key="persist*">PROPAGATION_REQUIRED</prop><prop key="delete*">PROPAGATION_REQUIRED</prop><prop key="*">PROPAGATION_SUPPORTS,readOnly</prop></props></property></bean><bean id="userDao" class="dao.UserDaoImpl"><property name="sessionFactory" ref="sessionFactory" /></bean><bean id="userServiceTarget" class="service.UserServiceImpl"><property name="userDao" ref="userDao" /></bean><bean id="userService" parent="parentService"><property name="target" ref="userServiceTarget" /><property name="proxyInterfaces" value="service.UserService" /></bean></beans> (2)通过aop:config
