spring 注解事务管理配置方案

根据代理机制的不同，总结了五种Spring事务的配置方式，配置文件如下：

第一种方式：每个Bean都有一个代理

Java代码

1. <bean id="sessionFactory"
2. class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
3. <property name="configLocation" value="classpath:hibernate.cfg.xml" />
4. <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />
5. </bean>
7. <!-- 定义事务管理器（声明式的事务） -->
8. <bean id="transactionManager"
9. class="org.springframework.orm.hibernate3.HibernateTransactionManager">
10. <property name="sessionFactory" ref="sessionFactory" />
11. </bean>
13. <!-- 配置DAO -->
14. <bean id="userDaoTarget" class="com.bluesky.spring.dao.UserDaoImpl">
15. <property name="sessionFactory" ref="sessionFactory" />
16. </bean>
18. <bean id="userDao"
19. class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
20. <!-- 配置事务管理器 -->
21. <property name="transactionManager" ref="transactionManager" />
22. <property name="target" ref="userDaoTarget" />
23. <property name="proxyInterfaces" value="com.bluesky.spring.dao.GeneratorDao" />
24. <!-- 配置事务属性 -->
25. <property name="transactionAttributes">
26. <props>
27. <prop key="*">PROPAGATION_REQUIRED</prop>
28. </props>
29. </property>
30. </bean>
31. lt;/beans>

 

 

第二种方式：所有Bean共享一个代理基类

Java代码

1. <bean id="sessionFactory"
2. class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
3. <property name="configLocation" value="classpath:hibernate.cfg.xml" />
4. <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />
5. </bean>
7. <!-- 定义事务管理器（声明式的事务） -->
8. <bean id="transactionManager"
9. class="org.springframework.orm.hibernate3.HibernateTransactionManager">
10. <property name="sessionFactory" ref="sessionFactory" />
11. </bean>
13. <bean id="transactionBase"
14. class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"
15. lazy-init="true" abstract="true">
16. <!-- 配置事务管理器 -->
17. <property name="transactionManager" ref="transactionManager" />
18. <!-- 配置事务属性 -->
19. <property name="transactionAttributes">
20. <props>
21. <prop key="*">PROPAGATION_REQUIRED</prop>
22. </props>
23. </property>
24. </bean>
26. <!-- 配置DAO -->
27. <bean id="userDaoTarget" class="com.bluesky.spring.dao.UserDaoImpl">
28. <property name="sessionFactory" ref="sessionFactory" />
29. </bean>
31. <bean id="userDao" parent="transactionBase" >
32. <property name="target" ref="userDaoTarget" />
33. </bean>
34. </beans>

 

 

第三种方式：使用拦截器

Java代码

1. <bean id="sessionFactory"
2. class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
3. <property name="configLocation" value="classpath:hibernate.cfg.xml" />
4. <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />
5. </bean>
7. <!-- 定义事务管理器（声明式的事务） -->
8. <bean id="transactionManager"
9. class="org.springframework.orm.hibernate3.HibernateTransactionManager">
10. <property name="sessionFactory" ref="sessionFactory" />
11. </bean>
13. <bean id="transactionInterceptor"
14. class="org.springframework.transaction.interceptor.TransactionInterceptor">
15. <property name="transactionManager" ref="transactionManager" />
16. <!-- 配置事务属性 -->
17. <property name="transactionAttributes">
18. <props>
19. <prop key="*">PROPAGATION_REQUIRED</prop>
20. </props>
21. </property>
22. </bean>
24. <bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
25. <property name="beanNames">
26. <list>
27. <value>*Dao</value>
28. </list>
29. </property>
30. <property name="interceptorNames">
31. <list>
32. <value>transactionInterceptor</value>
33. </list>
34. </property>
35. </bean>
37. <!-- 配置DAO -->
38. <bean id="userDao" class="com.bluesky.spring.dao.UserDaoImpl">
39. <property name="sessionFactory" ref="sessionFactory" />
40. </bean>
41. </beans>

 

 

第四种方式：使用tx标签配置的拦截器

Java代码

1. <context:annotation-config />
2. <context:component-scan base-package="com.bluesky" />
4. <bean id="sessionFactory"
5. class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
6. <property name="configLocation" value="classpath:hibernate.cfg.xml" />
7. <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />
8. </bean>
10. <!-- 定义事务管理器（声明式的事务） -->
11. <bean id="transactionManager"
12. class="org.springframework.orm.hibernate3.HibernateTransactionManager">
13. <property name="sessionFactory" ref="sessionFactory" />
14. </bean>
16. <tx:advice id="txAdvice" transaction-manager="transactionManager">
17. <tx:attributes>
18. <tx:method name="*" propagation="REQUIRED" />
19. </tx:attributes>
20. </tx:advice>
22. <aop:config>
23. <aop:pointcut id="interceptorPointCuts"
24. expression="execution(* com.bluesky.spring.dao.*.*(..))" />
25. <aop:advisor advice-ref="txAdvice"
26. pointcut-ref="interceptorPointCuts" />
27. </aop:config>
28. </beans>

 

 

第五种方式：全注解

Java代码

1. <context:annotation-config />
2. <context:component-scan base-package="com.bluesky" />
4. <tx:annotation-driven transaction-manager="transactionManager"/>
6. <bean id="sessionFactory"
7. class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
8. <property name="configLocation" value="classpath:hibernate.cfg.xml" />
9. <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />
10. </bean>
12. <!-- 定义事务管理器（声明式的事务） -->
13. <bean id="transactionManager"
14. class="org.springframework.orm.hibernate3.HibernateTransactionManager">
15. <property name="sessionFactory" ref="sessionFactory" />
16. </bean>
18. </beans>

 

 

此时在DAO上需加上@Transactional注解，如下：

Java代码

1. package com.bluesky.spring.dao;
3. import java.util.List;
5. import org.hibernate.SessionFactory;
6. import org.springframework.beans.factory.annotation.Autowired;
7. import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
8. import org.springframework.stereotype.Component;
10. import com.bluesky.spring.domain.User;
12. @Transactional
13. @Component("userDao")
14. public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
16. public List<User> listUsers() {
17. return this.getSession().createQuery("from User").list();
18. }
21. }
