spring 事宜配置方法

spring 事务配置方法

Spring配置文件中关于Spring事务配置总是由三个组成部分，分别是DataSource、TransactionManager和代理机制这三部分，无论哪种配置方式，一般变化的只是代理机制这部分。

DataSource、TransactionManager这两部分只是会根据数据访问方式有所变化，比如使用Hibernate进行数据访问时，DataSource实际为SessionFactory，TransactionManager的实现为 HibernateTransactionManager。

具体如下图：

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

1. <?xml?version="1.0"?encoding="UTF-8"?>? <beans?xmlns="http://www.springframework.org/schema/beans"?
2. ????xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"? ????xmlns:context="http://www.springframework.org/schema/context"?
3. ????xmlns:aop="http://www.springframework.org/schema/aop"? ????xsi:schemaLocation="http://www.springframework.org/schema/beans ?
4. ???????????http://www.springframework.org/schema/beans/spring-beans-2.5.xsd ? ???????????http://www.springframework.org/schema/context ?
5. ???????????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">? ????<bean?id="sessionFactory"? ?
6. ????????????class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">? ? ????????<property?name="configLocation"?value="classpath:hibernate.cfg.xml"?/>? ?
7. ????????<property?name="configurationClass"?value="org.hibernate.cfg.AnnotationConfiguration"?/>? ????</bean>??? ????<!--?定义事务管理器（声明式的事务）?-->? ?
8. ????<bean?id="transactionManager"? ????????class="org.springframework.orm.hibernate3.HibernateTransactionManager">?
9. ????????<property?name="sessionFactory"?ref="sessionFactory"?/>? ????</bean>? ????<!--?配置DAO?-->?
10. ????<bean?id="userDaoTarget"?class="com.bluesky.spring.dao.UserDaoImpl">? ????????<property?name="sessionFactory"?ref="sessionFactory"?/>?
11. ????</bean>?
12. ????<bean?id="userDao"? ? ????????class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">? ?
13. ???????????<!--?配置事务管理器?-->? ? ???????????<property?name="transactionManager"?ref="transactionManager"?/>???? ?
14. ????????<property?name="target"?ref="userDaoTarget"?/>? ? ?????????<property?name="proxyInterfaces"?value="com.bluesky.spring.dao.GeneratorDao"?/>?
15. ????????<!--?配置事务属性?-->? ? ????????<property?name="transactionAttributes">? ?
16. ????????????<props>? ? ????????????????<prop?key="*">PROPAGATION_REQUIRED</prop>?
17. ????????????</props>? ? ????????</property>? ?
18. ????</bean>? ? </beans>?

第二种方式：所有Bean共享一个代理基类

1. <?xml?version="1.0"?encoding="UTF-8"?>? <beans?xmlns="http://www.springframework.org/schema/beans"?
2. ????xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"? ????xmlns:context="http://www.springframework.org/schema/context"?
3. ????xmlns:aop="http://www.springframework.org/schema/aop"? ????xsi:schemaLocation="http://www.springframework.org/schema/beans ?
4. ???????????http://www.springframework.org/schema/beans/spring-beans-2.5.xsd ? ???????????http://www.springframework.org/schema/context ?
5. ???????????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">? ????<bean?id="sessionFactory"? ?
6. ????????????class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">? ? ????????<property?name="configLocation"?value="classpath:hibernate.cfg.xml"?/>? ?
7. ????????<property?name="configurationClass"?value="org.hibernate.cfg.AnnotationConfiguration"?/>? ????</bean>??? ????<!--?定义事务管理器（声明式的事务）?-->? ?
8. ????<bean?id="transactionManager"? ????????class="org.springframework.orm.hibernate3.HibernateTransactionManager">?
9. ????????<property?name="sessionFactory"?ref="sessionFactory"?/>? ????</bean>? ????<bean?id="transactionBase"? ?
10. ????????????class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"? ? ????????????lazy-init="true"?abstract="true">? ?
11. ????????<!--?配置事务管理器?-->? ? ????????<property?name="transactionManager"?ref="transactionManager"?/>? ?
12. ????????<!--?配置事务属性?-->? ? ????????<property?name="transactionAttributes">? ?
13. ????????????<props>? ? ????????????????<prop?key="*">PROPAGATION_REQUIRED</prop>? ?
14. ????????????</props>? ? ????????</property>? ?
15. ????</bean>?
16. ????<!--?配置DAO?-->? ????<bean?id="userDaoTarget"?class="com.bluesky.spring.dao.UserDaoImpl">?
17. ????????<property?name="sessionFactory"?ref="sessionFactory"?/>? ????</bean>? ????<bean?id="userDao"?parent="transactionBase"?>? ?
18. ????????<property?name="target"?ref="userDaoTarget"?/>?? ? ????</bean>?
19. </beans>?

