Spring管理hibernate的事务的方法

1.采用标注法

在某个方法前面添加事务标注

如，用银行存款进行买股票，则存款减少

@Transactional(propagation=Propagation.REQUIRED,rollbackFor=StockException.class)
public void buyStock(String accName, double amt, String stockName) throws StockException {
// TODO Auto-generated method stub
Account a = accountDAO.findByName(accName);
a.setBalance(a.getBalance() - amt);
accountDAO.save(a);
if(1==1)
throw new StockException();
Stock s = stockDAO.findByName(stockName);
s.setQty(s.getQty() + amt/s.getPrice());
stockDAO.save(s);
}

配置文件设置：

<!-- dataSource，配置数据源 -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
<property name="url">
<value>jdbc:mysql://localhost:3306/tarena</value>
</property>
<property name="username">
<value>root</value>
</property>
<property name="password">
<value>1234</value>
</property>
</bean>
<!-- SessionFactory -->
<bean id="mySessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="mappingResources">
<list>
<value>entity/Account.hbm.xml</value>
<value>entity/Stock.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">create-drop</prop>
</props>
</property>
</bean>
<!-- HibernateTransactionManager 配置事务管理-->
<bean id="myTransactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">
<ref bean="mySessionFactory" />
</property>
</bean>
<!-- DAO配置dao接口实现类 -->
<bean id="abstactDAO" abstract="true">
<property name="sessionFactory" ref="mySessionFactory" />
</bean>
<bean id="accountDAO" class="dao.impl.AccountDAOHibernateImpl"
parent="abstactDAO" />
<bean id="stockDAO" class="dao.impl.StockDAOHibernateImpl"
parent="abstactDAO" />
<!-- service配置业务接口实现类 -->
<bean id="stockProcessService"
class="service.impl.StockProcessServiceSpringImpl3">
<property name="accountDAO" ref="accountDAO" />
<property name="stockDAO" ref="stockDAO" />
</bean>

<!--配置事务-->
<tx:annotation-driven transaction-manager="myTransactionManager" />

2.不用标注、代理，

方法的实现就是照常写，配置文件有所变化

<!-- dataSource -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
<property name="url">
<value>jdbc:mysql://localhost:3306/tarena</value>
</property>
<property name="username">
<value>root</value>
</property>
<property name="password">
<value>1234</value>
</property>
</bean>
<!-- SessionFactory -->
<bean id="mySessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="mappingResources">
<list>
<value>entity/Account.hbm.xml</value>
<value>entity/Stock.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">create-drop</prop>
</props>
</property>
</bean>
<!-- HibernateTransactionManager -->
<bean id="myTransactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">
<ref bean="mySessionFactory" />
</property>
</bean>
<!-- DAO配置抽象父类，被dao接口实现类继承 -->
<bean id="abstactDAO" abstract="true">
<property name="sessionFactory" ref="mySessionFactory" />
</bean>
<bean id="accountDAO" class="dao.impl.AccountDAOHibernateImpl"
parent="abstactDAO" />
<bean id="stockDAO" class="dao.impl.StockDAOHibernateImpl"
parent="abstactDAO" />
<!-- serviceTarget -->
<bean id="stockProcessServiceTarget"
class="service.impl.StockProcessServiceSpringImpl">
<property name="accountDAO" ref="accountDAO" />
<property name="stockDAO" ref="stockDAO" />
</bean>
<!-- 配置事务代理 -->
<bean id="stockProcessService"
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager">
<ref bean="myTransactionManager" />
</property>
<property name="target">
<ref bean="stockProcessServiceTarget" />
</property>
<property name="transactionAttributes">
<props>
<prop key="find*">PROPAGATION_SUPPORTS,readOnly</prop>
<prop key="open*">PROPAGATION_REQUIRED</prop>
<prop key="buyStock">PROPAGATION_REQUIRED,-StockException</prop>
</props>
</property>
</bean>