第三种方式：使用拦截器

1. <?xml?version="1.0"?encoding="UTF-8"?>? <beans?xmlns="http://www.springframework.org/schema/beans"?
2. ????xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"? ????xmlns:context="http://www.springframework.org/schema/context"?
3. ????xmlns:aop="http://www.springframework.org/schema/aop"? ????xsi:schemaLocation="http://www.springframework.org/schema/beans ?
4. ???????????http://www.springframework.org/schema/beans/spring-beans-2.5.xsd ? ???????????http://www.springframework.org/schema/context ?
5. ???????????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">? ????<bean?id="sessionFactory"? ?
6. ????????????class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">? ? ????????<property?name="configLocation"?value="classpath:hibernate.cfg.xml"?/>? ?
7. ????????<property?name="configurationClass"?value="org.hibernate.cfg.AnnotationConfiguration"?/>? ????</bean>??? ????<!--?定义事务管理器（声明式的事务）?-->? ?
8. ????<bean?id="transactionManager"? ????????class="org.springframework.orm.hibernate3.HibernateTransactionManager">?
9. ????????<property?name="sessionFactory"?ref="sessionFactory"?/>? ????</bean>? ?
10. ?? ? ????<bean?id="transactionInterceptor"? ?
11. ????????class="org.springframework.transaction.interceptor.TransactionInterceptor">? ? ????????<property?name="transactionManager"?ref="transactionManager"?/>? ?
12. ????????<!--?配置事务属性?-->? ? ????????<property?name="transactionAttributes">? ?
13. ????????????<props>? ? ????????????????<prop?key="*">PROPAGATION_REQUIRED</prop>? ?
14. ????????????</props>? ? ????????</property>? ?
15. ????</bean>?
16. ????<bean?class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">? ? ????????<property?name="beanNames">? ?
17. ????????????<list>? ? ????????????????<value>*Dao</value>?
18. ????????????</list>? ? ????????</property>? ?
19. ????????<property?name="interceptorNames">? ? ????????????<list>? ?
20. ????????????????<value>transactionInterceptor</value>? ? ????????????</list>? ?
21. ????????</property>? ? ????</bean>??? ????<!--?配置DAO?-->?
22. ????<bean?id="userDao"?class="com.bluesky.spring.dao.UserDaoImpl">? ????????<property?name="sessionFactory"?ref="sessionFactory"?/>?
23. ????</bean>? </beans>?

第四种方式：使用tx标签配置的拦截器

1. <?xml?version="1.0"?encoding="UTF-8"?>? <beans?xmlns="http://www.springframework.org/schema/beans"?
2. ????xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"? ????xmlns:context="http://www.springframework.org/schema/context"?

4. ????xsi:schemaLocation="http://www.springframework.org/schema/beans ? ???????????http://www.springframework.org/schema/beans/spring-beans-2.5.xsd ?
5. ???????????http://www.springframework.org/schema/context ? ???????????http://www.springframework.org/schema/context/spring-context-2.5.xsd ?
6. ???????????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?/>?

9. ????????<property?name="configLocation"?value="classpath:hibernate.cfg.xml"?/>? ? ????????<property?name="configurationClass"?value="org.hibernate.cfg.AnnotationConfiguration"?/>?
10. ????</bean>???
11. ????<!--?定义事务管理器（声明式的事务）?-->? ? ????<bean?id="transactionManager"?
12. ????????class="org.springframework.orm.hibernate3.HibernateTransactionManager">? ????????<property?name="sessionFactory"?ref="sessionFactory"?/>?
13. ????</bean>?
14. ????<tx:advice?id="txAdvice"?transaction-manager="transactionManager">? ????????<tx:attributes>?
15. ????????????<tx:method?name="*"?propagation="REQUIRED"?/>? ????????</tx:attributes>?
16. ????</tx:advice>?
17. ????<aop:config>? ????????<aop:pointcut?id="interceptorPointCuts"?
18. ????????????expression="execution(*?com.bluesky.spring.dao.*.*(..))"?/>? ????????<aop:advisor?advice-ref="txAdvice"?
19. ????????????pointcut-ref="interceptorPointCuts"?/>??????? ? ????</aop:config>????? ?
20. </beans>?

第五种方式：全注解

1. <?xml?version="1.0"?encoding="UTF-8"?>? <beans?xmlns="http://www.springframework.org/schema/beans"?
